5 Year Extended WarrantyHOPPECKE Sun Power VR M 2V. 2-620 Lead Acid Battery
Sun Power VR M 2V. 2-620AH Hoppecke AGM
Gel-ESS Technology
The construction principle of the HOPPECKE sun | power VR M batteries is based on the use of grid plates and ESS technology. Due to the high energy density, HOPPECKE sun | power VR M batteries have a very small space requirement and thus allow maximum use of the space.
The indicative energy storage at C100 charge rate is: 616 Ah x 48 V = 29,6 kWh
For 24V system the energy storage reaches 14.kWh
