'cantruchd' That's yet another way to do it, and also a good way if the connections doesn't come loose, because then weird battery levels will be reported (voltage) if the battery goes from single to dual now and then, but really smart way to do this , simple yet effective, and still having the option of 2x single battery's if ever needed, i will try to do the same with a future scud mod, and make additional tutorial in post #2

'Pillum' what do you mean????
