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.

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.

These are excellent lithium batteries. I put two of them in a Ryobi electric riding mower and they worked perfect. They lasted nearly an acre and will go longer after a few charges. They have excellent connectors and were easy to install. Make sure you use the correct charger fore lithium batteries. These would work great to power a trolling motor or a standby power supply. They are an excellent value.

Replace an wet deep cycle battery with this battery and first time out was not impressed. But it was User error, I did not get fully charged, once it was fully charged it lasted 12 hours longer with out being charged. You need a battery charger that has a setting for LifePO4 battery. Otherwise you'll never know if is fully charged.

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.

So far works great I have used s power meter on it and drew it down to half capacity using a 54 pound trolling motor on full for about an hour at about 50 amp so I believe it is good for the 100 since it was holding voltage well.

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.

So far it has worked just fine, I have not done any heavy lifting with it yet though, and the real test will be how long it lasts.
