So I'm looking to get a dedicated 12-volt lithium in the 50 AH range to run 2 units on the bow. I don't fish big tournaments so I'm looking to save some money by getting one of the generic lithiums listed on Amazon. Anyone had success with one of the cheaper brands? I already bought a brand name 33 AH battery and wasn't all that impressed with it so it is going to use that to run my unit at the helm. Thanks for any advice.
