Looking for opinion on this 123 cell/charger combo

[mtrsprt]

Wondering if I should pick up this. Unless you guys think otherwise.....

Combo Kit: 6 RCR123A 3.0V 750mAh LiFePO4 Rechargeable Batteries with a Smart Charger Tenergy 39003

I will also need an 18650 cell or two, and figured this would suffice?

Need them for my O-like 1W 445, and my 400mW 405.

Thank you.

I guess the main question is if you want a 3.0 or 3.6 volt system. Some lasers benefit from 3.6 volts, for example blurays with linear drivers.

Well the 405nm uses one 18650 cell, so what are my options there?

The 445nm uses (2) CR123's.

LiFePo4 are 3.2v common, 3.6v charged... and the capacity is somehow low IMO
but the internal compounds of the battery are much lesser likely to explode like china related batts.
