Coming back to this issue. Need to know if the KS18 can be wiped from my favourite list. Are the batteries connected in series while charging (BMS) only or are they in general in series? I thought they had parallel packs. I never opened one.
I'm a heavy rider so I need power from a dual battery pack. As I rode a KS18-500 only up to now I can't do a real incline test as it's not strong enough for me to be pushed like a MSuper.
Dmethvin,
Yes you are understanding wrong (although your post immediately above this one suggests you are understanding now?)
The video you link to is excellent (and recommended viewing for anyone trying to understand why we need a BMS).
As shown in that video. BMS does not charge cells it discharges them ( or more accurately with our BMS prevents them taking any more charge.
Also, in that video, all charging is done via the discharge lines, there is no seperate charge lines
