Is my battery ruined? How can I charge it now? 2 weeks ago one friend of mine tested it and it has juice to move the bike (it was fairly charged when I left it).. I assume it does not charge now, only the 1 red led turns on in the charger when plugged.. Please help, it was really expensive to get one here, and I so pissed with myself for forgetting conditioning it while away...
My 48V, 8Ah Li-ion from Ebike C.A. is now R.I.P.
I was shipping the bike home from from a sm. island in the Caribbean where is was working and although I knew it would sit for a while, it actually sat at the origin warehouse for 3 months. I had discharged to about 50% for storage[i probably should have taken it up to 100%, although I doubt it would have helped]and i think the heat, as much as the time period, killed it[bike in box, box in warehouse on tropical island].
Upon arrival, it tested 0 Volts. I dis-assembled it and ck'ed at the parrallel/ cell level, 0 Volts. Dead as a door nail.
In retrospect, I should have sent it Air Freight. The problem with sending it on the "slow boat", is that one can't carry these batteries on an airplane, so the batt. cond. is going to be out of your hands for a while. Or better yet, don't ship Ebikes overseas.
I was more than happy with the Mxus mini-motor on 48V, so I'm interested in how this pack performs for Rassy. My FS bike has an open triangle and the Falcon EV bag fits nicely. I also have one of Johnrobholmes's Mini Stealth[25A version] controllers to try out.
