if i put in 12 modules per pack, i could have four modules per center tap bus, and 21 chargers. but the .1 amps per module is not going to charge much.=C2=A0

at 4.1 volts, they put out .4 amps and red light is still on.

at 4.16 volts they put out=C2=A0 .25 amps

at 4.18 the light turns green and they drop to .1 amps

will leave on for a= few days, but not doing much at .1 amps

when charging a ban= k of four modules, doubt the .1 amps will do any damage if left on for weeks. .
