bike comes with 10ah and 14ah batteries in parrall@48v
I only did the math, based on the specs and assumptions. Neptronix added his layer of wisdom and experience.
He advises 1/4 of the rated current is safer for the battery, and maintains better performance by not sagging. I used 8A per cell in my calc, which is supposedly the continuous rating, although oddly stated in the data sheet. The data sheet is ideal, and won't take into account how the pack is configured or dissipates heat, etc.:
8,000mA (for continuous discharge)
13,000mA (not for continuous discharge)
You can draw your own conclusions and decide how much to beat up your pack. I have 8P of 35E cells. It gets hammered off the line, but not continuously (I still like pedaling and don't ride fast), and I'm OK with the consequences.
1/4 of 56A is
14A. (if using the peak rating from the data sheet, 1/4 would be
23A)
For 1500W continuous at 48V you need at least
31A continuous battery amps even before taking into account losses. The motor will probably pull 3 times that or more if you let it and don't have the controller limiting current.
