Altsmoke Alpha + Lifepo4 Batts?

[Jonner]

I ordered some Lifepo4 batteries from a member here. I want to stack these and vape at 6v with my Alpha. I know it voids the warranty but is it "generally" safe? And if I want to get some cartos for the 6v setup, what resistance (ohms) would you recommend?

#1 rule: NEVER place 3v or 3.2v batteries in a 3.6v charger. Li-FePo4's are 3.2v batteries.

#2 rule: They CANNOT be used with Li-ion chargers and you'll need either Tenergy LiFePO4 RCR123A smart charger or the UltraFire 3.2V & 3.7V Rapid Charger (set to 3.2v)

Battery safety is all in how you handle them and all are potentially dangerous, however this battery is considered one of the safest. This is the information on the battery:

Lithium iron phosphate (LiFePO4)

Lithium Iron Phosphate will become the preferred battery technology for traction purposes and other situations in which high discharge characteristics and cycle life are important. Lithium-iron-phosphate (LiFePO4) batteries are based on the original lithium-ion chemistry, but LiFePO4 is used as the cathode material instead of lithium cobalt dioxide (LiCoO2). The latter is found in the most commonly used batteries in laptops, cell phones, MP3 players, etc.

LiFePO4 is an intrinsically safer cathode material than LiCoO2 since exothermic reactions cannot occur in batteries based on this material:LiFePO4 cells do not incinerate or explode under extreme conditions. In addition, LiFePO4 cells have a higher discharge current, are not toxic and have a much higher cycle life than LiCoO2 cells.
Safety

LiFePO4 is an intrinsically safer cathode material than LiCoO2 and manganese spinel. The Fe-P-O bond is stronger than the Co-O bond, so that when abused, (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration. Only under extreme heating (generally over 800 °C) does breakdown occur and this bond stability greatly reduces the risk of thermal runaway when compared with LiCoO2.
As lithium migrates out of the cathode in a LiCoO2 cell, the CoO2 undergoes non-linear expansion that affects the structural integrity of the cell. The fully lithiated and unlithiated states of LiFePO4 are structurally similar which means that LiFePO4 cells are more structurally stable than LiCoO2 cells.

No lithium remains in the cathode of a fully charged LiFePO4 cell — in a LiCoO2 cell, approximately 50% remains in the cathode. LiFePO4 is highly resilient during oxygen loss, which typically results in an exothermic reaction in other lithium cells.[4]

Cartos for 6v should be at 2.8ohm and over. A 3ohm Boge seems to be what most recommend. Just remember to take it easy and take short hits.

For a true HV carto these Blank 510 Mega Cartomizers have had good reviews since they are 3.4ohm.

Happy 6v vaping.
