Miss Jazzy Posted August 10, 2022 Report Share Posted August 10, 2022 Thinking about switching over to 36v T/M. I already have 4 batteries in my console with two for 24v T/M, one house, and one starting. If I go to 36v I would either have to stack one on top of another or put one on top of my access panel, witch I would have to beef up to support it. I know I’ve seen folks on here that have stacked them and would love to see some ideas. Quote Link to comment Share on other sites More sharing options...
Lap it Up Posted August 10, 2022 Report Share Posted August 10, 2022 You only need 4 batteries. 3 for troller, one for crank / house. Wire in a troller battery as backup crank and save weight and headaches. 1 2 Quote Link to comment Share on other sites More sharing options...
Miss Jazzy Posted August 10, 2022 Author Report Share Posted August 10, 2022 That would mean I would have to totally rewire everything plus neither of my current house/starting bats would be any good for a 36v setup. I fish offshore a good bit and love the redundancy of a dedicated “start” battery. Adding another battery would be far easier and I don’t mind the extra weight. 60-70 more lbs. isn’t going to make a difference. Thought about goin to lithium but then I would have to swap out an almost new three bank charger to boot. 1 Quote Link to comment Share on other sites More sharing options...

Sure you can stack them with a shelf, just better be a heckuva shelf! 1 Quote Link to comment Share on other sites More sharing options...

When I had my Pathy 22, I had a 36V old skool troller, and I fit 4 batteries in the console....make a battery box and you should be ok.....I think you are asking for trouble with a "shelf" and 150 lbs of batteries on top of each other..... dc Quote Link to comment Share on other sites More sharing options...
redzone1 Posted August 12, 2022 Report Share Posted August 12, 2022 I’m running a 4 battery set up as well with 3 deep cycles for the 112 I pilot and one 1,000 cranking amp cranking/house battery. I have my battery switch looped into one of my trolling motor batteries in case my cranking battery (#1) get low and won’t crank. I just flip the switch to both for extra juice. I’ve been using this set up for over a decade. Never an issue. Quote Link to comment Share on other sites More sharing options...
smilemaker Posted August 12, 2022 Report Share Posted August 12, 2022 I have an 04 2200TE with 5 group 31 batteries all under the console. My set up uses trollbridge 36 volt to charge on the run. The cranking battery is dedicated solely for cranking but I can connect all 5 in parallel if needed. Maybe a little overkill but in SC the tides can eat up a battery quickly. the new touchsceens also demand a lot of juice. Add a jl 800 amp and the power consumption almost needs a very long extension chord. Quote Link to comment Share on other sites More sharing options...

Two HDS gen3’s, vhf, 600 watt amp and radio. The last couple of trips I’ve ran my t/m completely down trying to hold over my spots. Even with setting up one of my t/m batteries to hopefully start my motor would not always be a guarantee. Plus I would only need to stack one battery over another. I have four on the floor now.

I’ve been using this set up for over a decade. Never an issue. I would love to do this. Currently 3 batts for the trolling motor and one as a crank/house. Im no electrician. How do I wire in one of my trolling motor batts to the open number two spot on my batter switch and not send the boats electrical system and engine 36V? Also after I do that if start the engine with that single trolling battery will the alternator charge just that single battery? Quote Link to comment Share on other sites More sharing options...

Please be very careful....you can "ARC' the batteries....if you correct them incorrectly, you could end up with 24V or 36V going to your engine and burn up a few things. If you are unsure, take it to a marine "Mechanic/electrician"....for the few $$$ it could save you. That said, I"ve learned electrical work from websites and watching a lot of YOUTUBE videos., but, I take my time, I prestage it outside the console, use a volt meter, etc. before I connect to the motor or TM. dc Quote Link to comment Share on other sites More sharing options...
Fastfish Posted September 9, 2022 Report Share Posted September 9, 2022 Fair enough but how is supposed to look. Quote Link to comment Share on other sites More sharing options...
Fastfish Posted September 9, 2022 Report Share Posted September 9, 2022 It appears one wire from the single pos post of the first batt in the series that is grounded should get it done Quote Link to comment Share on other sites More sharing options...
