R/C Tech Forums - Help choosing batts for 150A system

Hi guys,

Only just getting into rc recently with my kids and bought an e-revo brushless for bashing and maybe some casual track every now and then

got it 2nd hand, it was in bad shape. have decided to overhaul it with new bearings, whatever needs repairing/replacing, and a new motor and esc.

just bought a hobbywing combo quicrun 8bl150 with 4074 2000kv motor. 150a system. Gearing will be 18/54 maybe 20/54 once i see how temps are.

Question is about running the 2 batts in series (which is how its setup currently). Have done some research and found that C never changes, but im still not sure about the continuous amps. Dont want to spend more than i need to on the batts...

This battery GA2S-5300-30C-S is rated at 159a max continuous current, which means it has 9a spare if the system is at full load if i understand correctly. Not sure if it will ever get to 150a though? So do I get 2 of them if run in series, does that double the max cc (318a)? Or do I get the cheaper one that is max 100cc per batt?

Cheers
