The unit is current limited to 2.5 amps. Any quality 18650 can put out 5-6 amps continuosly and stay completely cool and within spec. Even with the boost working at max as the battery discharges this still leaves plenty of room. I'm not sure why there is a push for the IMR bats when using 18650's.
I plan on using either the AW 2600 or Panasnonic 2900 mahs for this mod
Hey Nuck-
I think its more of an issue with the 18500's- the AW's max out at 2.4A ... and they would be the battery of choice in a protected format...
Also, I believe the current limit is on the output, not the battery side so if you had to boost and drive 2.5A, the battery drain would be higher- to get to a nice warm 10 Watts (not unreasonable) when the battery is at 3.7V, you'll need at least 2.7A... when the battery voltage drops to 3.2V it needs to pump 3.1A to maintain 10W.... IMR's are probably the only right answer for 18500 if you want to stay within all rated limits all the time..
Also, ECF has gone as far as to say that safe chemistry is safer than a protected battery making LiFePO4 and LiMn chemistry prefered over standard LiCo with a PCB... There's enough evidence out there that tt's hard to argue against it .... I think Provape has gone way beyond in focusing on the safety issues with this device and they set the bar for others to follow. Recommending only IMRs is consistent with that message and I think they are acting quite responsibly by leading with that message....
