running batteries in parallel

[Ryan_V]

I have been looking at a generator for the fish house(s). the one's I want are severely out of reach pricewise. My question is.....if I have a bunch of batteries, could I hook them in parallel in the back of my truck, get a large inverter and plug into the fish house??? I have the batteries, just need the inverter if this would work.

You can hook them up + to + and - to -. Not sure with the cord and inverter though. I've got 2 deep cycles in my house that are connected parallel. I run a 400W inverter for the TV & DVD Player. I picked up a Coleman 1800W generator at Home Depot for $329 for charging them.

Yes, that works.

Just keep in mind that one warm battery is probably as good as two cold ones. Cold really saps the capacity from batteries.

Yep, parallel will keep you running 12 volt and combine your available amp hours of all the batteries in use. You may lose a little bit of the amp hours jumping across the bridges hooking them in parallel but the loss will be pretty insignificant.

I have 9 batteries in my fishhouse and never charge except at home. I have a generator to run my coffee maker, so I could charge if it becomes necessary.

I am no expert on the subject but I was told that the batteries in parallel should be the same size and age. Ken

yep-the weaker battery will "pull down" the amps/volts from the stronger one
