GP PAPS X TIPS & TRICKS
The specific batteries will have firing issues inside the GP PAPS X. The Panasonic's coating isn't according the safety standards for batteries and the black battery isn't an IMR AW, it is a protected AW ICR one with 3 legs and flat top.
From our beginning of mod making, back in 2011, we refrained to use ICR batteries and all our mods have been designed to be used with a kick that also uses AW IMR and Efest IMR batteries, so we recommend only them.
Thanks to a GP PAPS X user's smart addition, both shall work inside the X without any firing issues.
