MS Paint FTW!

make sure and used a sealed battery for the internal battery..

and it is also recommended to stick to the same brand / type of battery when using more than one.. if not, a battery isolator is recommended..

But riadb, you missing a fuse near the second battery that connects to the front. And the lil +ve part going back to the engine is the wiring harness right? I hope the guy don't interpret that going to ground off on the engine as well. Divali done we doh wah no fireworks

if i use 0\3 gauge wire for chargin purposes ONLY, wudnt dat charge the batterys faster.?..cuz i no dat the thicker wire, more dan likely u wudnt sacrifice voltage

^^ Yeh but at some point you will reach a limit... with a stock alt it probably doesn't make sense using more than 4 or 2 AWG.

but if u hav an aftermarket alt, eg : stinger 300A alt, wud u STILL USE 4AWG or 0AWg in dis case for chargin d batterys?

I thought it was implied, but yes a larger gauge cable may be necessary.

It is now implied

cud u use ground terminals for groundin off d amps and batterys, instead of usin d chasis?. jus askin

[theblitz]

What do you mean? If you mean a gounding block then of course that has to be connected to some valid grounding point.

instead of taking the power from battery number 2 can i used battery number1....????

[theblitz]

^^^ Because both batteries are in parallel it doesn't matter which one you tap off. Its assumed that the 2nd battery is closer to your equipment that's why the diagram shows that connection. Personally I would go for the shorter run of wire.

[certified_dealer]

well in that case the front battery is closer..thanks..
