HotRod HD, yes I make/ sell a light weight [ 10 lbs] 24 volt remote battery pak, $750 complete with cables and connectors, that we have been using on our JrFuel dragster for 3 years.
I've been thinking of expanding to a 48 volt system for blower racers. I plan on having it at the March Meet.
We have been using a 24 volt charger on ours , and I found a 48 volt charger. The Hayden 48 volt battery Pak should come out weighing about 20 lbs. I'll also look into making a 36 volt set-up, but I've had more calls for 48 volt.
