When I began using the Li-manganese batts. 2 Jr servos
fried up. After a call to Duralite, they told me that these
batts. had to be used with a regulator. I bought it from them
and installed it.

I use LiMn for ECU's. This is the first time I hear about using them on Rx. They do not require a regulator for ECU's more than likely, but I would never trust any kind of Lithium anything without a regulator for Rx power.
Did the rep for Duralite misunderstood you?

Guys,
A 2s Li-Mn pack has a higher nominal and off the charger voltage than a 2s A123 pack. Li-Mn are the same as Lipos in terms of voltage. A 2s Li-Mn pack off the charger is 8.4 volts wheras a 2s A123 pack off the charger is 7.2 volts. That's why you need a regulator for the Li-Mn. Li-ions are ok but they can't deliver the current like A123's can and A123's can be charged at a much higher rate than Li-ions. I have been using A123's unregulated with no problems for a few years now.
