Hi all. I have a bearprint (re-branded freego?, 36v, 10ah battery) that's about 6 years old now. Lately it just stops working for no apparent reason. Have disconnected brake cut-off wires to simplify finding the problem to no avail. Battery at base still shows 41v even when not working, meter shows ful strentgh. Turning everything off and on makes no difference.Check continuity of all connections wih a multimeter, no problem. Strange thing is, every time this happens, after 1 or 2 days, it comes back to life. Any input would be much appreciated.
