onboard battery charger advice

[Kracker Jack]

I want to get some advice on which one to buy. What amp is best f or maintaining? I run a single battery know but will have duals very soon. It will also be permanently mounted in the boat with the plug out the side of the console for easy plug in. Thanks in advance.

Something like this would be fine.... https://www.batterystuff.com/battery...rgers/RS2.html

Its a 6amp per bank 2 bank charger. It will do the full 6 amp charge till full than a floating charge for maintenance.
