    My negative experience with my solar charger Epever Tracer10415AN and a warning for using it with Lithium Battery

    I Did the same thing once . I thought i fried the controller. Took all wires off and shorted the terminals on the controller to discharge any internal charge. left it that way for 20 minutes. Connected battery's and it came to life.Connected the battery's and has been fine ever since.

    Anyone have experience with Volvo Penta BMS?

    What i would do is contact volvo directly and talk to a teck and not a sales person. I worked with mercruser and they would always help out a buyer.With computer controlled engines fooling with charging systems can end up with some real nasty results.

    Battery gravity doesn’t look good

    You can get a tester any place they sell auto parts. Harbor freight sells a good one dirt cheep or let the place you got it from check it. Where i worked we sold a lot of batteries and every once in a while you get a bad one.

    Battery gravity doesn’t look good

    The first thing i would do is disconnect all the battery's And put a load test to them separately. You may have full voltage but no or low amps. If that is the case your battery has a bad cell.
