Will this work?

[mattmagic100]

Hi all,

I'd like to ask for help regarding a battery question.

If I use 3 of these...
Lithium Ion Polymer Battery - 3.7v 1300mAh ID: 258 - $12.00 : Adafruit Industries, Unique & fun DIY electronics and kits
Two in parallel and then connect those 2 with the third one in series, will that be enough to power two 445nm diodes using a Mohgasm 1.25A linear driver (for each one of course).

Thanks for the help!
Matt

What on earth are your plans?

You would be better off with two in series.
The third one is unnecessary.

Three in parallel and a boost driver would also work.

if these are in the same host you will need great heatsinking! and also short runtimes. My m140 in a kryton isnt what gets hot, its the 1.25A mohgasm driver!

Awesome, thank you!

I know, the drivers literally begin burning my fingers. Ill have them very well heatsunk(?) with short cycles, basically momentary.

yeah the drivers start off cool, but after a certain runtime, they get amazingly hot. they can withstand up to 150 degrees celcius before shutdown though. (according to their datasheet)
