Can this solar panel charge mavic 3 batteries?

[charliebicks]

Hello there. I am going on a jungle expedition in Suriname next week. Three of us are going to be totally isolated in the jungle for about 20 days. We will have to kayak about 200kms and cut our way 30kms through virgin jungle to reach the Julianatop, tallest peak of Suriname. Being able to use the drone at greater will be helpful to our expedition.

I bought this solar panel because the voltage seemed enough to be able to charge the intelligent flight battery.

The battery states that it’s nominal voltage is 15.4V and it’s max charge voltage is 17.6V.

Supposedly the solar panel can generate 80W and the voltage through the usb c is 20V, and through the DC port is 28V, though on the back of the solar panel it talks about the open circuit voltage being 24V and the maximum power voltage being 19V.

When I’ve tested the solar panel fully unfolded in direct sunlight via usb c, the panel has not been able to charge the drone battery either in the drone or using the charging which charges all three.

all my batteries otherwise work fine.

Can someone please enlighten me as to why the batteries might not charge?

Perhaps I can charge them using the dc port if I have some kind of transformer?

I am in Suriname already so getting a new solar panel won’t be possible.

Thanks very much.

Charlie

I am not familiar with solar charging a DJI Drone. Don't you need a MPPT? I am not sure.

I know you said there isn't much you can do about it now but I would have brought along a couple good [Anker] power banks and recharge them using the solar panels. The power bank *will* recharge the Mavic 3 batteries. I don't know much about solar panels but they are notoriously over-rated (literally) and you have to use them just right, exactly, to get the max out of them.
