so i was thinking about this but didnt know what the actual end result would be… so,.
lets say I have 2 separate packs both with its own BMS. Lets say one is 10ah and the other is 15ah
now i know for a fact you can link multiple packs in parallel (with same capacity) each with its own bms… and charge all packs off the one input port (assuming the battery shares the same charge/discharge), as Ive been doing it with my ebike with those 2p ebay packs…
so heres the thought…lets say I want to go on some long ass ride (with pnumeis) and I have the 10ah and 15ah paralleled. I assume once the 10ah gets depleted first (which it would) the bms hits LVC and shuts the pack off.
Does the other pack keep working? Does the vesc recognize some sort of LVC from the BMS and refuse to work? Similar to if you were charging packs in parallel that werent charged from the same starting point…the first one to hit full capacity will trigger the charger to stop charging…
I was assuming the first pack cuts out and the board dies over all, then you could unplug the dead battery… and the 15ah will continue to work with what ever juice is left. Dont worry about the actual logistics of getting the wiring to be easily accessible.
