9xr 12Volt input - What is it supposed to do?

Postby butchalline » 31 Aug 2013, 23:07

I have a 9xr with the HK recommended LiPo. For safety reasons, I always charge the battery out of the 9xr with a balance charger.

Just for kicks, I hooked up a variable voltage lab supply to the 12 V connector observing proper polarity.

Absolutely NOTHING happened. No current drawn, no change in voltage on LCD. Tried with Tx both on and off.

I assumed that the 12V jack was for charging, but it does not seem to do so.

So... what is the 12V jack supposed to do?

Charge the battery. You need more than the voltage you were supplying to do that.
