Sky discharger

Works well except that to get to my preferred storage voltage of 3.83 I have to set the discharger to 3.76 per cell.

William M.
Excellent product

Great price point, accessories reasonable too. Most important Buddy RC customer service and product knowledge is exceptional.

Charlie C.
Works perfectly. You need this discharger.

The discharger works as advertized. Settings needed are intuitive and easy to understand and set up for the battery being discharged. This unit is a sound investment for those wanting to keep their batteries in top shape and not be tempted to store them at above storage charge. I believe the unit will pay for itself in the long run by allowing batteries, especially lipos, to last longer and not have to be prematurely replaced because of improper storage voltages.

Adam G.
Poor instructions and performance

Got the unit yesterday. The unit does not work per the instructions, but I finally figured out how to get it to work. It did discharge my 6 cell Lipos quickly, but I can not get it to discharge my 2-cell Lipo receiver packs. I'm sure disappointed in this discharger.

SkyRC 250 - worked great!

I received the SkyRC250 battery discharger two days after I ordered it! I immediately used it on my 6S LiPos and it worked flawlessly. I used a discharge rate of 10.5A and it was discharged in minutes. Next, I checked the cells and each were in the 3.71-3.73V range per cell. I highly recommend this unit! Excellent performance and super-fast shipping by the Buddy RC team. Thank you!
