OK today did a static run test in my pond using the LIpo albeit not fully charged just 12v and a suspect Lipo
Physical assessment full throttle nearly pulled me arm off
Electric LIpo No throttle 12V
Full throttle drops to 9.8 V and pulling 24Amps
Nimh No throttle 13 V
Full Throttle drops to 8.8 V pulling 18 amps and
me arm still in its socket
are these the sort of variances one should expect
