The B&W PRO500 offers energy solutions for professional use.

The PRO500 is splash-proof, shock-proof and vibration-proof. The robust design allows use even under the most difficult conditions.

The durable and safe lithium iron phosphate batteries are fully operational even in demanding temperatures. 

The flexible charging options through solar, mains, car and truck make handling particularly easy. In addition, the units are equipped with an MPPT (maximum power point tracking) system. This maximizes the solar yield when using solar cells.
