Mount for PowerSport batteries on Blackhawk lowboy quad ppg.

A mount for PowerSport batteries on my Blackhawk quad wheeled para-glider.
I made this to replace the original NiCad pack with higher current Lithium motor cycle batteries.
The mount clamps onto a 25mm frame tube.
The batteries are much larger but about the same weight as the nicads.
It is a centre tapped 24V system.
The new batteries are rated at 140 Amps cold cranking.
