I have 2 Mavic Air 2S units that I recently purchased. The brand new one won't charge on my regular multi charger. Every time I put it on there I get LED2 flashing 3 times quickly. According to the manual, it's detecting a short circuit. If I put it on my Fly More combo charger, it will charge normally. My other 4 batteries charge just fine on the multi charger. Is it worth opening a ticket with DJI?

According to the manual, the charger is providing too much voltage. Either get a new charger or just use the fly more charger.

Hi there. Thank you for bringing this query to us. We highly recommend charging the batteries using a recommended DJI charger to avoid any issues. Regarding the said battery, the battery seems normal as it is charging on the Fly More combo charger without any issues. Should you have other inquiries, please don't hesitate to reach us. Thank you.
