Product overview
The Grepow GRPA290190 is a high nickel semi-solid state battery cell for integration into electrical power systems. Its applications include agricultural spraying, industrial patrol, mapping and logistics drones, alongside manned aerial vehicles and portable energy storage. The cell combines a nominal voltage of 3.7V with 28000mAh capacity and a 5C discharge rating. Energy density reaches up to 350Wh/kg, while the stated weight reduction is 27% against ordinary batteries with the same number of strings and capacity.
The physical integration envelope is 9.9±0.3mm thick, 89.5±1.0mm wide and 189.0±1.0mm long, with shape and size customization available. Construction features include a complex-coated separator and silicon material with over-discharge resistance at 2.5V. Charging cut-off voltage is 4.2V, and capacity retention is over 80% after 1100 cycles. An intelligent BMS protection board is optional. Separate pack solutions offer 6S, 12S and 14S configurations with 16AH-84AH capacity options; these are configuration choices beyond the specified individual cell.
