Hobbyzone Super Cub 120V charger
Remove this ad - become a site supporter!
I bought a SC off someone who said that they never did fly it. The plane certainly does not look like it has been flown. When I tried to charge the battery the light on the 120 V charge flashed like it is supposed to but the transformer got quite warm but the battery didn't. After a couple hours the battery didn't seem to charge so I put it on the 12 V charger and it charged fine. I measured the voltage off the 120V charger and it is 16.7 V, the 12 V charger is 12V.
Any thoughts as to why the 120V charger isn't charging the battery? Did I just not leave it long enough? I would think that after a couple hours the battery would be warm but the transformer shouldn't increase much in temp.
If the charge is toast, is there any difference in charging with the 120 vs the 12 v? I have a battery for the trailer in the garage that I can use to charge the plane battery so if there is no difference I really don't need to go out and spend another $20 on a 120V charger.

Re: Hobbyzone Super Cub 120V charger
You're safe to charge on the 12V charger providing you keep the amps low. You shouldn't charge those packs at more than 1 or 1.5A, as they don't like being overly hot too much.
If you're getting a voltage reading off the 120V charger, I'm sure it's working. However, it charges pretty slow if I remember correctly. If you've got a 12V charger, I'd just use that.
