Hey Bill! I appreciate you commenting! Your knowledge and experience in racing (and many other ventures) is well known and respected! Yes, Pat Mccue and the team are running 800 volts (Dual Reinhart controllers and dual AM Racing motors) and I think (he would have to chime in) that running a DC-DC converter complicated the setup so they opted for an isolated 16v battery. The headway pack (16v accessory battery) they made had seen it's day and was not as healthy as it could have been. They did have a lithium specific charger for the headway pack.
So, off to the local parts supplier for a regular old heavy 16 volt racing AGM. Apparently for racing they opt for a 16v battery as due to the heavy loads and ignition systems. I did not know this and learned helping out in the pits. Always something new to know! :) The car is drawing about 40 amps to run all the accessories and pumps. So, it's quite the draw. The team was being pretty careful to charge the 16 volt battery between runs and shutting the battery off while sitting in the staging lanes. It just happened at that point in the day it got lost in the mix. Also, they had not planned on putting in an AGM so did not bring a 16 volt racing charger. Like I mentioned in the pits, well, that's racing! :) The back of the car near the '12v' shut off is an analog style voltage gauge. So, it's pretty easy to see what the 16v accessory battery is doing under changing and draw. Also, it's disconnected from the car when not running. The team has done an amazing job engineering the vehicle. It's quite stunning. Like you mention, this event is something we all go through. I remember with our schools drag truck we had the same problem running a pc680 as our accessory battery and making sure it was topped up after every run. There's nothing more humbling and rewarding than learning from a lived experience! :) Cheers!
