Test/review of Fitorch 26350 USB UC20R 2000mAh (Black-Orange)

Fitorch 26350 USB UC20R 2000mAh (Black-Orange)

Official specifications:

  • Capacity: 2000mAh

  • Voltage: 3.7V

  • Charging: micro USB

A 26350 cell with build in USB charging.

Behind the small hole in the black front is a red/green led that shows red while charging and green when done.

The two cell matches fine, but they are not exactly high current cells, it is probably best to stay below 3A.

This is charging with a round cell LiIon charger using 1A current.

This is charging with a USB charger.


The battery looks good for low current applications, but be aware that the USB charger makes the battery 5mm longer.

Thanks HKJ. :beer:

Thanks HKJ. :slight_smile:

I got 2 of these with my 2 fitorch p25 flashlights.
It is nice to know what they are worth. thx HKJ.

Looks like Fitorch adjusted the end-charge voltage with these newer batches.

The old batch Fitorch UC20R had a more pointed button-top, and will overcharge up to around 4.30v (I’ve experienced it, and also some people reported it some time ago, this was the battery that came with the Fitorch P25 flashlight).

This new batch UC20R appears to have a bit bigger and flatter button-top, and charges to correct around 4.20v… (the label wrap of the older and newer batch UC20R looks almost exactly the same)

This was unexpected and much appreciated. Thanks HKJ.

Glad to see this as I was wondering if a higher rated battery would improve output on the P25. I have 2 26350 batteries available to me here, a blue generic unprotected non usb 26350 that claims 6A CDR and a Vapcell 26350 that appears to be the same battery, same specs and 2-3 times the price.

I’m going to try the generic battery.

My top button is broad and flat compared to the photo of this battery on Banggood so I’m assuming I have the updated battery. Thanks for the heads up.

I’m not sure of the actual lumen output, it doesn’t seem like 3000 lumens. I don’t have a way to test it but I’m going to do some comparison ceiling bouncing tonight.

On my new Fitorch USB charging battery
charging and fully charged voltage reads 3.65V. On high/turbo the low voltage indictor light blinks. I thought the light seemed weak when I tried it. I received an unbranded 6A 26350 battery today, it reads 4.18V fully charged and the light is brighter and heats up faster. So I’m guessing the charging circuit on the Fitorch battery is defective. If someone has experienced this or if I’m missing something please give me feedback before I start the CS runaround with Banggood. Also, will it harm the batteries charging circuit if I put it on a regular charger?.

Looks like an unreliable battery brand overall when searching comments on the web. Any other options for protected batteries in that same size?
