LOSSIGY24V 100AH Bluetooth Lithium LiFePO4 Battery Built-in 100A BMS, 2560Wh Deep Cycle Power Supply, Perfect for Solar System, RV, Off Grid, Marine, Trolling Motor

The batteries are GREAT! I use them for a trolling motor and they never run out!!! We typically troll all day and would run out the old high end lead batteries by early to midafternoon, but we never ran out these!!! Even fishing all day into late evening, we still had more than 75%!!! Wow!!! They are AWESOME!!! THANKS!!! I would definitely purchase again!!! In addition, they each weigh about 50 lbs less than the old lead batteries! Easy to install!!!

I originally ordered this product after watching a YouTube review done by DIY Solar with Will Prowse. Unfortunately the first battery I received from them failed out-of-box due to a faulty BMS. Confirmed this with two of my existing solar set-ups and was frustrated. HOWEVER, I reached out to the seller on Amazon and provided them with the details of my troubleshooting and the situation. Their response was prompt, courteous, and they immediately shipped me a replacement. When the new battery arrived a few days later, it worked FLAWLESSLY. The seller maintained good communication along the way, provided me with tracking information and a return mail label for the bad battery. They went above and beyond to make it right, something you don't see too often these days. My overall experience ended up being very positive. I would highly recommend this product and the seller, I will definitely purchase from them in the future!

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 have several editions of Lossigy batteries. All have performed beyond expectation. Even better, Customer Support - when needed - has been first class. These may not be top-of-the-line LiFePO4 batteries, but they fit my needs and my budget.I whole-heartedly recommend a prospective buyer give these batteries a try. I did and I like them.5 stars.

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.

I bought two of these for my Roadtrek Ranger, they fit in the house battery compartment with room to spare. They have been working great although I updated the other components to be LiFePo compatible. I ran each battery down before charging and I stopped after 98 AH was supplied, so I feel you can trust the capacity ratings. They came nicely packaged and look decently made. The main issue that potential buyers need to be aware of is that the output amperage is limited by the internal BMS to 50 amps so double check your design needs. For some uses that limit may be a problem. But I give them a thumbs up!

I retrofitted my camper to lithium with this battery. After changing the charger in the camper and adding a dc to dc charger for the tow vehicle to charge the lithium battery my system is up and running now. I hope the longevity is as good as expected. I will test it out with a month long camping trip and see how well it works in the real world.

I connected 2 12 V 100 A batteries to get 24 V for trolling motor. Use it once and left it for three weeks. Try to charge it but it would not charge try to correct the cells but still could not fully charge.
