Sorry, forgot to mention all three packs are smc 35 amp matched.
"i got unmatched packs, and i get 400 secs of runtime at 30 amps
and the voltage is a bit higher than yours ;/"
How many runs on your packs, mine are at 15.
Dont get me wrong in no way am I trying to imply the ib3600's are awesome cells. So far they seem about average with my crap old gp3300's which really is'nt a good feeling after shelling out $128 on them
