First one lasted under 2 years. It hurt knowing the $280 batt was done. Luckily I had already bought another at a discount so I wasn't ski less. So I bought yet another one so I'd still have a spare. I sorta rotate them 2 into the ski. Been 4 plus years now. Charge after every ride, about 5 gallons worth. Unless at the beach then 10 gallons. Remove from ski when charging or not in use. I use the anti gravity charger or whatever brand it is. It doesn't need such frequent charging iam just trying to stay well above min voltage.
That battery box I modeled out of cardboard, it's sized around the anti 16 cell battery, so without really realizing it I limited myself to that size battery, I sent the model to Steve at the Watercraft factory in Florida and he made it out of glass for me.. I made the mounting set up and held the strapping set up.
I didn't mention the anti brand in this thread cause every body already knows about them. I have a buddy that trashes these battery's. Over discharges, incorrectly changes, crosses battery terminals. Another buddy bought a different brand and was his first lipo..... I spent a lot of time convincing him to get the recommended charger... But when I told him to disconnect it when not in use or when storing over winter so you don't accidentally drop below min voltage he declined...
