Your pump and Fishfinder will have a usage rating in ma (milliamps) which are 1000th of an amp. My FF is 475ma, which means I can run it for 2+ hours on 1 amp (draw will vary if you are using the backlight). So a 12v 7ah (a more common and less expensive battery configuration) will run my FF 14+ hours.

If you are using a 500gph bait pump you either need to use a 6v battery, use a control to limit the voltage to the pump, or restrict the water flow into the tank. Too much water flow into the tank can kill the bait just like too little.

I think the HR is supposed to be ah like on the 3.3ah battery. Sometimes the translation from Chinese to English can suffer.
