Not sure on this, i'll get back to this one.Couple of questions =
1. What does it put out under load with say a 2-2.5ohm Atty on top ?
The sleeves caps are pressure fitted. In the event of battery failure, they will pop off.2. What safety features does it have considering you have to stack Batts which doesnt really appeal to me ? does it have vent holes on the bottom or any slots on the side. What happens if the stacked Batts went into thermal runway ?
Currently we offer to drill a whole in the battery sleeve. The atomizer sleeve is already vented.
Our next batch of units will have vent holes on the battery sleeve from the manufacturer. It will also have an on/off feature on the switch.
