I would like to buy a new battery for my R-85 turbo , with TEC3 ecu , DFU .... 2 fuel pumps.....etc

If i use a battery with these details :

internal resistance : 4.2mohm
5 sec cranking : 925 A
short circuit current : 2400 A

constant current disharge in amp to 10 volts
cca rating : 380
ah rating : 30 Ah

These are the details of the Stinger sp800 with 25 lbr weight !

Is good enough or its neccesary something more powerful ?
