LiTime 12V 300Ah LiFePO4 Battery, 200A BMS Rechargeable Lithium Battery with Up to 15000 Cycles, 3840Wh -Higher Energy Density, Perfect for Off-Grid, RV, Solar, Motorhome and Boats.

The other professional reviews I have seen from this outfit show that they make quality batteries.I have a variety of uses for this battery:1. A lot of 12V devices that plug into your car are now 12/24V capable, granted you need to check before buying. You go camping somewhere or just need power on the go and with the right cabling, you can plug straight into this battery. USB chargers. Portable fridges. Laptop power supplies / USB-C PD, etc.2. You can plug in a high powered inverter and it will need much smaller, cheaper, and easier to work with cabling than with a 12V inverter. This battery can easily push even your most demanding 120V AC devices through a power inverter, granted you want to keep the power draw from the battery at 100A or less.3. If you have any outdoor hobbies needing power, say flying around an FPV drone, you can hook a hobby charger straight into the battery. Especially high powered hobby chargers work a lot better off of 24V than 12V. Actually, running a hobby charger was one of the big reasons I went to using 24V in the first place over 12V.4. It turns out a lot of electronics even if they don't have a USB-C PD port, they still run off of something like 24V DC. You can get buck-boost regulator converters for a steady 24V output (or whatever you need), and especially when the voltages are close, the buck-boost converters are extremely efficient and compact. 24V to 12V converters are also pretty efficient.5. For emergency situations, a battery like this hooked up to a power inverter can run a modern fridge all night long (or all day long), keeping you from having to run a generator non-stop or just waiting out a storm with an unpowered fridge because it is too stormy to run a small portable generator outside. Maybe you periodically fire up the generator to recharge the battery.6. The battery is easy enough to carry around and stick in a car, helping to give it wide range of applications.

Great battery, super light and super functional. Use the battery on my Pelican Bass Raider running my Livescope, Trolling Motor and brake stop. Unbelievable the lightness of this battery, weighing just a few pounds but packing a punch. If you are looking for a solid lightweight alternative battery to the super expensive battery's in the boating market grab one of these.

I’m super happy so far with this battery! Considering the power, it’s very light weight compared to a lead acid battery. I’m using mine as a portable power station with an inverter and a couple cigarette lighter style outlets for when the power goes off here at home. Only took a couple minutes to install everything using Velcro and some zip ties. My charger has a 10 amp charge rate and filled me up in a few hours. Next time the power goes out around here. We will at least be able to run a few AC things and keep our phones charged up, for way less than buying fancier pre made power station

I have been using this battery for several months and it is working great.However there is a flaw in the app that monitors the battery.If you are simply opening the app and leaving it connected to the battery via Bluetooth you are getting a false reading.You must disconnect the battery from the Bluetooth and reconnect before each ise to get a proper reading of your battery .If you don't do this the app will say you have plenty of charge remaining but your battery will go dead and could damage the battery.

This packs 1.28 kWh of power which is quite good, and it doesn't weigh too much either, ~20 lbs. Beware tho that they shut the BMS off for delivery, so many chargers will not recognize it. It showed up reading only 2.8 V and my charger would not recognize it. You must have a charger that will go from 0V OR, like me, I had to jump start it. I had to get some voltage on it for the charger to recognize it was a battery. I did it with a male cigarette 12V connector to bare wire connected to the battery, which put 13+V on the battery. Then, it charged right up. It could be done with regular jumper cables with your car battery too. Or, as mentioned above, it can be charged with an expensive charger that will charge from 0V. Now that it's fully charged, however, I should not need to jump it, unless the voltage runs way low again.
