I found a 110 mah nimh in my $5 thundercharger! Sure, it's nowhere near your (microspeed's) 200 mah, but it's way better than the standard Tomy and MS 50 mah. I was so surprised when I first opened it up, there was a frikkin drop of spilt solder on the cell too
My MS sport came with a standard 50 mah, and I haven't opened up my ZZ SE(don't have my precision screwdrivers with me
)
