12V 600Ah LiFepo4 Battery Rechargeable Lithium Batteries with 200A BMS, UP to 5000+ Deep Cycles, Perfect for Boat, Marine, RV, Solar, Trolling Motor

These are probably one of the best batteries you can buy at this price. I have purchased six (6) of these. Simple. Reliable. No frills. Compact and light weight. I have three in series in a 36v golf cart and it runs for 10 hours on a full charge. I have three in parallel in my 12v RV and with conservative use they will run my RV off grid camping for 3 or 4 days. Awesome. Maybe others are just as good. But I doubt you will find better at this price. I only ran them down one time. They really give a tad more than 100Ah at least when new they do. Nothing bad to say.

Battery is very lightweight wholes a charge a long time

I bought two of these for my genie manlift, which do not require heavy duty, cold cranking amps. And so far so good. They have been working great and they’re very easy to charge and best of all. I do not have to do any maintenance and they are much more lightweight Than lead acid batteries. Of course, if you decide to use these for a scissor lift or a different type of manlift be sure yet you compensate and add the weight that is required because some of these machines require a certain amount of battering weight for stabilization. That does not apply to my One man genie manlift.

The battery was supposed to arrive on 2/9/2026. It arrived today 2/5/26. I checked it out for proper voltage and put my battery charger on it and in 15 minutes it was fully charged. 300 amp hour battery would take much more time to recharge. This battery will come in handy camping or for emergency power to power my Ham radio if power is lost. The battery is very well built and not nearly as heavy as my 125 amp hour lead acid marine battery.

I charged this battery with a new battery charger for LiFeP04 batteries with BMS, connected it to my RV and ran some lights. I had no more than four lights on (all12v automotive type LED bulbs, 2 watts each) at once, for no more than three hours. Then I turned all the lights out and went to bed, five hours later when I got up, this battery was deader than a door nail, (or the BMS shut it down for some reason), and it took all day and half the night to bring it back. Now I have run those lights for three days on a garden tractor battery that is so bad it won't start an 18 hp garden tractor, and I haven't tried the battery a second time yet, but first impressions tells me it is a piece of (non-returnable) junk.

I can't say anything about long term longevity yet but the capacity rating was accurate. It seems to shut off somewhere around 9.5 volts. That seems a little bit low. It should be 10v. Also the low voltage cutoff seem to re-enable the battery after a few minute then cut off again. I haven't experienced this with any other LiFePO4 batteries I have tested. Usually you must charge the battery first. I won't give this battery a perfect rating but it seems to be acceptable quality. I didn't attempt to test the other protections.

These are excellent batteries. I bought a pair. Although they are not rated as starting batteries, either one could deliver more than enough current to start my 60 hp Mercury outboard (they spin it like a top!). Seem to at least meet their ampere hour rating.

I got two of these 24volt batteries to replace the four 12 volt lead acid batteries on my Ryobi rm300e mower. They last longer than lead acid and have more useable amp hours since they can cycle deeper without harming the battery. I put them in with the terminals on the side instead of on top. My understanding is that lifepo4 batteries are ok either way. I did not have to modify the mower in any way. For the first time, I can finish my entire acre without recharging and still have plenty of extra charge. I am happy so far.
