Charger for multiple Li-ions

[vrocco]

I already have 2 of the Ultrafire Quick Chargers for Li-ion batteries. Is there a charger out there that will charge multiple Li-ions at the same time.

I am thinking a charger with space for 6-8 batteries that could charge CR123, 10440, 14500, 18650, etc

Anyone know if such a beast exists?

Any hobby charger that handles Li-Ion (with sufficient charge current) can be used to charge multiple cells simultaneously. Biggest issue is putting together a charging cradle. I use this to charge eight unprotected 16340 cells in parallel:

You can probably do something similar for 10440 (AAA) and 14500 (AA) as battery holders are available for those sizes. I have not yet found a good solution for 18650 in more than 2 cells.

When charging cells in parallel, ensure that their state of charge are reasonably close to each other.

I was hoping for a commercially available solution, but I'm guessing that doesn't exist.

Why has no one developed something like this yet? I'm guessing all you guys have a ton of li-ions laying around at any given time. I can buy a NiMH charger that will do 12 cells at once, why not one for li-ions with spring clips like the Ultrafire Chargers so it fits everything from CR123 to 18650??

Basically because other than R/C and flashlight hobbyists, no one else has a clue about these Li-ion cells.

The market is too small to invest the R&D into something like that.

The R/C guys have the hobby chargers and a fair amount of flashlight folks use them as well.

A link to my monster charger for 12x 18650 is series is in my signature. (It will also do 16340s and quite a few other cells with spacers.)
