ALSO...for those advocating more or less permanent mountings for your batteries...ROAR also mandates charging batteries in a containment device should a "rapid disassembly" event take place. If your containment device is large enough to accomodate your car you're golden. If your track allows charging LiPos outside a containment device that's their business, but be aware that many tracks do not (ROAR-insured tracks can't, in fact). My own opinion is that USVTA should follow ROAR's lead on this point...we require ROAR-approved batteries, let's also require ROAR-approved charging procedures (including max voltage, etc).
