Made a few changes to the dragster over the past few days to save some weight and hopefully improve it overall. I moved the emergency kill switch to the rear compartment which saved 8 feet of battery cable and made it much more accessible for track workers in the event they ever need it...again.
I also removed the PC680 AGM battery that I was using to power the 12v systems and replaced it with a much smaller and lighter alarm backup battery. The new battery is 6Ah and weighs 4lbs.
The major project was to modify the center battery compartment in the chassis so I could move the LiPo pack to it. I removed the old mounting points and fabbed a new battery tray that I welded to the existing structure.
The pack looks right at home in there. This saved 4.5 feet of battery cable which pretty much offset the weight of the battery tray so it's a win all the way around. I had the chassis centered on a jack and moved the pack until it was perfectly balanced from right to left which slightly offset the tray to the right. Having the weight of the pack centered and lower in the chassis has to be a good thing.
Here it is all wired up and ready to rock.
Pretty much looks like it grew there.
Motor is in Cali getting a couple of tweaks. Should be back next week. Hopefully next Saturday we'll be back at it trying to find that 100mph 1/8th mile.
