The heading says PT185 but then you say Nitro 185???? I have a Pro Team 185 and just had to move my charger since I upgraded to a 24v Troller. I used to have my charger mounted in between starter and troller battery but I had to move it to add the extra battery for the 24v setup. I decided to mount the charger in the small compartment behind the passenger seat. I just got a big ol' drill bit and drilled a hole from the small compartment to the compartment where the batteries are. I ran the wires from the charger to the batteries through the hole and now I can just pop open that little compartment and plug her in.
