SkyRC BD250 250W 35A LiPo/LiHV/NiMH Battery Discharger & Analyzer

Does exactly what you need it to do. Discharges your batteries in minutes.. Works great..

Uses a EC3 or ic3 adapter for all your batteries. I discharge 3s 4s and 6s batteries. Your input values will vary but here are mine: 3S 11.1, 6A, 4S 14.5 12A, 6S 22 15AWhen they indicator light says done let the fan continue cooling and the light stay on until these go off to properly cool the unit. Adjust your discharge values to your own personal use this is a very user friendly discharge device that works extremely well.Highly recommend ‼️ ⭐⭐⭐⭐⭐

What can I say, it gets the job done!

I love this battery capacity tester!Many great features:250 W max draw lets you test even big batteries quickly. It looks cool while running (blue LEDs on the fans). It only launches its fan if it gets too hot. When running it quickly alternates between AH and battery volts and amps. It lets you customize the low voltage cutoff, and the max amps to draw. The knob turning is "smart", intuitively detecting when you want to make big or small changes to the value. The interface is simple, therefore easy to remember over time (for those of us sometimes experiencing senior moments!). You can provide external power through micro-USB so its own power draw does not pollute the results, and so that it remains "on" even if the BMS in the battery you are testing cuts off.But beware: it will silently rollover back to 0 AH when it crosses ~65 AH, which makes testing batteries larger than 65 AH confusing until you realize this. If you test a battery overnight, wake up, and see 20 AH, you cannot know if it was really 20 AH or maybe 85 AH.The previous model (SKYRC BD200) had the same silent ~65 AH limit, so I purchased this one hoping that was fixed, but alas, no.

This discharger has a ton of features! It does a great job getting your battery down to storage voltage quickly and safely. I do wish it gave you each cell individually but you can attach a balance reader for that anyways. You will love it for discharging your lipo batteries!

The device doesn't instantiate under Win10 or Win11 - most likely due to the fact that the USB VID is 0x0000 and the USB PID is 0x0001.Ubuntu 22 will report this problem as well but seems to continue to try and talk to the device eventually instantiating it as a USB HID device. Unfortunately, the software only runs on Windows.Customer service is non-existent - SkyRC has a chat feature with the boast "We respond immediately" - I waited about 6 hours with no response at all.The device can have it's firmware updated, but only if you can get connected to it in the first place.Too bad - seems like an interesting device but the real value comes from the software as the interface on the device itself is very painful to use.Like lots of things now; the hardware seems OK but the software is awful.Tried 2 devices so it wasn't a defective device - these just won't instantiate and connect on Windows. I suspect the firmware was changed at some point because I know people that have been able to use them on Win10 and Win11 but clearly not anymore.

Worrh every penny quality easy to use I recommend 👌

I've been using this discharger for months. My son races 17.5 buggy and 13.5 wheeler. We use this to wake up our batteries for racing to get them warmed up and the internal resistance lower on our race packs combined with pretty high charge rates. It serves us well and I'm pretty happy with the purchase and I haven't had any problems with it whatsoever. It's pretty awesome.
