You can tailpipe any PV.
This thread is about the tailcap -- the end piece that screws on and holds the batteries in place. New ones have vent holes in the middle. For people with older ones, they are circulating 5 vented tailcaps. While someone is using one of the loaners, he/she can send Jeff their unvented one for the addition of a hole.
Thanks so much for explaining.. So all the new ones will have the holes is that correct? Nice of him to have the loaner parts huh?
Is the hole needed for the change of the carts I take it??or just a improvement made from using the chuck?
thanks again for the help.. (LOL I think I need to know everything..LOL)
