Hi All,

Having a few teething problems.

We have fitted 2 x Li-ion 24V batteries in serial (reading upwards of 50V)
1 x Infineon 35A controller
1 x Ultra Motor 500W motor
1 x Cycle Analyst

Fitted to a Schwinn Stingray.

Works fine up to 25mph from stationary. But if you accelerate to any speed release the throttle and re-apply it cuts out and you have to reset the system. Once reset if will pull away at full throttle no problem again?

Any ideas.....?

Many thanks
