PT Buds,

Just got my 2010 GMC Sierra SLE Z71 i noticed i have space to add another battery therefore, i want to purchase an additional battery but i know i have to add an isolator and some kinda solenoid but want to make sure i purchase the right one and which is best recommended. Thanks for input!!!

Stinger SGP32 200 amp Battery Isolator and Relay.


This will work also

 

Thanks i like that it comes with a switch and led lights letting you know what battery its charging!

 

Thanks! Wondering if i can add a set of lights so i can tell what battery is charging

 

I would have it so when the ignition is on both batteries are being used and charged then when you turn off the key it will disconnect the second battery.
