Hi all,
my truck is at Selective Sound for the custom sub install, has been for 2 months now. dont ask. lets just say Davis better do me proud or ill kill him.
this week end i went up and installed my new DC Power 270XP alt and a odyssey batt. i want to add a second batt and am thinking a pc-2150 from odyssey. my primary is pc-1500 which is the biggest i can fit in the stock location. the truck has a secondary space for a second batt that i plan on squeezing the 2150 in on its side.
will having two batts of different sizes (capacities) be bad to connect together?
should i install a batt isolator between the two?
or would i be better off just running a second batt that matches the primary?
im not in the habit of listening to music with the truck off and if i do its never more than 15-20mins. usually while the girlfriend is in a store (she knows i dont like to wait).

you will be fine.

you can use an isolator if you like.

thnx for the fast response Father.
so there will be no concern of one batt draining the other?
know of any place i can find a 300amp isolator?

Dont bother with an isolator, just run the batteries together and you will be fine.

Mr.DatSubishi

We always run multiples of the exact same battery to prevent any under/overcharging issues. We do Odysseys as well and I wouldn't do anything that could even remotely shorten the life of these pricey, quality batteries. There was recently another thread almost identical to this. There may be some more opinions in there.
