Battery Discharger - NiCads
« on: April 03, 2013, 02:42:11 AM »
Hi Guys
I had a chat with my local model shop dude about how to discharge the Nicad batteries. I generally used either a pair of Johnson 540 motors, or 380's, but a rather noisy exercise, and wasn't sure it was a good thing.
Anyway, he is/was big into RC Cars, and said they used a car headlight bulb to do the same thing, though much quieter.
So I built this. The wire over the bulb is stainless steel to prevent hands from touching the bulb, transfering oils & blowing the bulb. Same problem with the Maglite torch bulbs.

Great idea, only problem and someone with more knowledge will correct me
if I am wrong. I don't think it is good for nicads to go to full flat, doesn't
wreck them but shortens their life I think?
