KEPWORTH 36V 100Ah LiFepo4 Battery, Rechargeable Lithium Batteries with 200A Bluetooth Smart BMS, 4000+ Deep Cycle, 10 Years-Lifetime, Perfect for Boat, Trolling Motor, Golf Carts, Lawn Mower

Been using this battery for about two months so far very reliable never had an issue. I love the fact that it comes with an onboard charger. You can just plug it into the wall charger and go. We’re using this on a diesel pump. Battery life seems pretty good but have never drained it all the way worth every penny highly recommended.

Purchased to charge RC batteries in the field. Plenty of power to charge many packs before it needs to be charged. Comes with charger, does take a long time to charge so you will need to plan accordingly.

This battery works really well. It runs my lights and my depth finder. If you need a phone charger the one built in works good it's not like the fast chargers but it will get ya some good charge to your phone.

Great battery and very easy to charge. Lightweight and perfect for my trolling motor. Last all day while under almost constant use. Best price for one of these batteries.

We bought 2 of these. I love the USB access ports (2 on each battery) to easily charge my phone. Customer service is great. One battery did not work on arrival (issue with faulty FedEx delivery) where it was dumped on its side out in direct sunlight on a 90° day. Customer service quickly responded, gave the battery a rest to reset the BMS and all is well now.

I bought this battery to replace a lead acid deep cycle battery that had died. This is about half as heavy and similar power specs. I use this primarily for a 12 volt water pump for irrigation, and for running tools via an inverter. I used it to run a large fan outdoors on high power and the battery lasted 2.5 hours before it needed to be recharged. The battery still had 11.5 volts. The supplied charger brought it back up to full voltage.

No GD instructions with the GD charger!Used it one time for trolling motor and it did fine.I ran it dead which is fine.I plugged the charger in to the plug in port.Do I push the provided button?Who knows? They send ZERO instructions with the battery/charger concerning the power button, the usb ports, the carger, how long it takes, how do you know if it's done charging.Does the red light turn green?It's been plugged in 12 hours now and I'm getting nervous about it being plugged in that long.Do you push the GD button to get it to take a charge pr just to use the usb ports?I am furious over the lack of charger information.

Better than you think, I know no one suggest to use it for a starting battery, but I have a 70 hp Yamaha and it works great. I do 7 hrs fishing tournaments each month. My boat starts, gps and all extras stay in with engine off. Has never hesitated to start. Love their battery's. I also have 2 smaller ones for trolling. I used to run out of power by days end. I haven't been able to drain these less than 25%. I come home after all day and have 75% left.
