The FOIF FDJ7 is a professional-grade, dual-slot intelligent charging station designed to provide reliable power management for FOIF land surveying equipment. Engineered specifically for high-capacity Li-ion battery packs used in Total Stations, Digital Theodolites, and GNSS receivers, the FDJ7 ensures your gear stays powered through demanding multi-day field operations.

Key Features

• Dual-Slot Independent Charging: Equipped with two independent charging bays, allowing you to charge two batteries simultaneously or one at a time. This significantly reduces downtime by ensuring a fresh backup is always ready.

• Intelligent Circuit Protection: Features advanced safety protocols, including overcharge protection, short-circuit prevention, and thermal monitoring. This "smart" charging logic preserves the long-term health and cycle life of your expensive Li-ion cells.

• Trickle Charge Technology: Automatically transitions to a maintenance (trickle) charge mode once the battery reaches full capacity, ensuring maximum charge density and preventing discharge while the unit is still plugged in.

• Clear LED Status Indicators: High-visibility LED lights provide real-time feedback on the charging progress for each individual slot, so you can see at a glance when your batteries are field-ready.

• Rugged, Field-Ready Build: Compact and lightweight (approx. 400g) with a durable industrial-grade casing, making it easy to pack in a field case alongside your primary instruments.
