Thanks for the information. I was unaware of the restrictions on the AAA NiMH Batteries in Europe; also that the charging curve was different.
I know that you have mentioned before that shipping said battery packs has been a problem, due to postal restrictions.
Also good to know that the OMP sleds are less expensive than MP2x00s.
These are all good things to file away for future reference.

Prior to them, I gave up on NiCd’s, ordered a very handy, little Velleman kit voltage converter, attached the biggest heat sink the hobby shop had, and hooked it to a sealed Pb-acid battery. Yeah, the rig was kinda heavy and somewhat bulky, but I was able to ignore recharging: rarely ran out of juice even if unplugged all day long. Plus I didn’t get radiated by 60 cycle.
