Suggestions for Bigger Battery for Leo Rover

Hi, I was wondering if anyone has a suggestion on a bigger battery such as lIpos that do 10500 mAh at 11V. We would ideally like to operate the leo rover for 12 hours or more.

Possibly if a solar cell is doable then we could use that, since we would do the test during the day anyway

Ah, missed the message. Has anyone responded for ex. via email already?
We have a bigger 10Ah battery available. Still not in the shop, but doable on request. There have been some issues with shipping as it’s over 100Wh, but I believe we have it fixed.

I´ve changed to LiFePO4 and use this,
