Regulated power device in vaping means it has power regulation circuitry, buck boost circuitry, dc-dc converter, amp input & output limits, adjustable power output & built in protections, aka not a mechanical.
Everyone has to set their own comfort level/saftey range when using the cells we use.
My personal battery amp drain saftey limits tend to be on the
conservative side.
20a CDR cells 50w - 60w per cell.
25a CDR cells 60w - 75w per cell.
30a CDR cells 75w - 90w per cell.
Many folks routinely push their batteries beyond what I feel comfortable with, the chance of authentic suitable CDR batteries exploding inside a decent regulated power device is slim.
The LGHB series are 30a CDR but only 1500mah, so short vape time between recharge cycles.
If I were you I'd also look into the sony VTC5A, must be 'A'.

Most of all only buy batteries from reputable & reccomended vendors / dealers to avoid counterfeit or re wrapped lesser quality cells.
