Battery capacity

[jerry m]

Hi All,
Whats the correct way to measure the wattage of a giant energypak frame type battery?
The actual battery has 5 female contacts so wouldnt have a clue which are used.
Originally the bike was 375w but the lbs says they fitted a 500w one under warranty, but i havent noticed any difference.

Wattage is calculated, not measured. Voltage x Current = Watts.
I’m not sure of the connection configuration of a Giant battery. Sry, can’t help any more than that.

I can interchange a 500w battery for a 625w on my Trek Rail. There’s no noticeable difference in torque. But there is a difference in time, if the demands on the motor are the same.

Peddle assist is somewhat controlled by you. Mode selection, your energy applied (which can be calculated in watts)to the peddles/motor, duration of torque applied etc. each motor can be different though.

As you, we have both. Use 500Wh in winter but will probably switch to 625Wh for longer summer rides especially when we go to France for our summer holiday late June/early July (before kids break up for their summer break).
