Been thinking of doing a dual battery system but it seems all i really need is a deep cycle AGM since it will primarily be providing power for my 20W / 1.45A BaJa LED's for setting up camp and maybe some amplified music from my 600 watt amp (low volume/not at same time) for a few hours.
Figured i would put down where i am so far and revisit when i am ready (also get some input). So far:
AGM Group 34 in ether an X2Power
X2Power Premium AGM BCI Group 34 Car and Truck Battery - SLI34AGMDP at Batteries Plus Bulbs
Or Odyssey battery (not sure model Odyssey).
And to provide enough voltage to charge the AGM i will need a Voltage Booster like this:
HKB Electronics
Or i could go with a battery tender
Amazon.com: NOCO GENIUS5, 5-Amp Fully-Automatic Smart Charger, 6V and 12V Battery Charger, Battery Maintainer, Trickle Charger, and Battery Desulfator with Temperature Compensation: Automotive
I really prefer to do things the safest and best way so not to mess with my 4R since it seems its sensitive to changes in electrical modifications (have had issues with a remote start). So i may just upgrade the battery and forgo the Voltage Booster, but it sounds like a battery tender may not be enough if i don't drive much daily.
I would just go with a regular high CCA lead acid battery so not to mess with things but i would really like to be able to have some backup power for those 2 things.
So far that's all the info i have gathered.
