You need to test the battery voltage wen the pump is running, you will see that the voltage drops even lower. Most controllers have a low voltage cut off. Are you running one pump or two? Two pumps and you really need a decent battery. There are smart chargers and really smart chargers as well, ctek are pretty good.
