new to lipo TEMPS

[C-5Quad]

ok I have 2 new sets of lipos 4000HV 2s1p maxamps and 6400 2s2p by true rc

Im running them in a twin VXL 3905 with 22-68 gearing or 22 whatever factory spur is

on a 90 degree day running hard in a dust bowl motors were 170 esc with fans were 125 and batts got hot as well 123

after a 15min run

mostly running WOT

IS THIS TO HOT??? I dont want to fry my new batts....how hot can they get and still be ok? I let them cool and they charged fine


how can I keep the temps down untill I get a MMM combo
