K5 power supply issue with lithium betteries, and overall usage.
Seems there is an issue with the power supply for the K5, it’s constantly on, and creates a parasitic drag on the battery. Bought new power supply for the K5, thought the old one was broken. Same issue. Had to buy third party power hub due to that issue, as lithium batteries do not have the same capacity as led ones. When i had a lead-acid battery this wasn’t an issue.
I have been using k5 for as long as its out (5 years). It’s a great camera.
Most important future is 60fps, and 2k resolution. For a fast sport bike the 60fps is crucial due to speeds. 30fps doesn’t cut it. Have also the C5 camera, it’s good but for slower rides, I use it on a 125cc, and it does the job for those speeds.

Hi Maciej,
Strange that you had a power supply issue because of the type of battery you are using. The capacity of a battery should not affect the battery voltage. With a lead, AGM or lithium battery, the voltage should always be around 12.5V – 13V.
And yes, it is indeed a great camera. I have had it in my BMW for years. In the BMW I have an AGM battery (2024). With a K5 and a K3, both with parking mode active, and an alarm system I have no problems with draining the battery. I can easily leave the bike parked for 4 weeks and then the parking mode still works and starting the engine is no problem.
I have the resolution set to 4K30 + 1080P30 and the bitrate at maximum.
Up to speeds above 200KmH, the image quality is still good for me. -
Well, that’s not exactly true. If the battery is discharging constantly the voltage drops. For lead-acid, below 12V is dead. Lithium have mostly build in safety around 12.5V. But the voltage drop when battery is drained from around 14V (depends on battery) . So You can tell how much a battery is drained and if needs replacement based on voltage and capacity (no capacity and low voltage = dead battery).
As for the power supply, the led is always on, and that’s not an issue, but when You check current and voltage, the unit supplies the 5V voltage for the camera constantly. The circuit is not disconnected regardless of ignition (the yellow control cable – ignition 12V ).
