Batteries...

So I decided to change my starting battery and solar batteries up to Optima batteries. Question though, I opted to also run the Pelfrey battery cage for a group31 battery. I went with the dual purpose 31M. Any issues running that in the truck? Since its a dual purpose its both starting and deep cycle. Any downside to have 900CA?


Also swapping out the non-sealed LA batteries for these two Optima 34m's. Im cutting my ah WAY down with these but seeing as how theyre in the back of a truck i'd rather run these two 55ah batteries in series to wind up with 110ah than the 220ah lead acid batteries. Plus I have nearly 50lbs in the bed.

 

You upgrading alternator?
Why Optima?

 

I had not planned on upgrading alternator, I don't have alot of draw on the trucks system, as long as nothing on the switchpro is on and im not using the winch.

Why optima, I have an existing relationship with them and have always been happy with their products.

 

Do you have to change to a longer cable to use the 31M ?

 

I’m going to rewire all of that to aluminum distribution posts.

 

Oh the two 34m’s are isolated and only charged via solar. The alternator is only charging the 31

 

Gotcha. Was gonna say stock alt charging up 3 batteries might not cut it:/
