  • 5.0 out of 5 stars Quality Battery
Style: 12V 50AH
I’ve bought several LiFePO4 batteries, and so far these are the best. The others either don’t provide the specified amp-hours or have a less suitable BMS that caused problems. A little info on BMS… Battery Management Systems (BMS) are required with lithium batteries to keep bad things from happening. Although LiFePO4 batteries are much better that LiPo batteries, they still don’t like over-charge, over-discharge, and short circuits. This requires an electronic system that monitors not only the total battery voltage, but each cell in the battery. Minor variations cause some cells to charge or discharge faster than others, so each cell must be monitored individually. The BMS does this and also tries to “balance” the voltage between cells. This is a good thing. The drawback is that when the BMS determines that the battery is fully charged, it will disconnect the battery to prevent overcharge. This can cause some weird issues. In my 12v solar lighting system, the battery is charged during the day (obviously). Even though I’m using a separate solar battery charge controller, when the BMS detects a fully charged battery, it will disconnect it. This allows the higher charging voltage from the solar panels to pass directly to the lights, causing a change in brightness. Depending on your solar panels output, this higher voltage could cause damage. I’m now using a 12V 20A power regulator between the battery and the lights eliminating the issue. It took me a while to figure out what was causing the light to suddenly get super bright. For the technically inclined, the BMS disconnects at 14.4V allowing up to the 19V output from my panels through. I’ve adjusted the solar controller to limit the charge to 14.3V which mostly eliminates the issue, but the regulator will add additional protection. Some of the other LiFePO4 batteries I’ve tried had BMS that cut out at lower voltages that made this much worse and prevented the battery from fully charging. ... show more

  • 5.0 out of 5 stars Best customer service I have ever encountered.
Style: 12V 200AH
You MUST understand the following when designing your solar power system. Power is measured in watts. Volts times amps equals watts. 12 volts times 10 amps equals 120 watts. 120 volts times 10 amps equals 1,200 watts. I thought amps were amps, so I designed my system thinking I could run my 10 amp (1,200 watt) microwave for 40 hours with 400 amp hours of battery storage. Wrong. 1,200 watts at 120 volts is 10 amps, but 1,200 watts at 12 volts is 100 amps of continuous power draw from the battery. My system turned out have 1/10th as much power as I thought it would have, but I didn't know that. I have been dealing with power issues since I started living in my van 4 months ago. Every time I ran the microwave for for more than two minutes the batteries would shut themselves off then come back on a few seconds later. It turns out the 200ah 100 amp BMS (Battery Management System) batteries I bought couldn't handle the power draw. I had to replace them with 200ah PLUS batteries with the 200 amp BMS, which allows for 200 amps of continuous power draw. It took me forever to figure out what the problem was. These guys went way out of their way to help me on numerous occasions, including paying for shipping AND packing when returning a battery that turned out to have nothing wrong with it. I bought the batteries after seeing a YouTube video where a guy cut one open and was impressed with the quality construction. The batteries work great and other people I know with Chins batteries have never had any issues with them. The prices are better than most. What really sets this company apart though is the customer service, which is the best I have ever encountered. I have been repeatedly impressed by their responsiveness to my technical questions as I tried to discover what was causing my power problems. So yeah, I highly recommend Chins batteries. ... show more

  • 5.0 out of 5 stars Two of these wired in Serial work great to power Minn Kota Ulterra 24v 80lb thrust troller motor
Style: 12V 100AH
These are great. I replaced two Interstate lead-acid deep cycle batteries (SRM-27's), and can't believe how much better (and longer) the Minnkota Ulterra functions with these LifePO4 batteries! First, as mentioned I use two of these 12v batteries wired in series to power the 24v Ulterra trolling motor that is mounted on a Carolina Skiff 23UE's bow. The batteries are charged with a Noco GENPRO10X4 12V 4-Bank, 40-Amp On-Board Battery Charger, which allows me to individually select the type of battery for each of the four batteries on the boat to Lead/Acid, Gel, AGM, or Lithium. Obviously, the two CHINS 100AH LifePo4's are set to "Lithium." They needed to be charged upon receipt of the batteries, and I let them charger overnight. No problem. The Ulterra is very sensitive to voltage. Regular Lead and sealed (agm) batteries drop voltage as you use them, causing problems where the Ulterra stops functioning, except at very low speeds. After experiencing many error codes on the Ulterra after an hour or less of use ( if running more than speed 5 (of 10)), I called Minnkota who said, "the Ulterra needs the batteries to have voltage of 12.6v per battery under a load for a combined reading 25.2v total," or it will turn off, as I was experiencing. My multimeter showed that the voltage of the two Interstates (only about 3 months old) was dropping well beneath the 25.2 threshold almost all the time at load -- dropping beneath the 25.2 that Minn Kota wants to 24.6v at speed 5 of 10. To better check and understand and track, I installed a Victron BMV-712 ( https://www.amazon.com/Victron-Energy-MONITOR-VTBMV-S-BMV-712-Battery/dp/B075RTSTKS/ref=sr_1_5?crid=2LK4SOA30P2XT&keywords=Victron%2B712&qid=1650131508&sprefix=victron%2B712%2Caps%2C94&sr=8-5&th=1 ). It confirmed my multimeter readings but allowed more much more detailed tracking. The lead batteries were not maintaining sufficient voltage output. When brand new, they worked better. Likely, I ran them below the 50% charge level a few times without knowing it, and might have damaged them. That's another benefit you'll read about LifePO4's over traditional deep cycle batteries. The lead flavors are not supposed to be run beyond 50% of their rated capacity, so you should only use 44AH of an 88AH battery, or it can be damaged. The LifePO4's can go low. I've taken these to 20% without any problems, and have heard of others going to 10%. Getting them to 20% was a long day of running the trolling motor. The voltage on the two LiFePO4's (in Series) stays in the range of 26.9 to 26.0v under load when operating between Ulterra speeds 1 to 7.5 of 10. It drops into the 25's at speed 8 to 10, but never drops below 25.4, which was at speed 10 with about 50% of the AH's consumed already. Excellent!! These batteries are great!! Strongly recommend for the Ulterra 24V and imagine they would also be great for the 36V Ulterra if you buy three of them. Remember to buy, have, or install a proper lithium battery charger for these, too. One word of caution, I try to avoid running the Ulterra at the high speeds 7.5 or higher for long periods of time (30 minutes) with the LiFePO4's because Minn Kota's website mentioned that the motors were designed with Lead Acid durations in mind, not the much longer durations without voltage drops that we can get from the lithium batteries. Also, the Victron has an alarm that notifies me when the only 15% of the battery capacity remains. Lithium batteries hold their voltage very well until the end, then really, really drop. I'm concerned there would not be sufficient voltage to Stow the Ulterra if I ran it to the end of capacity. ... show more
