Does anyone know the non-destructive current sourcing capabilities of
Nicads? or gel cells for that matter. While batteries have a nominal
amp-hour rating, this value does not indicate the maximum rate that the
battery can be discharged. Also the RC hobby catalogs describe "SCR"
Nicads which are optimized for rapid charge/discharge. Some 1 A-H SCR
Nicads are described as bing able to provide 20+ amps for short periods!

In particular, I need to provide 3-4 Amps for periods of 15-20 minutes
before recharging. What is the smallest rechargeable Nicad that I could
use?
