SkyRC BD200 Battery Discharger & Analyzer

SKU: 340-10-136

Availability: Out of stock




The BD200 is a powerful discharging device that allows the user to discharge a battery at up to 30 amps or 200 watts and also measures and compares the performance of batteries. BD200 allows for the precise measurement of battery capacity and takes the guesswork out of choosing the best battery for your application.


The BD200 is much more than a simple battery discharger or a battery load tester. It will test virtually any type or size of battery, any chemistry or number of cells, up to 35 volts.


It is small with a high performance cooling system and uses MOS fets from the well-known brand IXYS, to make sure it can discharge at 200 watts continuously.


PC software supplied with the BD200 is easy to use, intuitive. There are two discharge mode: 1. Constant Power; 2. Constant Current. The software can automatic sensing of battery cell count and recommends a minimum safe discharge voltage. Discharge tests may be viewed in Amp Hours, Watt Hours or Minutes. Results can be graphed as Voltage vs. Amp hours, Watt hours, Minutes.

Couldn't pass up the July 4th deal!Review by Joe
Five stars all the way! R/C Juice ROCKS with shipping speed! I got this discharger 2 days faster than items I ordered 3 days before them! The discharger works great so far but the software takes a little time to learn. I'll figure it out though. R/C Juice shows that it is amazing for price and speed of shipping.! I'll likely be back for more... (Posted on 7/10/2020)
Great tool for those who charge multiple batteriesReview by Ben
As a practical matter this is a must have for those who might charge multiple batteries. Most chargers have weak discharge capabilities which means it can take multiple hours / days to get everything discharged and stored again if you don't run everything down. With this, I can discharge a battery in about 15-30 minutes safely rather than the 4 plus hours my charger might take. Additionally, it has a PC link which you can use to monitor battery capacity and overall battery health. SkyRC PC software can be quirky, but this one worked just fine. (Posted on 1/25/2020)
Sky RC BD200Review by STLNLST
Excellent little device for discharging at high amps. Most of us Icharger guys like to dump and 40amps but this requires turning a dual charger into a single charger. Not anymore with the BD200. While it only discharges up to 30amps it gets the job done and frees up a second charging bank. Price is awesome especially if you catch it on sale. RcJuice is your go to place for the budget racer and serious racer. (Posted on 8/13/2019)
The BD200 Helps Lengthen Your Battery LifeReview by Plane Fun
I bought this unit when it was on sale for $69.99 and put it through its paces. It is a good value at the regular price, but at that sale price, it is especially money well spent !
Here is a link to the video desktop review of it:

If you use this to discharge your batteries to the suggested storage volts, it will help you get the maximum life from them. (Posted on 8/2/2019)

can this be used on one cell batteries
No, it will not work with 1s batteries. 2s and higher up to 35v.
