WEIZE 12V 100Ah Mini LiFePO4 Battery, Built-in 100A Smart BMS, Deep Cycle Lithium Iron Phosphate Battery Perfect for RV, Solar, Marine, Trolling Motor, Off Grid Applications, Backup Sump Pump

Very good battery came charged. I’ve used it for over 2 years and have never had a problem with it. Easy to install. It’s a great battery for campers or off-grid enthusiasts

The batteries have worked well in our travel trailer so far. I purchased the Weize lithium charger as well to keep them maintained. They charge much faster than our previous deep cycle lead batteries.

Game changer, the life on this when running a trolling motor is exponentially better than a lead acid. You won't regret it just buy it. But make sure you get a proper charger. The battery size is small the power is mighty

This battery worked great for a few months but now it shuts off if I connect it to anything. It shows 12.2 volts on my volt meter and won't take a charge. I contacted Weize and they wanted some voltage readings before and after charging with pictures and asked about my charger. Then they wanted me to buy a new charger even though my charger works fine so I bought the Weize Lifepo4 charger but the battery still won't charge. Weize wanted more voltage readings and pictures and to hook in parallel with a good battery then charge. I have done all this more than once and they are asking for the same thing over and over. I keep doing tests and charging and sending pictures and they respond by asking me to do it again. It seems like each time I send a message to weize it is read by a different person and they don't read the previous messages. I did find another guy that had bought 6 of these batterys and 3 of them went bad within 2 months. Each had the same failure, a bad BMS. I think I will just use the cells from this battery and buy a good quality BMS. If I could get them to replace it and they send me one that fails again I will have just wasted more time.

Came fully charged, and stays charged for hours on my 62lb Newport Trolling motor. Charges super fast and stays charged for days. Great for the price, and super lightweight.

Nice battery

Upon charging these batteries for the upcoming fishing season both 100aH batteries would not accept or hold a charge. I thought it was my Minnkota digital 3 bank charger (which worked without issues in the past) so I purchased a new NOCO 3 bank 10A charger. I selected to "Lithium" and within 1 minute the charging cycle said it was complete. My volt meter read 12.92v on both batteries or approx. 50% SOC yet they would not accept more than that. I proceeded to email "[email protected]" with pictures and descriptions of my issues of what was going on, 5 days later I still didn't have a response so I called the phone number listed on their "support" webpage and got forwarded to an answering machine so I left a voicemail. I did not hear back from my attempts so far, then I emailed again asking if they received my original email. No response what so ever from all my attempts. The product may be good, affordable and they claim a 10 year warranty. With no customer service or technical support what good is the product if you have issues?

Worked like it should. However the plastic case handles are not uv proof the handles are now to brittle to use they have broken like uncooked pasta
