Inova T4 Modding Experience

So a friend of mine has a T4 that he sent to me to fix as Inova won't. Apparently the charging circuit blew and they refused to give him a new one. Pissed he sent it to me (I already built him a one off 3xP4 light for his AR15). Taking these things apart with out totally destroying them is next to impossible. This has got to be hands down one of the worst lights I have ever come across to mod. But if it all works out there shall be a P7 pushing through a Ledil reflector inside a new custom head and bezel. Should be pretty cool if I can pull it off. If not I will just end up throwing a Q5 in there with a buck/boost board and protected 18650. Should be interesting to see how this plays out. Will post pics.
