Features

  • Bluetooth Function: Compared with the traditional battery monitor, CHINS Bluetooth lithium battery has added Bluetooth function and obtain various data (SOC) of the lithium iron phosphate battery. Customers can connect to the battery through the mobile phone APP, and read the battery voltage, current, battery capacity and other important information at any time. Wireless connection range: within 5-10 meters from the battery.
  • Heating Function: Only when Smart battery starts to charge, the heating function inside the battery can be turned on. When the ambient temperature is lower than 32F (0C), the charging current will only supply power to the heating film inside the battery. When the internal temperature of the battery reaches 50F (10C), BMS will immediately turn off the heating function, all the charging current charges the battery. The charging current of the low temperature heating battery is at least 10A.
  • Lithium Iron Technology: CHINS Bluetooth lithium ion battery have exceptional longevity since they manufacturing by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power, letting you use the battery more freely. Our batteries are more cost effective, so when factoring time and cost into your purchase, our lithium ion battery banks come out ahead every time. It can support fast charging and solar panel charging.
  • Capacity Expansion: CHINS LiFePO4 battery can be connected in parallels and in series for larger capacity and voltage. Max connection in series: Up to 4 identical batteries for up to 48V connecting in series. Connection in parallels: it can connect multiple batteries, suggest no more than 4pcs in parallel. Allow to be extended up to 4 in series and 4 in parallel (Max 4S4P) to get more capacity (Max 800Ah) and higher voltage (24V, 36V, 48V). Other installation methods: 4S2P, 2S2P, 3S2P, etc.
  • Built-In BMS & Convenience & Maintenance Free: CHINS Bluetooth LiFePO4 battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. Built-in high temp cut off prevents charging over 122 F (50 C). Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults.

The media could not be loaded. I am giving it four stars and will update it after having more time to use and evaluate the battery's performance in my RV. I decided to give CHINSUS a try after watching a few videos. Will Prowse has some good videos with teardown and evaluation of capacity. The Projects in Paradise channel has some good videos showing a great setup. The one thing I could not find was videos related to the "Heating" function. I live in an area where we will have at least a three-month window with temperatures well below freezing, and I will use my Truck Camper in these temps. In the one video I could find that talks about the "heating" function, his tests did not prove this functionality. In my testing, the BMS did protect the battery when the battery's internal temperature dropped below freezing. I will provide some photos and a quick video to demonstrate the BMS blocking the battery and the behavior observed with some smart chargers. The App advertised and available for the 100Ah battery appears different from the 200Ah and 300Ah batteries. "UpNorth Mike" has a video on his youtube channel that shows what the 200Ah Bluetooth App looks like. Reviewing other people's posts shows the 200Ah Bluetooth App, and it is different from the App for the 100Ah battery. I will post screenshots of the 100Ah Bluetooth App so you can see the difference. The 100Ah App has most of the same features. The main window shows the State of Charge as a %, current-voltage, current amperage, rated capacity, the number of cycle times, temperature 1 and 2, and if the BMS is allowing for safe charge or discharge. As you can see in the screenshot, when the battery dropped below freezing (0 Celsius), the BMS turned off the charging capability while the discharge capability remained on. CHINS is using the basic functionality on the iOS App, so it appears as if it is a button you can toggle on and off. This is not the case; you cannot toggle it on and off and bypass the BMS. Interestingly, I have noticed there is always a 1 to 2 degree C temperature variance between the two temp sensors. I am not sure where the two sensors are, and I am not in a position where I can afford to tear one apart and diagnose where they are. I have not monitored closely enough to see if BMS shuts off the charge feature when only one sensor reaches unsafe temperatures or if both sensors are needed to disable the charge functionality. I placed the battery outside overnight to drop temps, and the core temperature on both sensors had dropped below freezing when I checked the following morning. Weather forecasts showed we would be sub-freezing but not go to dangerous levels for lithium. When using different chargers, I observed that many chargers would not enable the heat tape. The manual states that the heating film will automatically activate when the battery receives charging conditions. Under this heating phase, the BMS would not charge the battery until the core battery temperature had risen above 10 C (50 F). With my observations, the BMS turned the charging back on at ~8 C; this is well above the freezing, so I was not concerned, but obviously, it did not behave exactly as described in the manual. I tried multiple chargers, and many would not supply current long enough to activate the heating film, instead immediately responding with either bad or already charged battery status. Most smart battery chargers will run quick diagnostics on the battery to analyze the battery before engaging the charge current. The safety feature of the BMS is faking the charger out, and it will immediately show "bad battery" vs. supplying charge current, as noted in a video I will try and include. These same battery chargers had no issues charging the battery when the BMS was not blocking because of the cold temps. I tried brand new smart chargers (NOCO Genius and a Schumacher Rapid Charger) and even tried an old (25+) year old Sears Charger. The older charger would immediately show the battery as charged, and the analog meter would drop to 0 Amps. I am looking at the Victron Energy Blue Smart IP65 12-Volt 15 amp Battery Charger (Bluetooth) - one of its features advertises: "Blue Smart IP65 Charger will attempt to recharge a deeply-discharged battery by force-feeding it with a low current. Normal charging will then be resumed as soon as there is sufficient voltage across the battery terminals." I understand that the heat tape needs five amps, so I am still researching what Victron's low current force-feeding feature provides. I should note that the battery charger in the Lance Camper kicks the heat film with no problem. I am still evaluating what happens with a solar setup. I have an older and a newer BlueSky charge controller that I am still evaluating. I reached out to CHINS with a question about the heat film, and they were quick to respond. Their response: "Many manufacturers of lithium battery chargers first test the voltage of the battery. If the tested voltage data is lower than the parameters they set, these chargers will not charge the LiFePO4 Battery. Our 14.6V 10A lithium battery charger, it includes 0V charging function, it can activate the BMS of any lithium battery, and can also charge all 12.8V lithium batteries." Their response seems to align with what I have been seeing with my testing. The charger you use must have the 0V charging function to supply enough current to activate the heat film. I will look to post back when I have run some more tests and evaluate the battery's functionality through normal RV usage. From an RVers standpoint, I am very pleased with what I have observed so far. Using the App to monitor the battery and see the State of Charge as a percentage will be fantastic. No more guessing your batteries state with the traditional Red, Yellow, and Green indicator lights or evaluating based on current voltage as the voltage readings on a traditional lead-acid can fluctuate greatly while under load. While there are some great features on the App, it lacks a few areas. The 100Ah App does not show anything related to the heating functionality. The only indication it shows is that BMS has disabled charging. One full screen shows "Protection Status," there are numerous data points, but the indicators and datapoints only use Acronyms (SOCC, OTC, UTC, COV, FC, CHG, and 19 others). If you are not knowledgeable about what they all mean, assessing what is being displayed could be challenging. As initially noted, my overall initial impressions are favorable. CHINSUS was quick to respond to questions that I have had, and the battery appears to be performing as designed. The price point is excellent when comparing options. As you can see in the picture where it is mounted in my camper, the previous owner had a lead-acid battery leak, which is very evident from the acid stains down the side of the camper. I will no longer have to climb up to check the battery water levels and worry about acid issues, as lithium does not have these issues. Less weight, less maintenance, no gassing, and hopeful for 2000+ cycles so that it will last 5+ times longer than a lead-acid with much less hassle. The App provides information that will be helpful. I am going with four stars because I have not had enough time to prove things out, but I will update my post as I have the chance to observe the battery under additional scenarios within my RV. ... show more

