mA of Li-Ion cells

[General Veers]

Anybody know if I make a 7.2v pack out of these batteries:  http://www.thecustomsabershop.com/TrustFire-Protected-36V-880mAh-16340-Lithium-Battery-2-pack-P518.aspx.... what the max mA will be?

FIY.... Trying to drive a Lux V!   Overdrive that is!!!!!

880 mAh if you make it a 7.2V pack or 1660 mAh if you make it a 3.6V pack.

Edit:  You could do a 2 X 2 pack with  4 of them for 7.2V with 1660 mAh.  But that might be too large of a pack for your design.

No... I'm talking purley the amps the cells give off.

You see I want to overdrive the Lux V.  I'm not talking runtime.  I'm talking how the cells will drive the LED


Assuming maH=miliamphers per hour

mA=purley amps

Well, that would depend.... if you used 2 700 ma Buck pucks, you would get 1400ma. If you used 2 1000 ones, you would get 2000.... I don't think you want to direct drive off those Lux v' in any case off those batteries.... And I think Lux V's only take 700ma usually. So if you want to overdrive, I wouldn't dare go over 1000ma... but that's just my thing. And I may be wrong on numbers, someone else can correct me if I am.

I was talking to Nova and that amazing Lux V that he made is at like....  1280mA I think he said.

you won't notice much of a difference between 1000ma and 1280 ma.  Just use the 1000ma buckpuck.  Otherwise you'd have to do the calculations and figure out what resistor you need to deliver 1280ma of current to the led.  The pcb's on those batteries will limit the amount of current you can pull from them,  but they will not regulate it at all,  so you'd end up seriously over driving the Lux V if you didn't use either a resistor or a driver.  Without a PDF datasheet available,  it's not possible to tell what the maximum discharging current limit is on the pcb's these batteries are made with.

Ok.... 1000ma is overdriving it right?

[Darth Xusia]

A lux V is normally 700mA so yes, 1000mA is overdriving.
