| I installed a new Solix 10 DI-SI GPS2 last fall. I connected it to the starting-cranking battery as recommended to avoid interference from connecting to the trolling motor batteries. I had issues with the battery getting drained when motor trolling all day. Before we go further, I know wiring pretty well, I used 10ga marine wire to wire the Solix, in-line fuse, everything soldered and heat shrink covered, etc. I knew the battery was older (Bought the boat Spring of 2019 from a widow, it had sat for a year...etc.). SO, this spring i bought a brand new Interstate marine cranking-starting battery. Yesterday, after about 4-5 hours of motor trolling for Walleyes, my voltage dropped from 12 down to 11.6 with a steady drop. Can those Solix SI-DI drain the battery faster than the motor can charge it? I called Humminbird, they said to buy a battery just for the Solix. So, my question is, should I just get a 12v tractor battery and wire in parallel with my staring battery to give the system longer life with the Solix connected, OR get a deep cycle just for the Solix?
If I get the 12v tractor battery and wire it in parallel with my starter battery to help with longer life with the solix attached, can my Minn kota on board charger deal with that? It's one of those newer "digital" ones with some brains in it. I have my starting battery on one of the charging circuits.
