looking for repalcement Li-ion 3.7 V150A?

[picard]

I am looking for replacement Li-ion batteries for my wolf eyes 3.7 Volt 150A battery.
What is the appropriate replacement battery for the 3.7 V 150A battery?

I currently own the wolf eye 9M Cobra Xenon flashlight that uses 2x 150A batteries. The batteries don't seem to hold charge for long time. I am looking for 18650 battery as an alternative.

Does the 18650 battery have same size & voltage as 150A?

Hello Picard,

The 150A is the same as an 18500.

I believe you can only replace a 150 battery with another 150 battery. An 18650 has the same voltage but is a larger size. You might ask on the Incan. forum if Wolf Eyes has a battery tube extension for this light to fit 2 18650 batteries.

If you are looking for a less expensive alternative there is only 1 and that is an AW brand protected 18500 li-ion cell.

There are MANY 18500 cells on the market, but there are only 3 brands selling protected cells of good quality that have high current thresholds set on the protection circuit. That's Pila, Wolf-Eyes, and AW. Pila being the priciest, they call their 18500 cell and 300P, the Pila cells are also arguably the best performing, Wolf-Eyes as you know, calls their 18500 cell a LRB-150A and are priced just slightly under the Pila, and AW, who calls it what it is, an 18500, has the most value oriented price IMO... Check the dealer section of CPF marketplace and find AWs li-ion sales thread (it's almost always running in the first dozen threads or so, heavy activity there)

If you search around on the net, you will undoubtedly find numerous sources of 18500 cells for VERY cheap. Do not be fooled, many of these are unprotected (bare) cells that should not be used in a circuit like a flashlight (with no built in cell monitoring), and many protected cells available will not light up the bulb reliably.
