Question about LiPo battery pack

[sjoerdvdd]

Hi!

Finally decided to go with the turnigy LiPo's for my project. But still, i have some remaining questions.

for the record, the battery is going to be a 96V 45Ah LiPo pack. based on 2s1p hardcase trunigy cells which are 7.4V 5000mah each.
turns out i need 120 of these packs.

next thing to do is charge, balance and monitor these cells ( very good! because of short circuiting, low voltage, or overcharge. )

the pack is build up from 13 packs in series, then 9 packs in parralel.
does it mean that i have to have 120 BMS modules, LVC modules and ( based on a Icharger ) 12 chargers?! when i want to charge each cell seperatly? since an Icharger can roughly charge 10 cells at once.

and is BMS and LVC both nessecary? or can i just only one of them?

can someone explain this to me? and tell me exact how many BMS, LVC and chargers i need to succesfully and most important safely charge and discharge this pack?

Thanks in advance and sorry for my bad english

Regards

LVC means low voltage cutoff. its a function of the BMS, or the controller, or both.
you don't need a BMS for every pack, but you do need 1 BMS channel for each set of parrallel cells.

That's ALOT of lipo ... what's the application ?

Hmm allright, so that means i need a 9 channel BMS?

and anybody any info on the charger?

Application is a pretty high end motorcycle with performance comparable to the original ( KTM 525 )
