LOSSIGY 24V 100AH LiFePO4 Lithium Battery, Perfect for 24 Volt Trolling Motor, Solar System, RV, Marine, 2560Wh Built in BMS with Bluetooth

Great batteries for my boats trolling motor. Never had any issues with the three. This is the second set I’ve bought for the two different boats I’ve owned in the past 4 years. They keep the same amount of power all day long in tournaments.

The batteries were shipped much faster than the schedule predicted. I bought four. They were installed in our 41' 5th wheel in parallel to achieve a 400AH reserve capacity. They replaced two L16 6V 420AH lead acid batteries that were about four years old and were starting to demonstrate a reduced reserve capacity. The LG16s weight about 135lbs EACH! I cut about 125lbs in weight by going to the LiPo technology. Capacity test is still underway but I now 12 hours into running the coach on the battery pack. Now that the sun is back up I am charging the batteries at about 20 amps from my solar panels and the Blue Tooth app on the batteries is indicating about 50% reserve remaining with each of the four batteries getting about 5amps respectively. What I really like about the technology is the discharge curve. At 50% they are maintaining a solid 12.5 - 13.0 volts. Lead acid would be at or below 12V by now on their way down to 10V or less. There is no dimming of the lights or low voltage warnings when I increase the load by turning on my microwave or a heavy 12 volt draw like the furnace cycling on. The Blue Tooth App has turned out to be a pleasant surprise. I thought it would be more of gimmick but the app allows you to view each individual cell (four in total) on each individual battery. The geek in me loves having the ability to view the voltage of each cell down to three decimal places. This will come in very handy going forward if I develop a problem with a battery allowing me to determine which and/or how many cells are dysfunctional. I bought the self-heated batteries as we often use our RV in the winter (-20 or lower) and I wanted to have a self-regulating battery charging system. Now I don't have to worry about designing a method of monitoring temperatures and cycling battery heat when required. With our PV panels constantly in the circuit, my having to build a 12V heating system for the batteries to warm them up before they saw the solar panel current would have been a huge pain. Additionally, externally heating the batteries would be far less efficient compared to the Lossigy's method of heating them internally at the cell level. The cost for self regulation/protection was well worth it to achieve that benefit and the related piece of mind. Now if something happens related to low temperatures it is Lossigy's problem not mine. All in all I am very pleased with the batteries and in particular the Blue Tooth App. The only remaining review parameter is their longevity. That will be a four or five year journey.

I purchased (3) of these Lossigy 12v100ah batteries for my 1990 Ezgo golf cart to replace the (6) old lead acid batteries. Once installed they were awesome!!! These batteries are powerful, delivered consistent voltage for hours between charging, and much lighter. My golf cart had more power and speed than it had in years, maybe ever. After about 3 weeks of great performance the BMS tripped out on one of the batteries while I driving up an inclined road, and my golf cart just died. I emailed Customer Service, I found the email on the warranty and service agreement on the last page of the product manual. A Service Rep (Jenny) responded back very fast within 24 hours. Over the next day or so she helped me trouble shoot the issue. It turned out that these batteries only have a 50A max continuous discharge current output, which I didn’t notice when I purchased them. I have many incline streets in my neighborhood, and when I was going up one of the bigger inclines the golf cart was pulling more than 50A and the battery BMS safety tripped out. Jenny concluded that these batteries were not going to work for my application. To resolve my issue Lossigy offered to take back all (3) batteries and up grade them with (3) 12v 100Ah-Pro, which has a 100A max continuous discharge output, at no cost to me. At the time when my battery died I was concerned I would be without my golf cart for a month or more while resolving my issue and getting a replacement battery, but Lossigy Customer Service had my issue resolved and the new batteries at my front door in less than a week. The new batteries are installed and working great. My golf cart has never ran so fast, even going up the inclines with passengers on board. Therefore, if you are looking for a Lithium battery to replace the lead acid batteries in a golf cart Lossigy is a great choice, but get a battery that has at minimum a 100A max continuous current discharge like the 12v 100Ah-Pro. From my experience Lossigy batteries are a great value, they are light weight, beautifully designed, built very solid, long life expectancy, great price, and Customer Service is out of this world!!!

I use the batteries in my golf cart. Longer lasting, better performance, and lighter weight than lead acid batteries. One of the batteries initially failed to hold a charge after a couple months of use, so I contacted Lisa in customer service. She had me run a couple of tests on the battery to determine the problem. She had me send the faulty battery and they promptly replaced. No more problems! Fantastic customer service!

Great battery for the dollar! In terms of value this is a 5 star all the way. Good build quality, decent BMS, and so far after around 8 months of use I'm not seeing any weird issues. I did knock a star off as I'd really like to see the continuous discharge at 200 Amps. Many competing 200AH batteries offer a higher continuous discharge for around the same price. 100 Amps sounds like a ton until you realize that if you're running an inverter that is going to translate to only 1200 watts or so. All in all a good purchase, But I may be moving to Jita for my next LFP.

I'm enjoying this battery. It works well and I haven't had any problems with it. I would buy this product again.
