Not enough voltage to charge a battery by itself. Put 2 in series and use an MPPT charge controller and it will work fine. You could put more than 2 in series depending on what the voltage limit of the charge controller is.
Two with my $13 gizmo limit at 32v almost as good as MPPT? Easier as a portable with two small panels instead of one big heavy one.
Link to your $13 gizmo unit and what it does?
Free shipping. Less than $13 in US dollars. Probably needs a fan attached to the fan connection at max amps so add the cost of a fan.
