Since LiPo's are charged at constant voltage, if you were to make a harness
with perhaps 1/2 Ohm between each pack, would it be possible to
charge/discharge multiple LiPo's in parallel?
For example, after returning home from the field, connect all discharged
batteries to a parallel adapter connected to a balancer. The adapter
would
have small value resistors to limit the current between packs since they
are
most likely not discharged to the same voltage. If you aren't going back
to
the field until next week, set the charger to charge to storage voltage of
approx. 3.8V per cell. Then start the charge before the next planned use.
Advantages: All packs are stored at storage voltage and all packs are
charged to be ready before use. Use a single charger on multiple packs.
Need: Mating connectors for balance plugs and ~ 1/2 Ohm resistors to limit
current in case you throw in fully charged pack with discharged packs.
Fuses or other current limiting devices would be needed if you might
throw
in a discharged pack with multiple charged packs.
