Soon I will have 2 LiFePO4 (48V) packs on one of my bikes with the discharge ports connected in parallel. One pack is 14ah and the 2nd is 10ah.

Is there any problem with having the charge ports on these connected in parallel and charging these packs together simultaneously with one charger?

Someone told me I shouldn't because they have different ah ratings, but it seems to me the BMS on each pack will manage the charge going to each, and the charger will just continue until the "average" voltage of the 2 packs reaches the cut-off point (i.e. both are fully charged).

Anyone have any experience or even theoretical feedback on this?
