My 2010 E550 is a 4matic. As such, the battery is under the hood. I was curious if I could add a second full sized battery in the trunk where the rwd models have one. My thoughts behind this is I live in a cold climate, do make a number of short trips, have a hardwired radar detector, aftermarket sub and amp, and now plan to hardwire a dual dash cam. I can buy one of the cell link b or blackvue batteries, but for roughly the same cost, I could add a full second agm. I know running the wiring will be somewhat time consuming but I am able to do so myself. The camera will run when triggered as I'm sick of door dings and scrapes and the associated costs of fixing them.
I'm curious if there is a downside to going this route. Will charging be compromised/excessive strain put on the alternator? Would I be less likely to recharge when driving?
What are your thoughts on upside vs downsides?
Thank you!
