I like the addition of the over-discharge protection module. As always, a perfect construction!
Maybe you could add a pot to control the backlight brightness, it also saves some mA which is good for battery operation.
Its a shame, my units still haven't an enclosure
Hello hornycz,
as far as I know all UltraFire Cells and however they are called only provided a fraction of its rated capacity. So do not be surprised if the battery does not last as long as calculated.
It says 9800mAh, if it has 2000mAh you can be glad.
I have once made some tests at work witch those cheap china cells, because we have there the equipment to make benchmark tests.
Regards, engolling

Yes, surely you are right. Their advantage is that they are very cheap.
I just need a UPS feature from this battery, the display is powered constantly, but sometimes there is a power
failure (on the other hand, it is a matter of minutes). So life in general do not care, but if necessary can be exchanged
for a better battery.
Thank you for your note!
