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?.
