Product Overview

The SOARLID SLD4-6S37Ah is a 6S 21.0V 37Ah semi-solid-state drone battery from CGBT’s SLD4 series, built on 436Wh/kg semi-solid-state cells. It stores about 777Wh at roughly 1.95kg and is designed for VTOL fixed-wing, mapping and long-range multirotor drones where flight time per kilogram is the priority.

The 1.5C continuous / 5C peak discharge rating is matched to efficient endurance cruise. The reference build uses an XT90 power plug and XH-7P balance plug; leads, connectors, case design and BMS communication protocol can be customized to your airframe. Contact CGBT for the full datasheet, sample lead time and OEM pricing.
