1996 88hp johnson. Motor has 3-9 amp rectifier to charge battery. i guess it is UN regulated. Will this overcharge battery if I run long distances to fish, like running at high speed for up to an hour or two? Will it keep battery charged if I'am running livewell pump(going to put high speed pick up in so I can turn it off while running) stereo(will turn up while running, gotta hear something besides the motor) fish finder /gps combo, and possibly lights if early morning? Dont want to get where I'am going and need to fish (drift over near shore wrecks) with the motor running.
