If anyone is interested, the SCA jump start battery packs at Supercheap are on sale.
Grabbed the last 1900 amp from the Chermside store for $129 to replace my 900 amp after it ran out of power at 2am last night
Should be able to get the night plus some out of a 1900amp i hope

The 900amp is $65.
I believe the sale is Australia wide.
