50Ah 24V LiFePO4 Deep Cycle Battery

I am very pleased with this battery. I have had it for 6 months and it is great. Very reliable, zero maintenance. I have it hooked up to a 300w solar system on my camper van/RV and it charges very fast. I even hooked it up to a 450/900 watt space heater and ran it for 1.5hr on the lower 450 watt setting via a 600w (1200w surge) inverter. It raised the temperate of the RV interior from 55F to 67F in 1 hour (outside temp was 52F with @ 50% humidity in the evening). This was just a test I ran to see what it was capable of. While it did discharge the battery, it performed flawlessly during that time and helped me to learn about how the battery reacts to large loads. The next day I checked on the battery @ noon and it was at full charge from the morning sun. The battery also performed perfectly on a 3k mile, 1 week road trip. It powered the inverter, which fed to 6 LED ceiling lights, a water pump, USB outlets keeping two cell phones, two laptops, one SLR camera, one Dometic fridge running 24/7 without any drop in temperature. Food was always cold. Cold beer in the middle of the desert anytime you wanted. I plan on adding to my solar bank soon with another Battle Born battery and a more powerful inverter so I can run a 1200w water heater and improve the space heater's performance (only as backup in case of extreme cold). I have not contacted customer support yet for any reason but based on other reviews I am confident that area is just as good as the battery itself. I highly recommend this product. Update (2020): My Battle Born battery was experiencing some minor issue one year in. I would lose power for 2-3 seconds once a day or every couple days. The power would turn off and come right back on again. I contacted Battle Born and they said it was caused by the BMS (battery management system) in batches produced around the time I purchased my battery. I shipped the battery back to them (they paid for shipping) and they sent me a new replacement battery which has been working perfectly for 2 years now. Their customer support is top notch as is their warranty. I will not be buying any other battery except Battle Born as my experience with this battery and the company has been excellent.

Purchased one of these to "dip my toe in the water" into lithium for my RV. So far I am very impressed! I will be looking to add at least one more in parallel soon to increase my capacity. First the shipping. It was shipped in an oversized box with plenty of molded-foam packing around it, so it arrived in perfect condition. I would not worry at all about damage from shipping with how well they have packaged it. The battery is then wrapped in plastic to (I assume) prevent accidental shorting of the terminals. What's in the box? Of course the battery, but also 5/16" bolts and nuts. I had overlooked in the description on their site that the bolt set was included, so I was concerned that I would have to figure out how to connect to the terminals myself. But no, the bolt set is included, you're good to go. I'd recommend using cables with 5/16" lugs rather than 3/8" to prevent it from wiggling. I also was able to relatively easily add a terminal-mount catastrophic fuse, although the terminal is a little close to the plastic so I wasn't able to orient the fuse holder the way I wanted it to. Not a big deal though. I am not sure of the state of charge when I received it, but if I had to guess it was around 50-80%. It still had plenty of juice in it to power some devices after installing it, and it didn't die on me after a few days in storage with minimal load. A few days later I hooked it up to solar and it's been running great ever since. The battery is nice and light. If you're concerned about weight in your RV, this is a great way to go. In order to get the same amount of usable capacity in lead-acid batteries, it would have added about 100 lbs. I'm happy that I can now double this capacity for just 30 lbs more weight. I'll update the review if I have any problems, but initial results are positive. While you might get more bang for your buck with a custom LiFePO4 setup complete with external BMS, this is so much simpler as a drop-in replacement for a deep cycle battery. The built-in BMS safety measures (under-voltage, over-voltage, short-circuit, low temperature, etc protection) put my mind at ease too.
