Deluxe Charge Rate Limiter for Small Capacity NiCad Batteries.
Here is a deluxe version of the simple charge rate limiter, using the same
idea but with the ability to charge two packs simultaneously from a single
wall charger. For circuit description and parts list, see the simple charger
page. Since wall chargers provide about 55 mA, you should not use this
dual circuit to charge batteries at rates greater than 27 mA (for a total
of 54 mA).
