Third Battery - VHF/UHF Radio Install

[springrnco]

I apologize for not being more clear. The radio is an Tx/Rx radio and although I agree that I should be able to Rx forever I am very concerned about Tx'ing at 50watts.
Thanks.

I guess if you want to run it off a third battery, it doesn't sound like a bad idea. I would probably mount two in the bed, then put in an isolator switch so you do not drain your main batteries while using it. Once, restarted you can flip the isolator switch and re-charge them.
