Epoch V2-T

If you really need to depend on your battery in the middle of the ocean or far from civilization, use these. This companies batteries have had the best hardware from day one. The first versions of this battery had some software issues, but now they have made a unkillable battery. I have cycle tested it, max load tested it and tested all safety features and it works great. One of my friends is running it in his truck as a starter battery (not recommended by the company) and he hasnt killed it yet. This brand also makes golf cart batteries that I have been running in my golf cart daily for five years without a single hiccup.

If you are worried about security risk of bluetooth batteries, this is the battery for you. You can remove the bluetooth antennae because it is located in the SOC meter! Most batteries do not have this design. If you do not want a security risk possibility, remove the soc meter on the epoch and you are good to go.
