Can you charge LiFePO4 3.0V CR123 rechargables in a regular li-charger?

[Lobo]

I was considering getting a couple of LiFePO4 3.0V to run in a flashlight. But realised that a regular li-charger stops at 4.2V, which would be too much. Is there someway I could time it etc, to safely charge the 3.0V cell in a regular charger?

Thanks.

Do _not_ randomly use various Li-Ion chargers with various Li-Ion cells just because the cells happen to fit in the charger!

The problem of having to match up Li-Ion chargers with the correct Li-Ion cells is a weakness of the Li-Ion system. You are essentially trapped into using the charger that was intended for use with those specific batteries. Timing a charge does nothing to help. Why? Most Li-Ion chargers employ a voltage and current limit charge control system. ie: If, upon insertion of a Li-Ion cell, the voltage sensor indicates a charge is needed, then the cell is charged via a current limited control until the proper voltage is reached whereupon the system switches to a voltage limit control. Various chargers use various current and voltage set levels. The chargers and cells really need to be matched!

nope sorry, you need charger designed for LiFePo4, Hyperion EOS 606i (130USD) and Imax B6 (70USD) can handle LiFePo4 and all other type of batteries.

Ah, thanks for all the answeres. Guess there aint no quick shortcut that I was looking for.

i ordered those but they are on backorder

to lower the voltage by 0,5 volts you need a diode and this indeed looks like a diode

however most chargers charge with 450-500ma which is to high(you need 200-250ma for lifepo4 3v aa's))

so if this is only a diode you will also need a resistor in serial to limit the current(probably 1 ohm)

i would have tested this but am stilll waiting on these as well as the charger

once i got them i will post my findings

** double post**

The hyperion 5i AC/DC can do it too (the 12v, non AC/DC version can't).
