That's a good test bed for it.

I think you'll see, they don't mind a big amp load at all.

My 2S2P packs went through some more testing today.

This time in an E maxx using a Novak HV Motor powered by a MM Pro.

The MM Pro is smooooooooth in sensored mode.

What I did different with testing was:

Using an AUTOMOTIVE type charger, which yields a 14.5 volt charge cutoff, I recharged the packs in series, at 20 amps!

The entire recharge took less than 20 minutes! I did monitor cell voltage with a meter while recharging.

They didn't mind this treatment at all. The packs were cold when the charge cycle started, and cold when it was done.

I was tempted to kick the charger up to 40 amps. Hmmm.......should I try it?

40 amps would be about a 9C charge rate.
