Features

  • Superior Performance: Lithium Iron Phosphate battery consists of 4 Grade A+ cells, which have 3-5 times higher energy density than lead-acid batteries and no memory effect, so you don't have to worry about the battery life being shortened by frequent charging. Conforms to group31 standard design, fits seamlessly into Group31 battery box
  • Multi-dimensional Protection: 12V LiFePO battery is equipped with a highly integrated 100A BMS, which can detect abnormalities such as overvoltage, overcharging, overcurrent, short circuit, overheating, etc., and take protective measures to ensure the safe operation of the battery. BMS cuts off charging below -4F (-20C), high temp cut off prevents charging above 158F (70C)
  • 10 Years Lifespan: 12V marine battery can withstand 4,000-10,000+ charge/discharge cycles, and the self-discharge rate is less than 3%, which makes them longer-lasting and more durable than lead-acid batteries. If the battery is not used for a long time, please store it fully charged to extend the battery life
  • Diversified Uses: Rechargeable deep cycle batteries are very suitable for RVs, motorhome, camper, travel trailer and long winter energy storage systems, etc. Also great for 35-70lb thrust trolling motors, NOTE: When used on a boat, store in a Group 31 waterproof case
  • Various Charging Methods: Trolling motor battery can be charged with the included special charger. It can also be charged by connecting to a solar panel. The charging time varies depending on the intensity of light from the sun every day. You can also use the clip charger or generator to charge the battery

Update 1/9/22 Batteries are super stars. Been boondocking for months on these and our Solar with great success. Running 400ah @24v and zero issues. Getting advertised amp hours and running smoothly. Update: 9/26/21 Still very happy with these batteries. Traveled through national parks burning tons of amps with these running out air conditioner, PlayStation 5, computers every single night and have been very happy with the performance. Would purchase again. I'm converting a Ford Transit and wanted a really nice off the grid solar system that could realistically run the air conditioner on battery over night in warm climates. I shopped hard. Looked at everything from Bigbattery, SOK, battleborn, Chins etc. I spent a ton of time in DIY solar forum, youtube etc watching reviews and trying to figure out if I wanted to take the chance or not. I knew I could fall back on Amazon or even a charge back if it came to it so I went ahead and took the chance. I ordered 3 200 amp hour 24 volt batteries on 2/13/21 and they arrived well packaged and in new condition at my home on March 16th (early). There was an issue with one of the batteries being the wrong size (Shipping issue). I contacted the seller via email and they quickly rectified the problem and I am 100% satisfied with the outcome and their response. The seller has been easy to get in touch with, my emails have been returned promptly and they have bent over backwards to ensure that I was taken care of and never once asked me to sacrifice anything what so ever. Any company can sell you a product. The real question is will these people take care of you when there is a problem and I can say that I would 100% buy another battery from this company again. End of story. No BS. I spent a lot of money on these batteries and I would gladly buy them again. Ok, now to the performance. I used the included chargers to top off both batteries and ensure they were both fully charged separately. I let the batteries sit for a day after being fully charged and the voltages were identical on both for the duration of the charging and post disconnection. After connecting them to my inverter and wiring everything I ran my air conditioner, 48-52 amps @ 24v until my inverter disconnected the load at a conservative >10% thresh hold. I got 365 aH out of the bank with an ending voltage of 25.01 volts. I spent a lot of money on these and want them to last so I'm limiting charge voltage to 28v and discharge to no more than 90% of capacity. If you do the math you'll see there is plenty of juice left to exceed the 400ah rating on the batteries. Overall I am very pleased with the purchase. If I ever need another Lifepo4 I'll come right back here for it. I'm glad I took a chance on this seller and overseas batteries. I saved a lot of money. Short of getting your own cells and doing your own build these batteries are some of the best $/ah you can find on Amazon. ... show more

    • Works great!!!
Style: 12V 100Ah max
This really holds a long charge for my purpose. I run PDR lights removing hail damage. They last about 2 13-15 hour days on the hail lights most techs use.

    • I can't believe I lugged around a 90 lb lead acid battery for so long
Style: 12V 100Ah max
I have been debating moving to a lighter battery for my canoe for some time. I have used a nut-buster, 90lb marine deep cycle battery for years to power my Minn Kota 30. Lugging that monster I wonder why I never got a hernia. I did use a smaller deep cycle battery, but I ran out of power twice and had to paddle to get to the take-out. This year I decided to go light, to go Lithium. One thing I did not count on was the sticker shock. After two weeks of searching for good reviews AND a good price I settled on a LiFePO4 Battery 100Ah 12V 1280Wh Deep Cycle from SCREMOWER. I wanted at least 100Ah, with marine terminals, it came with an included 10A charger, and I would get it within five days. I received an e-mail stating item had shipped, so I started tracking FEDEX, but FEDEX showed they had not received the item yet and five days now stretched to seven days. Fortunately SCREMOWER has decent customer service and they responded to my query about delivery. They acknowledged they erred and apologized for the delay. The battery and charger arrived on Monday and I promptly charged the battery. Then I noticed the charger was only 7A. I contacted SCREMOWER and they told me the battery now ships with a 7A charger which is yields better battery life, and the charger is considered a gift. On the second day when I charged the battery, the charger started whining and making noise. The mini muffin fan was defective and was headed for failure. Another e-mail to SCREMOWER described the issue and after several e-mail exchanges SCREMOWER agreed to send me a replacement. I was informed that since the charger was a "gift" there was no warranty, but they would send me a replacement as part of "customer satisfaction". So far the battery has performed with issue. We tested it on the Saco river in Maine, taking care not to drain the battery. We need not have worried. We cruised all day, up river, down river, into a strong headwind, and still had ample power to spare. And talk about light - a mere 27lbs. What a pleasure to not have to strain just to carry the battery. I still have more testing to do now that boating season is about over. I may use the battery as a pellet stove backup supply, but that depends on what else is needed to connect to out Harman Advance Pellet Stove (converter, etc.). The battery also works well with my 2000 lb winch. ... show more

    • I used these to power a camper van
Style: 12V 120Ah
Along my cross country travels, I started encountering issues with battery life in the house part of my camper van thanks to old lead acid batteries. I found a wonderful person that offered to help me upgrade my entire battery system so I jumped on the opportunity! I chose these batteries due to reviews on Amazon and allow me to tell you how well they performed during the year that I had them before selling my van. I have zero doubt in my mind as to whether I would purchase these again or not because the clear answer is YES! What a great and dependable battery. 🫶🏼 So simple to install and insane how much lighter it was than the old lead acid monsters. ... show more

    • Won't recharge/ Poor customer service

After using the battery four times in the first month of owning it, it will now no longer hold a charge. The charger used to have a humming noise as if it were charging but it no longer does that. I decided to take it to a battery shop where they tested it and told me that the charger has ruined the battery and the battery will no longer hold a full charge. i tried contacting customer service but they said, 'send pictures" Send pictures? Of What? that the battery only charges 25%. Then they didn't bother replying. i would not recommend this product because of the run around the customer service has provided plus that the product isn't working correctly. ... show more
