LOSSIGY12V 100AH LiFePO4 Lithium Battery with 100A BMS, 1280Wh Deep Cycle Power Supply, Perfect for Solar System, RV, Marine, Off Grid, Golf Cart,

Been using two of these batteries with my 800 wat solar set up off grid and these batteries have never failed me going on 5 years now. The are just great! I've had other brands none have lasted this long

Purchased this battery to go in my vintage travel trailer. It’s unique size fit perfectly in the space I had. Item arrived in good condition and was well packaged. It arrived with 13.2 volts. I don’t use inverters or high power draw appliances so my draw down test involved leaving the lights on in the trailer. After charging the battery fully I commenced the test. After sitting for a few days after a full charge with no draw it settled on 13.45 volts. This doesn’t match up with online voltage and state of charge charts so I was a bit worried. After 4 days or so with the lights on my calibrated Victron smart shunt registered close to 190 AH drawn from the battery with a voltage of around 12.3. I was satisfied with its performance. I run LED lights, water pump, 12 volt TV, and blower fans for the heater. Power to spare.

I’ve had this battery for two years in my camper. It’s always fully charged hooked up through solar really really good battery well worth the money.

2/15/23 update - in the end I have a working battery that has been working fine since they helped with my issue. Added stars to rating to reflect willingness to make it right.8/1 update - received charger and will be testing it out on the battery to see if it’ll kick start the BMS to allow for proper charging of the battery. Will allow charger to fully charge and test battery over a weeks time before responding back. Added one star (now at 3 stars) as seller seems dedicated to fixing the battery issue.7/21 update - support answered request in a few hours. Said they’d try sending out their propriety charger giving a response about the BMS kicking in. Unsure this will do anything as the charger I’ve tried which is set to their exact specs hasn’t done anything. Will give theirs a try to try and save the hassle of warranty. Still extremely disappointed. Other battery brands have been running smoothly for us for years. Not a good sign honestly.My battery was delivered June 10th. It worked flawlessly for a few weeks. With the load I had running (a Starlink Dishy and nest camera) it only lost around 12% per night. It quickly degraded however. Now, only 1.5 or so months later, the battery goes fully dead into shutoff after 2-3 hours at night. No change in load, or environment, or anything. I’m extremely disappointed having spent so much and to have gotten so little time. Emailed today about a warranty replaced but have not heard back which is ok since I’d expect a few days time in response. I’ll continue to update this review as warranty replaced goes down the path. Hopefully this is a one time issue and hopefully the warranty process goes smoothly. 1 star rating at this moment due to extremely limited lifespan but they could redeem up to 3 additional stars for a good warranty process.

No scams of added weight with this battery tests out good

This review is more focused on the seller RCLithium. Their customer service sucks. The batteries are decent and worked well-ish. I bought two in July of 2023. They recently failed after a brutal cold front we had. No, I was not charging them below freezing. They state they have a 5-year warranty on them. I sent RCLithium a chat and was given the runaround. I decided to buy two LiTime batteries instead. I've had a pretty decent experience with Lossigy batteries, minus this recent failure, but RCLithium the seller is bad. Bad to the point I decided to pay more and buy different batteries from a different seller. One final note, I could NEVER get these batteries to a 13.4-13.8 charge. EVER. The most, even after following RCLithiums instructions, was 13.3. And I have Victron SCC providing and regulating the charge. Take that for what its worth.

I have two sets of 4 of these batteries and have never had an issue. I worked the math to make sure I never over tax the BMS (battery will die if BMS breaks connection). I have added other batteries to the system and all work as advertised.I'm on year 4 on one set and year 3 on the other set, and doing the "ball park" math for running my house off solar and batteries at night, they are still holding close to 100% of the 10KW-DC per set as of this writing. I'm happy with these and would recommend this maker to others.

I've owned the 300ah 12v Lossigy battery for 4 months. It's dead. I've tried every imaginable way to revive it. Can I get a replacement? FYI: Lossigy is ignoring me.
