Charter approved
Haven’t had the battery long so I can’t talk on life span of battery yet. But I can say the battery and customer service have been amazing so far. Had a couple questions so I scheduled an appointment on line and nick called me up with in 10 minutes to answer all my questions. I ran four consecutive charters on one charge without dropping below 20%. Probably…
Perfect for trolling motor applications
I installed the EPOCH 24 volt 100 Amp hour battery on a 19 foot Sea Runner aluminum boat to run a Minkota Torrova 80 lb thrust electric trolling motor. Very easy to install and secure with the provided hardware. Has been working flawlessly. Excellent product This is a YouTube video I made about the product https://youtu.be/2Mo-640LKlE?si=-sdDHlJnQzVbAovy
24v 100ah battery, simple 24v system
Absolutely love this for a trolling motor setup, much more battery than I need and could likely run it two days ... great versatility and no worry whatsoever on battery life 👌
