I have a solarforce L2m with the 18650 extension, and it’s hard to find good drop-ins to take the 8.4v. I tried making a parallel 2*18650, but I couldn’t get it to fit and still be safe.
Solarforce brand drop-ins are nice, they are buck drivers with modes and off-time memory, but they seem to top out at 1.5 amps on a good day.
Is there a known way to up the current draw on these drivers? Like a resistor mod or similar? I can most pictures of the inside of the driver later tonight if anybody wants to look at it.
I didn’t purposefully remove anything, but the module stopped working and something fell out. I noticed that empty slot, I just haven’t gotten around to putting it back on.
Do you mind linking me to my own post? I’ve lost track of whatever I said.
I think ~2A is good for this driver. 3A may be pushing it. I have not tested the SF driver on a scope to see where the inductor saturates, but the inductor is awfully small physically. The FETs in use here are not in parallel (do not add their capacity together) and I think they are rated for <3A - and we should keep away from the rating IMO. On mine the Schottky diode is marked SS34 and I think it can probably withstand 3A.
I your travels has anyone come across a 350mAh XML or XPL P60 i have a bunch of old solarforce L2’s with an assortment of old P60 modules. I would like to use them as emergency house lights if i can source P60’s cheap enough, if not in the junk box till i toss them for recycling.
