SKYRCBD250 250 Watt 35 Amp Variable Battery Discharger and Analyzer Tester for Hobby Remote Control Vehicles Digital LED Display Continuous Discharge

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 ‼️ ⭐⭐⭐⭐⭐

Works well as a discharger, but be aware that if this product is being used connected to a pc (using the dedicated app), it can destroy the pc and the charger if the wrong combination of keys is pressed.This sounds ridiculous, but I was using this discharger connected to a laptop via a usb port (because the app provides more options than using it stand-alone).My cat jumped onto the table and walked straight onto the keyboard before I could stop him.I have no idea what keys he was standing on, but the discharger immediately began fizzing and smoking and the laptop shutdown and won't boot.I suspect the battery I was discharging (5S LIPO) was connected directly to the usb port.So, the discharger is a write-off and, probably, so is the laptop.My error for not keeping the cat away from what I was doing, but I wouldn't have expected any combination of keys to have the effect it had (maybe abort the discharge, or lock up the laptop, but not complete thermal destruction).So......... if you have this discharger and you use it connected to a pc, be careful.

Worrh every penny quality easy to use I recommend 👌

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.

Quick way to discharge your batteries without running through your charger
