Orbea Rise low battery "mode"

[michael_bc]

I noticed something peculiar during a long day on my 2023 Orbea Rise H10.

I spent the first half of the day in the bike park and depleted my (500 Wh) battery to about 60%.

The second half of the day, I biked up a 2200m peak. Before starting this climb, I attached the range extender to the bike.

The bike first uses the range extender battery. However, somewhere mid-climb, as the range extender battery was almost depleted, the bike switched to some extremely low power mode until the range extender depleted completely, after which it suddenly switched back to full boost mode as it switched to the internal battery.

This power gap was extremely confusing. Has anyone else noticed this?

Is this a technical limitation that the bike has to switch to low power mode as range extender nears depletion to not damage the battery? Or is this a bug in the Orbea software?

just my guess, sounds like overheating instead of low power mode?

I have only once ridden a levo with an extender and it behaved the same as you described, the assistance got lower as the extender lost charge and when the main battery started it delivered full power.
