For Charging both battries at once or switching ?

What are you planning to run..?

[markyboy]

want to charge both at same time, am planning to use the 2nd battery for another amp i have but its a big one so its drawing to much for one battery as i have another 2 amps running of the standard battery. i have the relay and power leads , just need to know where to put them.

[kam-325i]

Might need to get a bigger alternator. Do you want the charging to be automatic.

Might be easier to get a bigger battery........i got a huge one for a diesel engine, one benifit is that its spins the starter a lot quicker in the mornings !!!

[markyboy]

yer could do ,

[markyboy]

but will that give enough power 2 run 2 amps without dimming the lights and crap

[kam-325i]

Depends on how big the amps are.........

What engine have you got.......

Normally, the best option is to get a bigger alternator and bigger battery....

[zaust]

I use the standered alt and a normal battery, have two massive amp's and never have a problem unless i leave it runing for an hour with the engine off..

How ever if you reall still want another battery, You can go to a caravan place and buy a a charging relay.

Consist of earth wire, Constant live, Switch Live 1 fuse and a live to your extra battery ,Which will need it's own earth. should be more than you need fella.

I am guessing you are running a power cap?
