Was riding this past weekend and a group of us were talking about who had done what to their rigs. I asked the million dollar question, at what point is there to many accessories on one battery? I understand the alternator needs to keep up with the demand and charge the battery. For instance on my rig, I have two LED whip lights, 42" LED light bar, 3500 lb wench, and a MTX overhead audio unit that has a 280 watt amp in it. I want to add a sub, do I need a second battery? Is the stock battery just fine? Do I upgrade the stock battery? I was surprised that I wasn't the only one out riding who was clueless on the topic, and even more shocked that people run more accessories on a single stock battery. I have everything set up on my rig (2020 X3 Mac Turbo) to turn off once you turn the unit off so there isn't anything draining the battery. Any help would be greatly appreciated.
