We're still waiting on some adjustments that were brought out in beta testing. I'm not sure how much of this thread you read over, but there should be some details further back in the thread
ETA: Here ya go Racehorse...
ok an update, the new device is in Beta production right now ( waiting on a few parts ) it is 18mm ( .72 " )in diameter and 120mm ( 4,25 " ) long it is brushed stainless steel with chrome top and bottom caps , 510 top cap that is FLUSH !
it uses 2 x 16340 batts , and has a navigation switch to activate and change voltage as well as LOCK the unit so it will not activate, the display is a full color RGB led display the goes from green to teal to blue to purple to red to indicate the voltage, it will have a brass/SS button to control everything .
I have added one more safety feature a PTC fuse inline with the batts ( positive temp co-efficient fuse ) like are used in batts !
there is a LOW battery indicator ( flashing green led ) over voltage ind. and bad output ind.
