drewfl Posted August 9, 2017 Report Share Posted August 9, 2017 I am having issues with my power. All compoments are running off my crank battery. Has anyone added an extra battery to a 2000 21' MA? If so, any thoughts to the addition of a battery under the helm seat, space is very limited. Any help would be appreciated? Link to comment Share on other sites More sharing options...
captpn Posted August 9, 2017 Report Share Posted August 9, 2017 I have an extra battery in the console via Perko switch. Works fine. Should work the same under the helm seat. Link to comment Share on other sites More sharing options...
drewfl Posted August 10, 2017 Author Report Share Posted August 10, 2017 Thank you captpn for the quick response! Running into low battery and not cranking at end of day of fishing; they can't find any issues w/ stator or other problems.. Shop says components must be just draining the battery. The thing that has me scratching my head is that this is a new issue, with new batteries. Link to comment Share on other sites More sharing options...
captbryan Posted September 5, 2017 Report Share Posted September 5, 2017 If you have trolling motor batteries you can use one of those for your extra battery. That's what myself and a lot of other people on here have done Diagram is in saved post section. Link to comment Share on other sites More sharing options...

My trolling motors are on a totally separate circuit and it was too difficult to try and connect. It worked out great. Again.. thanks. Link to comment Share on other sites More sharing options...
JT Quinta Posted March 21, 2019 Report Share Posted March 21, 2019 I have three batteries under the front seat for the 36V trolling motor. If you wire the 3rd trolling battery with a separate battery disconnect switch between the High 2 and the Low 3 battery and run that to the main battery switch 2 you now have the ability to run two batteries in parallel and or use the #3 as a backup starter battery. What you CANNOT do is run "battery 2" or "both" on the main motor switch while energizing the trolling circuit. Link to comment Share on other sites More sharing options...

JT Quinta Posted March 22, 2019 Report Share Posted March 22, 2019 Call him up..., really nice guy to talk to. I think they’re around $300/$400 depending on size. Link to comment Share on other sites More sharing options...
triplec Posted March 22, 2019 Report Share Posted March 22, 2019 Got this posted in the product info section so you replies may be limited and it looks like you have solved the issue but its absolutely worth the effort to tie some of those batts together or a charge on run like http://www.stealth1charging.com I run the stealth system and tie via switch for emergency. I am surprised the batts are in the console. I have the 18.5 MA but have 3 groups 31's in the console. I set up using the ole Hobo plan. Link to comment Share on other sites More sharing options...
