i did not test them. i charged them all to 4.2 and connected them. I balanced every time i charged, and i found that they immediately started going out of balance and over time got worse and worse. If the BM's had kept up it would have been fine, but in the time i had it just wasn't happening. I still don't know exactly why the hyperion keeps them in balance charging them at 48v without balancers.... but there it is.
Thanks for the complement man; I love it for sure, it is everything i dreamed. I am trying to find a 120km/h solution just for fun, but it would take so much power that it would probably be less useful as a commuter. This is a bike that goes almost 100 and can be carried up 4 flights of stairs twice a day
. Batts recharge in about 2hrs, range is about 30-70 km depending on speed/riding style. Life is good.
