| I have read several post online that say they run there starting battery as part of a 36 volt system. My question is is this possible and will it hurt anyting, I'm asking because I have a 36 volt terrova(got a screaming deal on it) and a 16.5 boat and not putting in a 4th battery in would save weight and room. And will a deep cycle battery work for starting battery or should I stay with a starting battery? I also have a minn Kota 3 bank charger I plug in after every day of fishing.

| It is possible to use one of your TM batteries, but it is begging for trouble.
You could save weight and space by using group 24 batteries for the TM.
Or you could sell the 36 volt and buy a 24 volt. |

Location: Lake Elmo, MN | Highly advise you NOT to go this route. Your starting battery is all that is between you and a long trolling motor trip (assuming that battery is OK) back to your lodge or trailer. And we all know....the time it decides to fail will be right a s a huge storm, or nightfall is approaching and you need to get out of there FAST.
If on a large body of water, a dead starting battery is about as bad as it gets. Sure you can make some switches (change a trolling over to get some power) but it's a huge hassle and not worth the bucks you save.
When it comes to your main motor....take care of it, and it will take care of you. That includes power.

| It can be done successfully. There were problems running an optimax and 4 10" screen depthfinders due to the amount of amps needed to run the opti. I read it on bass boat central, you can search the topic there, they show a wiring schematic and explain it. If I remember correctly they recommended group 31s for all three and there would be no issues. |

Location: Sun Prairie, WI | PSAGuy I read something awhile ago and I now do it. I carry a set of jumper cables in the boat with me so in the event that my starting battery dies I can jump it with one of my trolling batteries to fire the engine. I have had to do this once when the starting battery gave up the ghost. Just a good tip I thought I could share here. |

Location: Hayward, WI | For several years I ran 2 batteries in my Alumacraft Navigator 165. Ran a 70lb 24 volt Minn Kota, 2 Lowrance 520C's, and only had to start a 50 4 stroke Merc. Never had a problem with running that setup. Maybe it isn't tecnically "correct" but I charge batteries with an onboard charger after every outing and never ran into issues with dead batteries or short battery life. Normally get 4 or more years on a set of batteries.
I hook the trolling motor up to both batteries to make 24 volts, then hook all accessories to the battery the outboard is hooked up to so it charged a little on longer runs.
Always worked for me, though I will have a designated starting battery in my new boat. Partly just due to boat layout and battery placement in the boat. |

Location: Lake Elmo, MN | JJMusky.....Excellent idea. I was one of those guys stuck with a bad starting battery many years ago. Was out in Cormorant Bay on Rainy Lake (miles from ANYTHING). I swore I'd never skimp on anything for the boat ever again. Cables are a great backup idea.
Heading out today as a matter of fact to buy a new Oddysey Battery for my Ranger. New season.....new power. |

Location: Money, PA | I would keep them separate for sure! You can also carry a portable battery booster with you in case of power loss....Did this with my Erie boat for years.

| I had 4 batteries last year and will probably do the same again this year. Just read posts over the winter where people were doing it .

Location: Mauston, Wisconsin | Really bad idea! Others have already said why, I too keep a set of jumper cables in the boat, seems like starting battery problems always happens when you are far from camp or human habitation and no other boats are around. Once 10 miles from camp on a remote Canadian lake....
If you discharge your starting battery with the TM, you are going to be SOL! Actually, its a stupid idea! If you do this, and fish remote area's up in Canada you better have the essentials to camp out for the duration,,,,
Have fun!

| Sell the 101 (it's overkill for your rig), use the profits to get an 80 and new batteries. |

| Yup, bad idea. 36V 101 is overkill. Get a 24V 80, and use 2 TM batteries, and a Dual Purpose battery(depending on MCA requirements for your motor) for your cranking/accessory battery. Charge after every outing.
As for carrying jumper cables? Excellent idea. I had my starting battery crap out during a tournament, running sonars and the livewell all day. PITA to swap a TM battery to start the motor. After that, I used a 12V TM plug, and attached it to a set of cheap jumper cables. The little zippered pouch they came in fit in my glove box in the passenger console. If needed, just plug it in to the rear TM recept. Make sure you unplug the 24 or 36V TM from the front.

Location: Uxbridge Ontario | You can surge your trolling motor if you have a 36v system tied to your cranking battery. My terrova explicitly said to not run a cranking battery to the 36v system.
