4.8V solution for new 2C mag

richpalm · Oct 26, 2011

Title says it all... I can fit an IMR 26650 in after I've stripped off the wrap. Glued the insulating ring back on the + end so no shorting risk. Works fine with no hack-job sanding or filing.

However, to get max performance I need to bump it up to 4.8V. Any ideas?

Please don't mention boring or machining-no access or money to do so. Same with unaffordable/unavailable/vaporware tailcaps. This must be a simple, no-machining process.

I do know about the small sub-C's that Battery Junction sells-I have four in a 2D that I did-but would require unobtainium parts for a 2C.

Thanks,

Rich

Hey Rich,

It would help if you mentioned what your were powering up with this, but for now here is one solution.

4 of these should fit in a 2 C with only the need for a PVC sleeve and a spring mod.

oops... I'm using it for 7135 drivers, just like this: http://www.candlepowerforums.com/vb/showthread.php?324549

Takes 4.8V to get the current I need, that's why I need a high current cell, and I don't want to go to 6V-too much.

I really like your design on that light. I think that putting the XPGs up on the sidewall of the heat sink was a unique idea.

I agree that although the driver claims to be able to handle 6V its not very realistic. About the only other things I can think of that would give similar voltage to the 4x 2/3A cells would be maybe 4 nicads. http://www.amazon.com/dp/B004J0RZS2/?tag=cpf0b6-20

If your driver is heat sinked, under a load the voltage from 4 of these would probly sag to around the voltage your looking for.

They're AA'd right to the heatsink. (PTS-2)

Thank you for the compliments!

Another cpf user has mentioned that he can fit 4 aaa cells in his 2c mag, so that might be worth trying, in the aim of putting 8 in there in series parallel. It will be tight if it fits at all. I guess there are variants of the 2 body and some aaa cells will be larger that others.
