Thunder Tiger Raptors 30-90 - Imperio > RAPTOR 50 401-Hitec 6965-A123-Unregulated?

Anybody here running this combination unregulated on the tail? Will the 401 take 7.2v max on a full charge from an A123 setup? Voltage drops quickly to 6.8v and stays at 6.6v to 6.8v for 90% of the discharge. If a 401 will take the voltage, looks like it would be a good opportunity to get rid of a regulator and some connections.

you will most likely end up frying the 401. It may not last too long. Not to mention the tail servo....

401 is rated for 5 cell packs which peak over 7V off the charger. 401 has no problem with 7V and neither does the Hitec 6965 (and most all Hitec servos).

Sounds like this is a winner of a combo. Wish I had a charger that could handle A123's. Maybe my next round of hobby money.

Sorry for cross posting. Since I also have 2 Raptors that run A123's, I wanted to see if any Raptor owners were using A123's unregulated on the tail. You just don't see much discussion about this.

You can use any charger as long as you terminate the charge at 7.2v for a 2s. But you have to set and watch it. Or you can get a Dapter where you can even use an old nicad charger to charge your A123's. The Dapter will terminate the charge when it hits 7.2v. I think it will do up to 5s, but don't hold me to it. I bought one and never used it. Got a Mastech instead.
