12V 50Ah Lithium Battery, Rechargeable LiFePO4 Battery with Built-in 50A BMS Board, 5000+ Deep Cycles, Perfect for RV, Solar System, Fishing Boat, Camper and Off Grid Applications

Holds its charge, is light,and is reliable. I use it on my 10 foot kayak for range and time on the water.

Great little battery right here. We purchased 4 of them just to try them out and they are light weight, come charged, and so far doing what I need them to do. I will be buying lots more of these.

Great buy. Good quality and last for hours with my 35 lb thrust trolling motor

Capacity started declining after only 2 months and kept getting worse so at 4 months usage I stopped using it for a while, I started up another usage period when battery was only 7 months old and capacity was much worse after sitting, i contacted seller for warrantee and after i did extensive load testing and sending them displays of load tester results they said nothing is wrong and its normal for battery to do what its doing, I said its not normal for resting voltage of 13.6 to drop to 13.0 after only 1 minute of small 10 amp load. This battery at first supplied power for much more time while holding 13.4 volts, then it dropped short time later to 13.2 volts, then at 7 months old it went to 13.0 volts. For a $200 battery I would at least expect capacity to make it to end of warrantee period of 1 year. I had a feeling these people were just playing with me when they kept asking stupid questions, then they finally said they are not doing anything. Not a happy customer and will never buy from them again. Update : customer service decided to send out replacement battery if I paid shipping after I showed them tests results showing a defective battery. This was appreciated and I am happy customer again. I only gave 1 star at first but I am giving 5 stars for doing right thing and replacing battery. Thank You ...

DON'T buy anything from these guys. The battery didn't work for me, and they made me pay $48 to ship it back to them!! More than half of what I paid for it. Never again

Love the battery I've been replacing My RV AGM battery every single year Spent so much money Because I always forget to disconnect it over the winter , it drains battery It's simply die, and won't recharge This new lithium battery has a low voltage system disconnect it won't go below zero Love it If you drain the battery down, it's gonna disconnect from RV and then all you need to do just plug into the shore power, and it will start recharging again I also bought small 200 solar Panel couple hours every morning it recharges again It's plenty of power through the night Because you can drain the battery I believe down to 85% Compared to AGM battery only 50 or 40%

I purchased two 12.8v 50ah batteries for my 24v trolling motor. I have had zero complaints. They have been work horses,and lasted for 3 days of prefishing in high winds on a single charge. The other night i backed the boat in from a long day on the lake and plugged them into charge when I noticed my charger was throwing a code saying it was not charging. I have tried everything to get one of the two batteries to take a charge and it will not. I’ve been trying to find a way to contact the seller with no luck. (Any help would greatly appreciated) this is not a bad review things just happen. I just wish I could have gotten a little more out the one battery.

This was purchased for use in an old Vector PoB HID handheld search lantern that took the standard 12V 7AH gel cell batteries. It fit perfectly, same dimensions as those old batteries but is much lighter and with more capacity. The built in BMS allows us to continue using the original charger that came with the lantern. We have tested the unit and while we have not run it down, it is clear that it will run a fair amount longer than the old gel cell could do.
