I've been running my L.A , Ohio and Xia on two 6v 1.2 amp Sealed lead acid batteries for a while now. (In series , I run the Rec and servo's and motor off one and use both to power the 12v pump.) As soon as ive run the boat i put them back on charge. I have found that even charging them overnight I only get about 30 to 40 minutes run time. before the servo's start going sluggish. I'm using the standard car 12v charger.
Am i missing something? Is this right or should I be getting much more run time out of them? please comment.
