[QUOTE=Milo.1976;9796319]. I have no idea about batteries eg/ what 5000 mah 40 c QUOTE]
The 5000 Mah is the amount of energy the battery holds 1000 mah = 1 amp. so that battery mentioned above holds 5 amps. The C rating means how many times the capacity power you can safely pull from the battery safely. 5000 \ 1000 = 5 amp. 5amp x 40 = 200amp. Your battery should be able to safely supply 200 amps with out damage.
