my cart has an empty spot for a battery under drivers seat...was wanting to add lights and a radio and two speakers....will it be ok to put a deep cycle marine (boat)battery in there and run off that??i know i will have to charge that batt.seperate but no big deal to me.just want to see if anyone else has done this and if it will work like im thinking.

I have a marine deep cycle size 24m in that spot.It powers my stereo and my leds. I use a hold down with 2 j-bolts that I got from an auto part store,it doesn't move at all.

Having an accessory battery will increase the life of the 36v system just because there will be no imbalance created by an imbalanced drain on 2 of the 6 batteries.

Proper use and charging of the accessory battery will determine how long it stays healthy. If you choose a cranking battery, deep discharges will hurt it. A deep cycle would be better but, any wet cell battery prefers to be recharged soon after use. Never leave them to just sit in a state of discharge.

Make sure when you add this battery, that all your wires, raido / lights, pos + / neg _, go to the battery post, NO grounds to the frame

Good Point! Everything on an EV is a 2 wire system.

I just did this today for my stereo and lights, works great.

What about something like this to power the accessories. I dont have room for a full size battery, but PowerWheels batteries are 12v and it looks like they will fit in the fenderwell.

Get the biggest deep cell battery you can.I mounted mine in a plastic marine battery box works great.I run my winch,parking lights,head lights,driving lights,tail lights,brake lights,radio and i dont have to charge it very often.I also added a fuse block so everything has a fuse protection
