So i was out on the lake yesterday for a few hours. Used the big motor a couple of times to make position changes. The last time I went to start the motor I get the grinding sound a couple of times before it would kick over. I have a brand new X2 power group 31 agm battery from batteries plus, only 5 months old. It stays on the charger all the time. I noticed on my helix unit the battery voltage was below 12, bouncing between 11.8/9.
I have 1 helix 12, 2 helix 10s, and 1 helix 9, an ethernet hub, a mega 360, and ultrex, power poles also.
I am wondering if I need a dedicated battery for all this stuff?
I was out only 5 hours yesterday and everything was fully charged before i went out.
Thoughts?
