All-
I am wondering what opinions the forum might have on using the Thunder AC680 charger (80W/6A) to charge in parallel a 4s2p 10600mwh 30C configuration? I realize the C rate on the parallel charge would be < than 1C (.67C or so I think) based on the limitations of the charger wattage / amps, BUT.... I am actually questioning the potential benefits of having a parallel balance going on with one charge vs charging each 4s1p separately at the nominal 1C rate? I am trying to understand how the two parallel packs would ever be balanced as a "team" when rigged up for use if they were not actually charged togeher in parallel too?
I guess the CON of the parallel charge method is that the charger can only balance on an assumption that no weak or bad cells exist.... given the balance plugs have to be in parallel too right?
If someone just says "buy a second charger for the other 4s pack and quit being complicated" I just might do that as well. No need for LiPo fires in my garage! :confused2:
