Rechargeable battery for 2-123 lithium lights?

Could someone just give me the short specifics about what, where, how, and how much a rechargeable battery would be for a light like a SF e2e? Oh, charger too, please.

Thanks very much.

Hi sotto
The only rechargable i know of that fits without modifying is the Pila 168s. The only downside to this is the voltage is only 3.7 volts, so it wont be very good with the MN03, which requires 6 volts. The easiest (but not the cheapest) way around this would be to buy a KL1 or KL4 bezel, which both contain electronics to boost the voltage to the required level.
If you're still interested, click on the URL in my sig, he sells the batteries and chargers. The site also has useful information regarding what lights these batteries will fit and run in.
