Each charger is specified as an external, dual-bay unit for S410 main batteries. It charges up to two batteries at the same time and keeps two batteries together for charging and storage. This arrangement addresses locations where both available space and power sockets are limited. The DC output is rated at 13.05 V and 2.4 A maximum. AC input spans 100-240 V. The charger measures 180 mm wide, 160 mm deep, and 72.5 mm high, with a listed weight of 1.2 kg. These stated dimensions define the footprint and height of the external charging unit, while the listed input range identifies its AC power requirement. Both bays are part of one external charger. For S410 setups that need to charge and store two main batteries in one external unit, this charger concentrates those tasks in its dual-bay design. It is suited to limited-space charging areas and locations with limited power sockets. Order GCMCU9 for the S410 External Dual Bay Main + Main Battery Charger.
