LiTime 12V 50Ah Plus LiFePO4 Lithium Battery for Trolling Motor, 50A BMS, 10 Years Lifetime 4000+ Cycles Output Power 640W, Perfect for RV, Boat Marine Trolling Motor Camping

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.

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

Bottom line up front: This battery is pretty awesome on it's own; it's amazing for the price.First, LiTime's packaging is on point. The battery showed up in a heavy duty box well protected by foam. Even the package smashers couldn't damage it.I'm using this to power an ARB Classic fridge and a Puma PD1006 compressor in my truck. It works great in this application when paired with a quality DC to DC charger and solar controller. I'm using it with a Redarc BCDC1225 so the alternator and solar charging are all in one, which is nice. The Puma PD1006 compressor draws 30 amps when running; battery handles it like a champ.The Bluetooth is functionality is great. The range on the Bluetooth is much better than most other Bluetooth devices. I can be 50+ feet away with the battery in a covered truck bed and check the status.The app is just "okay". It seems to work flawlessly when monitoring the battery when it's not being charged, where it gets glitchy is when monitoring it while charging. The app will not update the battery status after a while, requiring you to disconnect from the battery and reconnect. Then it works. Outside of that, it works good at monitoring the power going in and out of the battery. The app gives a rather annoying notification whenever you lose connection due to going out of Bluetooth range. If LiTime fixes the battery status update issue, the app would be solid.Overall, recommend this battery if you're looking for a quality LFP battery at an affordable price.
