Hi experts,
I have a BH pedelec bycicle with a Panasonic motor and a standard battery pack of 26V x 8A.
After 3 and half years of loyal services I guess that very shortly this battery has to retire
With the Cycle Analyst I can see that the voltage sag is huge and that capaciity is down at around 70%
Given the unbelievable prices that are charged for a spare new battery (around 300 Euro!) this is what I'd like to do:
- buy 2 batteries from HobbyKing Zippy 5000mAh 8S (8 Cell) 29.6V
(weight: 937g, Dimensions: 160x46x59mm)
- then install them in parallel in the original battery case.
My 2 questions:
- do you think that the BMS would be capable to handle this new battery pack (with a total capacity of 10 A instead of 8A) ?
- do you think that the Panasonic electric motor (since a couple of years it's only produced on 36V...), would be able to handle those additional 3 V (from 26 to 29) ?
thanks a lot!
Daniele
