    Discharging 400AH cells

    It says it is for 6/12 v. How will it drain a 3.4v battery? Will it take forever? I have the smaller/plain load tester that you hold the switch on and it heats the element inside, is this the same as the Carbon Pile Load Tester?

    Jerky Starts

    Aloha, When starting out, the motor hesitates and goes into reverse for a split second and then forward causing a clunk. (If I slightly roll forward it is fine. I checked all my wiring and also did a "re-learn" but still happens. Probably totally unrelated, the motor is totally silent...
