Any 6V Li-Ion batteries in 17670 form factor?

[LightHearted]

Does anyone know if there exists a 6V Li-Ion rechargeable in the 17670 (2x123) form factor? I'm relatively new to the Li-Ion scene, and it looks like this would be the ideal solution for many regulated lights that run on 2x123.

Thanks,
Ken

many regulated lights that run on 2x123 will run on an ordinary 17670 3.7V, some won't... If such a cell existed, we would know about it, and I have never heard of anything like that.

Actually it does exist. It is a 17500 with a boost converter mounted on the +ve end to yield an output of 6V. However, the runtime isn't too good on the 1100mAH 17500 with the boosted output ( efficiency around 65% ). Max. current is 1.5A. And it doesn't feature a protection pcb which is needed on running from a boost converter ( it will suck the battery dry without you even notice any dimming output ). Plus, it 'll need its own charger.
