The test is the cars and charger.
I run 2w and 4w offroad, TC occasionally.
I was running 2w and the car stopped, no power. I pulled the body, wiggled wires and it turned on again, steering servo powered up etc.
Started to run it again thinking a connector came loose. It happened again.
It is at the positive port on the battery that is intermittant.
I changed the leads to the ports and no difference, still intermittant so I stopped using that battery.
Went to the other battery with no problems, same leads same cars.
Now I'm having the same problems with the second battery after using it for 2race nights, about 10 charge cycles. 2 practice runs and 3 heats (2 qualifiers and mains) each nite.
The Avionics charger shows "No battery detected" when trying to charge it.
I'm thinking the batterys aren't taking the jolts from offroading at So Cal.
Big jumps, doubles and triples. Make some and miss some.
Whatta you think?
