Harry, further reply. I've been trying out the Li-ion chargers on the Radical's NiMh battery, and both Li-ion chargers cut out at just over 42 volts, sensed by the voltage it seems. That's too low for the 33 cell Radical battery, but actually a good enough full charge level for the standard 30 cell NiMh battery, being just over 1.4 volts per cell.
If that also holds good for a standard eZee NiMh battery, and I think it will, they will be ok. I can't guarantee it of course, but perhaps another member who has both charger types and an NiMh battery would check by using the Li-ion on it and checking the battery voltage at end of charge. When Ian returns from holiday he might do that for you since he has the chargers and a standard NiMh battery.
