RCR123A 3.0V 900mAh Rechargeable Li-Ion Battery and Inova x02?

Does anyone know if the Tenergy 3.0V batteries will work in the Inova x02?

RCR123A 3.0V 900mAh Rechargeable Li-Ion Battery

I am hunting for a rechargable solution for this kind of flashlight and I have another application, but I am curious if someone else has tried this before I do.

I know you can't use the standard 3.7V rechargable cells. Because just off the charger they are 4.2V and that is too high for this light.

My application is for the X02, but I also want to use these cells the same way for an RC airplane.

These cells charge the same. They drop to 3.2V - 3.0V 100ms after load is applied. So I was wondering if this is too much for the X02, and if it is, this might also be too much for my RC airplane load.

They'll work just fine in a X02 and most LED based lights. The PTC kicks in at or around 1.2 Amps, which coincidentally is what most 2 CR123 incandescent light draw. I've used those batteries in 1 (Q3/Dorcy S1W), 2 (X5), and 3(Pelican 3370) cell LED lights, and they seem to work just fine. They will not work well in any of the incandescent high intensity lights.

I think it was Matt from BatteryJunction, who says he has some sort of financial or IP interest in the Tenergy brand, that said that the 900mAh batteries have a capacity of about 750mAh, and the 750 versions were around 600mAh.

Thanks brighteyez. That was the answer I was looking for.

I saw that the light might work, but I have already blown 1 up like this when they first released the rechargable cells and no one knew if they blew the lights or not. I just did not know if the new ones do. This means I should be able to use 2 of the 3.0V cells for my reciever in the RC plane and be good too! YEA!

Any idea if the regular chargers should work with the Tenergy cells?

 

[Brighteyez]

As far as I know, you need to use the charger that is specific to these batteries, and they do specifically say not to use the 4.4V chargers for either the 900 or 750 mAh 3.0V batteries.

The charger doesn't cost much ($13), I'd just play it safe and get it rather than risk damage to the batteries or your existing charger, or getting all sorts of toxins all over your garage if the thing blows up. Unfortunately, I don't think that charger works with anything else.

And if you're going to pick it up at Tenergy, they're over by the Sunnyvale Costco, off of Lawrence. The last time I called them, they said to just walk-in, no need to call-in your order in advance.

I was sold a 4.4v charger with my "900 mah" Tenergys.
What am I supposed to use?

The charger that comes with the cells.

Please do not mix/match chargers and cells. The 900 charger will not charge the 750 cells. The 750 charger will charge the 900's but too slowly and we specifcally recommend against it.

FYI - The 'loose' chargers I sell are the correct ones for the 900 cells, not the 750's.
