The 130g weight spec’d is the the flashlight and head strap together, no battery. I don’t know why they did this, but it’s the only thing that makes sense.
The actual weight of the HD20 with no battery, no clip is 87g, not 130g.
Hey Wurkkos. I ordered the HD20 with the battery and it seems to have a flashing red during a 90 minute charge. The charge indicator never turned green. Via the manual it says the battery is critical so I tried swapping it out with another battery and the problem was not resolved. I ordered the light off AliExpress on 11.11.20. Any advice on this issue would be appreciated. Thanks.
My FC11 is a solid red when charging. I looked around and found info regarding the below. I don’t think my battery would still be below 3% after a hour charge. Also the other batteries tested were running well in other flashlights.
3% > Flashing Red
30% > Constant Red > 3%
Constant Green > 30%
We Tested discharge of HD20 again (batch 1#) different phone and products shows different discharge current, so different equipment will influence the reverse charging current.
A remark : for the turbo i would like the annouced first, ie both flood + throw instead of only the led used befor going TURBO. I will use it on flood for the main part and may need turbo on throw while lost in the wilderness.
It is unfortunately nearly impossible to flash/upgrade the internal firmware. Maybe a few people who know how to get access to the MCU and its pin address translation will be able to modify HD20's firmware. But there is no interface available from the outside.
Please check >>> here <<< to find the updated manual which reflects the actual UI implemented in the first batch of HD20.
