I just realized that I misread your question when I posted earlier. I have also used a little bit of solder wick to fill that gap when needed, although usually if it’s just a hairline gap 60/40 and a little work usually get it done for me. In my very limited experience I’ve found that 63/37 is much harder to bridge gaps with.
Can you get the driver without low voltage warning/shut-off for use in non-Li-ion lights?
Ordered some 20Rs, gotta see how they compare to the 4.3v 28As...
All it takes is removing the resistor at R2 (marked '4701'). Since RMM offers an add/remove 7135s service I think that would be well within his capabilities. :)
Not at the moment, but I know that the program can be altered to remove this function. Is there much demand for this? I know that lifepo users might find this handy, I guess that it might also be useful to drain the last bit of juice out of NiMh and Alkaline batteries.
Just remove R2 to disable it, nothing in the FW needs to be changed. Without R2 to provide the drain to ground the MCU will always think the voltage is above the low voltage trigger point.
Thanks comfychair! Here I was thinking about reprogramming individual drivers when the solution was this simple! 
Thanks, that should be very doable. Even easier than a resistor mod to eliminate next mode memory.
Received my batteries today, thanks for the quick shipping.

Efest 10440, nice.
Would you have prices for them yet?
Easy…wrap them in foil. Device? Expandable tin-foil hat. :party:
I can give you a ballpark figure: around $3.50 each (without any shipping costs added). I think that I am going to go to an actual shipping cost system in the near future, which will be more advantageous to those looking to buy just a few different cell types in the same order.
Received my package today, Thanks!
The 20R’s and drivers were packaged nicely, no problems what so ever. Really appreciate it and already have a driver stacked and installed. 
Take 5% off of your total order! From now until 11:59 p.m. EST 11/11/2013.
No coupons or codes needed.
Nice deal!
Question... do you know at what point the protection circuit would trip on the 18650PF Protected batteries? The usual 5A?
That’s a good question. My SRK pulls over 7.5 amps from four cells. Let me get a PF charged up and I’ll see whether it trips and if not what current it allows.
Thanks for checking!
This is a good deal.
order placed!
My FT order was returned to sender. All battery orders will just have to be done local.
Better off.
Thanks!
I just tested with my SRK. It pulls around 7.9 amps from the single cell for 2-3 seconds before the circuit cuts power. It seems to reset itself after a few seconds. I repeated this test several times with similar results. I don’t know where the actual cutoff point is, but it is below 7.9 amps. I also know now that this cell can put out a lot of power even with the protection circuit; i.e. the protection circuit isn’t adding much resistance.
