24V Ebike Battery Solution Design Idea
Considering that the customer require 24 ebike battery and energy over 150Wh, then each single battery capacity should over 6.25Ah=150Wh/24V.
It can use Panasonic 18650 3500mAh cell to make at least 2≈6.25=6.25Ah/3.5Ah parallels 7Ah=2*3.5Ah. So the 24V battery should be at least 24V 7Ah.
As the ebike controller rated current is 10A, so it will use a 12A small BMS in the 24V 7Ah Panasonic battery.
