Hey guys, just joined the forum for some help! I'm currently redoing a bass tracker tx17. Everything has been going smooth and it is now completely gutted and the floors are being replace. The problem is, the previous owner left the wiring a mess! Two 12v batteries are used to power the trolling motor and a single cranking battery is used for the engine/bilge/aerator and now that i have it gutted, i want to change some wiring. First i want to add two lowrance hds units with direct power to a battery and add a stereo. What kind of batter/batteries do i need, and what should i run to them?? Thanks, Matt.
