12V 300Ah LiFePO4 Battery, Built-in 200A BMS, 18000 Deep Cycles, 3840Wh, Low Temp Protection Lithium Iron Phosphate Battery for Home Energy, RV, Trolling Motor, Marine, Solar, Off-Grid

Perfect for the van . Keeps a great charge .always sitting at 13.03. So theres. No need to worry ant using lights etc ... great guy and with a percentage off at the till 😂

this is a review of the rvpozwer 300ah battery. had it two months now and was initially concerned that after showing 100% charge on the shunt i only got 100ah before low voltage alarm went off. contacted the company and they trouble shooted that it was not getting enough charge from the mppt controller. I didn't have a mains charger to test it with so had to leave it on charge for 4 days to get full charge from solar panels and it is now close to advertised capacity at least 280ah. i have no idea about the quality of cells etc but forbthe money it will do.

Update 12/10/25 I received the replacement battery to replace the one that arrived DOA and the replacement is working normally. I now have 4 working batteries to completed my series and parallel banks for my solar inverter. Receiving a bad battery was frustrating while waiting nearly a week for replacement but the seller did the right thing and was responsive in resolving the issue. So I have to give them the credit they deserve and update from 3 stars to 5 for good customer service. All is good now and hopefully these batteries last as long as they claim. Here is my story. I purchased the first 300ah battery in late October 2025 and used it to power my audio system which is running two 5000w amplifiers, stereo receiver. This battery is operating great and after a full days use of the stereo system the battery only dropped 3 volts from 13.4 to 13.1. Being happy with this I ordered 3 more week of Thanksgiving and decided to use all 4 for my 3000 watt inverter and use a previously purchased 200ah battery from another manufacturer for the stereo system. These were on sale due to black Friday event which saved me $85 bucks per battery over original price I paid for the first one. All was good until the batteries arrived. One of the three was DOA. No voltage whatsoever. I contacted the seller which responded within a day and as instructed provided them with a picture of the voltage reading I was getting from the battery. Within another day they responded with a list of instructions on how to wake the battery. With this I become frustrated because frankly who has time to be playing around with something brand new that does not work. I demanded they either take it back and send me a replacement or refund my money. They won't take these things back due to the cost of shipping hazardous materials within the battery. Within another day they responded they would send a replacement. Within another day I received a tracking number but the replacement has not shipped as of yet. As days are passing by I decided to go through the steps they provided and applied 8 volts with a regulated bench top power supply for several hours. Still nothing, battery would not wake and no current was being drawn into the battery. I then tried applying different voltages and still nothing, just dead as dead could be. Because I do not have four batteries to make series and parallel 24v supply to my inverter, I'm currently using one bank of 2 connected in series. The two working batteries seem to be functioning as normal and running at 50% load for two hours voltage drop has been minimal. They also seem to charge back up to capacity quickly. At this point so far I'm happy with 3 of the 4 batteries I ordered, although they have not been in use long so I can't report on longevity. I also have to give credit to the seller for at least being responsive and attempting to rectify the situation although I'm not particularly happy that days and days are passing by and I don't have a working battery as of yet. With that at least know if you do have a bad battery the seller is upfront and responsive about resolving the issue. It would seem to me that the problem with these batteries, from reading other reviews is in the BMS, perhaps some are good and others are faulty. I will report back after I receive the replacement on performance of all four batteries after heavy use. With that I will either upgrade or downgrade product rating.

La batterie a mis environ 2 a 3 jours pour ce recharger avec mes panneaux solaires de 200W dans l'ensemble elle est équilibré légère et lourde ça ce porte correctement de plus elle a l'air d'avoir une bonne capacité a voire sur la durée de la batterie maintenant j'ai acheté a part sur amazon des petites borne a visser afin d'y installer des cosses adapté dessus

Bien