Too early to tell about longevity and battery life as I've just installed it and camping season is a couple of months away. It took me a while to fabricate the setup for a new battery box on my trailer tongue as I don't have a lot of room between the propane bottles and the trailer body. The 200ah battery fits in an 8D battery box with a little room on all sides. I insulated the box quite a bit on all 6 sides so it'll hold up better for cold weather charging. One concern was whether it had enough cold cranking amps to start my 4,000 watt Onan generator. The BMS says 600A for "less than 5 seconds". I didn't log the inrush current draw when I tested out the generator start but it did start my generator without any noticeable problems once I got the system primed with fuel. I'll be changing out my converter to one that has a LiFePo4 charging profile sometime between now and Spring as well as changing out my solar charge controller for the same reason. My trailer is a 2016 and neither the converter nor solar charge controller have Lithium compatible charging profiles. I'll upgrade both in order to be able to charge to 100%. Nice weight savings, the 2 x 100ah flooded lead/acid batteries I had previously installed were over150 lbs between the two of em. This one is under 50 lbs and theoretically I'll get 2X the usable watt/hours. It was super handy to put a couple of aluminum buss bars on the terminals to create 4 mounting points on each electrode, I didn't want to stack up multiple connectors on the one battery terminal. So far so good, time will tell to see how the thousands of cycles play out in a real world environment, but I'm fairly confident this battery will support boondocking for 6-7 days before recharging with my typical usage. Couple months later now. The battery didn’t hardly discharge at all in storage. Only lost 1% SOC over 3 months of storage. Plugged into my tow vehicle, 25 amps came in from the truck for a couple of minutes until the BMS shut down the incoming charge current. My 200 watt solar array was adding about 90 watts of incoming charge current in the indirect, morning sunlight. Bluetooth app is a little quirky and minimally featured. If you walk far enough away from the battery, you lose connection. You have to then kill the app and launch it again to reestablish Bluetooth connectivity. So far so good. I’ll know more after a short trip this weekend on how well they discharge and top off from solar panels during typical usage. After a few months now: Capacity should keep me going for 8-10 days boondocking without any incoming charge. That said, my 200w solar array will bring in up to 120-150 watts during a good sunny day and will bring the battery back up to 99% SOC in a few hours. The updated 110v/12v converter will supply up to 57 amps and will bring this battery back up to high SOC in short order. So plugged into commercial power or running my generator will supply a huge charge current. The legacy solar charge controller is set to an AGM profile as mine is old enough to not have a LiFePo4 profile, but after a day of solar charging it brings the battery up to high SOC no problem, I'll not upgrade to a newer one until this one dies. So far, I've not seen my SOC drop below 85% as there's been enough sun every few days to top the battery off, or I've towed the trailer and it's gotten topped off from the truck, or I've run the generator for a little bit. So far quite happy with the upgrade. ... show more
