12V 300Ah LiFePO4 Battery, Built-in 200A BMS, 15000 Deep Cycles, 3840Wh, Low Temp Protection Lithium Iron Phosphate Battery for Home Energy, RV, Trolling Motor, Marine, Solar, Off-Grid

I highly recommend this battery and seller. I ordered one, tested it on a load of 850w continuously running an inverter directly off the battery and it performed flawlessly. I recharged it and added a battery monitor. Both working well. I decided it was so good and such a great price I would order another one. The seller responded promptly regarding my request for a battery compatible with my batch (it was mentioned on the manual). They also partially refunded me for the first since the price dropped only a few days after I purchased it and bought another. Very respectable seller!! I highly highly recommend! I may buy two more to wire them in series and parallel for a ~15kWh backup storage at 24v. But we’ll see how this second battery in parallel goes first.

What really impressed me is the fast charging and deep cycle performance. I’ve run it through several charge/discharge cycles and it’s performing like a champ with no noticeable loss in capacity. Plus, the built-in BMS gives me peace of mind knowing it’s protected against overcharging and deep discharges.It’s also noticeably lighter than traditional lead-acid batteries, which is a huge plus for my RV setup. For the price, performance, and reliability, this battery is a total win. If you’re looking to upgrade your power system for RVs, off-grid cabins, or backup power at home

I live off grid and have need of electrical storage solutions, which this battery provides quite nicely. I use it connected to a 500w inverter which powers my satellite modem and computer most of the time, but I use it for other things like my sewing machines, external drives and cordless tool charger etc., whatever the 500w inverter can power. I also use the battery to power a 12v water pump and this coming winter I will also begin using this battery to power my 12v diesel heater as well. Eventually I plan to upgrade the inverter to 1,000w which will expand the range of devices I can power with the battery.So far the battery has worked flawlessly. It has a lot more capacity than the lead acid batteries it replaced that had similar Ah ratings. This thing just keeps going and going. It charges quickly with no mess no fuss and no ventilation required. It truly is quite amazing. It takes up a fair bit of space, but is smaller and far lighter than the pair of lead acid batteries I used to use.This battery was about the same cost as a pair of 100Ah lead acid batteries and was a no-brainer to switch over to the 200Ah LifePo4. I did have to invest in a new charger which in the long run is insignificant. I think it's a terrific value for the money and I'm very happy with it.

Just connected the batteries and so far they work as expected. I'll update after a year. The company is good too, there was a mistake with shipping and i ended up waiting an extra few days for the batteries, but they made it right and it worked out in the end. I do wish that the support wasn't 12 hours opposite of the US though, that just costs time when trying to resolve issues. All in all, i'd recommend the batteries (300 ah) and the company.

I have purchased 4 100 AH Rvpozwer batteries. All perform well. All charge, discharge, recharge,... perfectly.I recently received a 200 AH that will not hold a charge. It came with 11.2 volts and, after three days on my Noco Genius charger and another day on my MPPT, it remains at 11.2 volts.Edit: Contacted customer service. Demonstrated defect and they've offered a full refund/replacement. I cannot ask for more than that.

Purchased this battery as part of a put together battery back-up for a sump pump.The battery arrived at a little over a half charge according to the sine-wave power inverter I purchased. The sump pump pulls around 677w at peak per cycle. I've done a few test runs to ensure the set-up runs fine. So far I have no complaints as the battery is holding a charge well and is on standby for our next inconvenient power outage. I believe my power inverter took about 4 hours to fully charge from about 70%.I purchased a group 31 plastic container and the battery fits well. It's not incredibly heavy in weight for its size. It also came with a strap and an extra that can be added.

Firstly I would recommend this battery despite my initial problem. When I first received this battery I checked the voltage and found 0.2 volts. I got nervous when I discovered I couldn't return the item and could only contact support. The support was GREAT. I sent them a picture of my voltage reading and provided the battery charger I would use to charge it. It didn't accept a charge and they sent a replacement quickly. The replacement worked great and I couldn't be happier with the battery and support

Great product at reasonable price.
