Hi All

I m at the stage where I have charged quite a few 18650 cells now and am wanting to know what discharges people are using to test their cells, I am now charging 36cells at a time and am wanting to discharge about the same amount, does any one have any advice on which ones to get

I use these. They will do 4 cells at once individually and completely automates the process. You just put a cell in. It will charge to 4.22v, then automatically start discharging, stop a 2.8v, then automatically charge back up to 4.22v. The capacity during discharge is shown on the screen. I have 5 of them running at once (20 cells).

I use one of these http://s.click.aliexpress.com/e/B6aeIyz

If you have a lot of cells I'd recommend two or more of these.

I also have four iMax B6's (which I got before discovering the BT C3100) - the iMax's are a bit more cumbersome and possibly less accurate.

Cheers, Paul

I purchased 4 liito kala 500 for my discharging after having such a slow going with my 4 imax b6 mini's. I used the reviews in this site to make my decision. Its up to you where to purchase from.

I use the BT-C3100 and it works great. It's decently fast and quite accurate.

When I'm doing big batches on built up batteries, I use a halogen bulb discharger I built along with a wattsup meter.

What rate do you cycle your batteries at on your BT-3100s? I do mine at 700ma. I've tried 1amp but they seem to get too hot sometimes.

Do mine at 1000mah just to speed things up. I should go back and do it at 100mah as that's the draw on my cells. Could be an interesting test. Heat is fine HOT is bad..
