[NSRCA-discussion] AAA NimH batterys

[DaveL322 at comcast.net]

I've been using pairs of the 6v720s (through 2 parallel switches) for 4 years in the EMCs and Vivats - probably 3,000 flights total.  Voltage drop is not an issue with the 2 packs in parallel - I didn't even bother to regulators.  I did not find them to be as durable (compared to Nicd) with respect to number of cycles.

Regards,

Dave
