MGM 12018-3 car and A123 cells

[gyn77]

Sometimes I'm using 7s1p for light weight setup and sometimes 7s2p for high power setup.

My motor is a Neumotor 1515 1700 kv and with 7s2p my savage is a monster of power!!!!

I would like to add a cell if the MGM 12018 could accept 8s, but I don't want to fried my esc, so I must be sure if it is possible before trying.

Also I'm thinking to get a MGM 9032 for using 10s1p A123, but I don't know if my neumotor will be ok running about 50.000 rpm.
