JK..
How do you like your light bar? I'm looking for one for my son's 01 Cherokee.
What did ya pay if you don't mind me asking?
I see such a wide range of prices that not sure what to get.
Don't want it to poop out after a year?
Thanks and welcome

Why are you considering adding another battery?
Your alternators job is to carry all of the loads on your jeep while it is running. The battery gets the engine started and provides a boost when needed. ( too heavy a load for the alternator, alternator cant react fast enough, rpms too low to generate enough output, ect) So if your alternator is not keeping up now with the current loads you are placing on it adding a second battery will only buy you run time before the voltage starts to fall off. It will only be able to recharge both batteries if you give it ample time with spare amperage to do so.
so what is your alternators output?
how well is it keeping up or not?
