Product overview

The SOARLID SLD4-6S37Ah is a semi-solid-state drone battery in CGBT’s SLD4 series, built with CGB11075174 37000mAh cells. Its 6S configuration combines a nominal voltage of 21.0V with 37Ah capacity and 777Wh of energy. Designed for VTOL fixed-wing, mapping and long-range multirotor drones, it serves applications that prioritize flight time per kilogram. Cell energy density is 436Wh/kg, while the pack weighs approximately 1950g and measures 66 × 78 × 190mm, with a dimensional tolerance of ±5mm.

Continuous discharge is rated at 55.5A (1.5C), with a 185A (5C) peak for 10 seconds at SOC greater than 50%. Maximum charge current is 18.5A (0.5C), with a 25.8V charge cut-off. Discharge cut-off is 15.0V at T ≥ 0°C and 12.0V at T less than 0°C. Charging operates at 0–50°C and discharging at -20–55°C. The reference build uses XT90 power and XH-7P balance plugs. Optional leads are 10AWG for power and 22AWG for balance, both 100mm long. Leads, connectors, case design and BMS communication protocol can be customized.
