Low battery warning - pointless
CompletedI have a Karoo 2 and it gives a low battery warning when devices have plenty of battery life left. My bike gives a warning at about 50% charge and my Varia Radar gives a warning very early on - no idea of the percentage but it's no where near low. Can this be addressed as it means the warning is pointless and of absolutely no use at all. Either turn it off or make it accurate and warn at 30% or something.
A week ago I bought a Hammerhead HRM and have used it for roughly 8 hrs. Today it gave a low battery warning, I don't have it connected to anything else other than the Karoo 2 and it is supposed to last 900 hrs. Complete waste of time.

Are you talking about the Karoo battery itself? If not, maybe mine is faulty then. I get low battery warnings as notifications for attached devices like my bike. When my bike is around 50% I get a low battery notification - it varies though and is not consistent eg yesterday the warning came at 45%. Other devices I cannot tell what exact percentage they are at as there is no reading eg my AXS battery or Garmin Varia or indeed my Hammerhead HRM. The HRM gave a low battery warning today after just 8 hrs use, it is brand new and supposed to last 900 hrs, so a low warning at 99%!!!

Hi James, we have received your details on the ticket to the support team. We will look into your device log and history and provide you with the solution. eBikes can have different threshold for their low or critical battery level, so we will have to look into that. As for the sensors added on your Karoo 2, try disconnecting and adding again if you haven't done till now.
For the HRM, do you remove the HRM pod from the strap after the use, we suggest doing that for a longer battery life. https://support.hammerhead.io/hc/en-us/articles/1260803482709-Karoo-2-Hammerhead-Heart-Rate-Monitor -
Hi Ali
Thanks for your reply - I am disconnecting the HRM from the strap when not in use and the HRM is less than a week old in any case. Also I am not using it via Bluetooth either just the ANT connection to the Karoo. I have readded the sensors more than once.
The bike itself does not warn of low battery at 50%, just the Karoo, so it's not the bike threshold that's the problem. The bike has a critical at 10% I think and low at 30%.

Any progress on this? I have an arm bad heart monitor showing a low battery level on the Karoo 2. I fully charged it, reconnected and it is still showing that it is low battery. Connecting to the HR monitor app on my phone shows it is 100%. I don't feel like this should be that difficult?

I am also getting low battery warnings for connected devices when the device is at only about 50% of battery life. This happens for all kinds of devices, SRAM AXS shifter batteries, Coros Vertex 2 watch, & my S-Works Turbo Creo internal battery. It is pretty annoying that the Karoo thinks the batteries in those devices is low when they really are not.

@Marcus Hecht Today's s Software Build Version: 1.464.1818 - release notes says:
We’ve improved the behavior of the “Low Sensor Battery” alerts that appear on Karoo outside of rides. These alerts will now disappear if you acknowledge them or power down Karoo.https://www.eu.hammerhead.io/blogs/change-logs/karoo-software-build-version-1-464-1818

Yes, I did see that - but that still doesn't stop the low battery warnings from occurring at 50% instead of something more realistic like 20% when a battery is truly "low". The threshold for the low battery warnings themselves is just set to high. But I do admit it will be nice to be able to easily dismiss them - but they still shouldn't be warning me of a low batter when its at only 50%.

I was having the same experience (low battery warning for the shifter itself, the CR2032 coin battery not the rechargeable batteries on the derailleurs themselves) but the SRAM AXS iOS app showed the battery was fine. I decided that indeed the Karoo 2 was triggering the low battery warning too early at 50% and not a lower charge as one might expect.
