Need help setting up 64623.

[Drywolf]

Will an Incan pro help me to understand if the setup I want to pursue is going to work or not. I want to drive the Osram 64623 @ 15V and 10.1A per Lux's graph. I have an EleII that holds 16 x 18500 cells in a 4S/4P configuration. I'm going to use a regulator switch to get down to 15V. Since the AW IMR18500 1100mah is rated at 8C max discharge rate, would this configuration draw too much current from each cell?

It does not make sense to me that each cell would be providing 10.1A. I figure it must be 10.1 divided by four = 2.52 and then 2.52 divided by four = 0.63A. It makes sense to me that each one of the sixteen cells would draw around 0.63A.

Anyway I'm not sure what is the right answer. I've read this and that and did not find the answer for myself so I'm putting out the orange cone and asking for help.

Thanks,
Frank

I'm sure fivemega or someone with more experiance than me will post but here's mine. 1100x8c=8.8a. 4P =35.2a. You should end up with a pretty good run time. Arround 25 mins.

Cool, thanks BR.

Does anyone know how many amps each cell will be drawing? Is it 0.63A or there abouts?

You are running 4S4P so each individual cell is drawing 2.52A from each string of 4S of 16.8V (full charge). Simply put - each cell is seeing 2.52A draw which is a piece of cake for the IMR18500.

4S/4P 18500 is same setting as this but I use protected 18500 so doesn't need regulation. Also has little longer run time and I don't have to worry about overdischarge.
2.5 Amp is still in safe range and under 2C

Aw,
Thank you!!

FM,

this

I remember seeing this setup, there is so much information on this forum.
Thank you!!

You guys rock,
