    888 total miles, weatherand wrist injury slowed me down... new battery has 100 miles now and seems just like OEM so far. I finally aquired a Silverfish case only (no batteries) in addition to the complete battery. I Made a mistake by not purchasing from the same vendor as the complete Silverfish...

    Hey Clueless, thanks for the info... so you're saying to charge just before riding to 100%, my charger has a red/green light only, impossible to tell 90%, does yours have a digital readout? I've been charging right after the ride, Maybe I should leave the battery low after the ride and then...

    Ecotric Hammer Fat tire bike

    Thank You harryS. Just that one word, 'silverfish' was the key I needed. Feeling much better than $400 now. I was also missing that fact that it was a 'generic'. Now I got some digging to.

    Ecotric Hammer Fat tire bike

    I understand, cold bad for batteries, but I live in Oxnard CA. Lowest temp when riding is upper 60s. Highest temp was mid 80's. I've dealt with Ecotric tech support before when the PAS stopped working and it was not a happy ending. Tech support basically said they don't support PAS anymore...
