Can’t seem to find a sale on the 7.5A pack I want to use to power kids go kart and Razor mx600 dirt bike. Both run with 1800 watt 48v motors at up to 30 amps. There is a sale on the backpack leaf blower where you can get the 5A battery for $60 but no deals on 7.5A pack. Best I’ve found is $290 new on eBay. Anyone use these packs at up to 30A intermittently or know where a better deal can be found?
