I just revived cells from a NiMH rechargeable pack but haven’t found a light to put them in. Cells are Varta 4/3A, 4000 mAh (17670 size). Looking online I’ve found same size cells for $3.00 to $7.00 (no-name to Sanyo). Has anyone tried this size? I’m considering buying a boost driver and building a P60 drop-in. Any driver suggestions beyond the Nanjg110 driver sold by MTN Elec.?

I’m using those in a 2-cell Solarforce light

right now with LD-30 driver (you can search on that also)
successfully with a Nichia, less successfully with an amber XP-E2
The LD-20 and LD-30 drivers (in several variations) ought to work, but in practice they’re, well, variable.

RMM has a 1-mode NiMH driver; I haven’t put one into a host yet.
He’s been thinking about a multi-mode driver but it hasn’t been built yet, it’s a maybe for the future.
Thanks Hank,
I had already considered the D18 body tube from Solarforce in a 2X configuration. Looking at what drivers are available I’m thinking a low output E-light in a cheap P60 host might be useful. I’ve also thought of buying several cheap AA lights and cannabilizing the drivers.
I use to use them in an unmodified 3T6 type lights. Three worked fine, but 4 provided the best output. Since they are capable of high current, 4 provided enough voltage overhead and current to be just as bright as using normal Li-ion cells.
EDIT: The reason I stopped was because the cells eventually got tired. They were very old when I found the pack to start with. They served me well for a good number of years.
I use the 4/3AF in my direct drive builds.
