HMAS Fremantle
HMAS Fremantle (my first build and is still a work in progress) is a semI kit, hull and some fittings were supplied, most parts have been scratched built. She is powered by two MFA RE-385 5-Pole DC Motors, each controlled by a Mtroniks MicroViper Marine 10 ESC, supplied by one 6V 3.4 Ah lead acid battery, she has a running time of approx 90 minutes on the lake.

Sorry I can't answer that, I've never used lipo's so I can't give you a comparison. I've never had any problems with the sealed lead acid batteries, and use them on all my boats, they also double as ballast, as I would rather use batteries that dead weight.
