5x LiCo cells--64656. 64655 or 64458 or *gasp* LED?

Running 15 of these guys in a 3P5S configuration, which lamp should I go with for maximum lumens?

Nominal voltage of the pack should be between 18.5 and 21 volts. Current capability (if the cell wrappers are to be trusted) should be 13-20 A.

Any advice appreciated.

64458 will need close to 10 Amps to glow properly and each cell will need to provide almost 3.3 Amps.

Assuming, mentioned cells are real 700mAh, 3.3 Amps is way over the 2C limit.


You can use high drain IMR cells safely.

I see conflicting info in the auciton listed there. Some parts say 2000mah, some say 2200mah

Logically they are around 750mAh.
OP says current capabilty will be 13A-20A.
For 3x14500 LICO cells in parrallell I'd estimate 2-5 Amps current capability.

To the OP - advice is forget this plan!

64458 is the simplest build. 5 x IMR cells. Done. Screaming bright. No softstart required.
Several thousand lumens with a decent beam. This wheel requires no re inventing.

And you can also overdrive the crap out of it. It's very resilient.
