BORT BC-2 Charger (Updated Version)
The updated version of the BORT BC-2 charger is a technically advanced solution for fast and safe charging of high-current Li-Ion batteries of the Bort ReX 18V series and compatible Makita LXT batteries.
The key change is the introduction of active cooling (fan) in addition to massive radiators - aimed at increasing the reliability, stability of output parameters and durability of the device in professional conditions. The adaptive algorithm guarantees a full charge of the battery while maintaining its resource. Purpose: Slider charger for Li-Ion batteries of the Bort ReX 18V platforms and compatible Makita 18V LXT batteries* (*Note: Not compatible with original Makita batteries due to differences in BMS communication protocols).
Compatible Bort batteries:
Bort ReX series 18V: BA-21Li, BA-21U, BA-21U-62, BA-21U-63, BA-21U-93 (9.0 Ah)
Adaptive charging algorithm:
Maximum charging current: 4 A.
Implements a multi-stage charging scheme (CC/CV) with a final phase of low-current charging.
When the battery capacity reaches 90-95%, the charging current is automatically reduced. This ensures a full (100%) charge of the battery.
Reduced thermal stress of battery elements at the final stage.
Advanced thermal management system:
Built-in cooling fan (new): Added for active heat dissipation from the interior of the charger housing.
Massive aluminum radiators: Integrated into the control board (BMS) for effective passive heat dissipation from the power components and controller.
Practical benefits of improved cooling:
Increased stability and reliability: lower operating temperatures of critical components (BMS, power transistors), especially under intensive use (sequential charging of several batteries, operation in high ambient temperatures).
Maintaining the nominal charging current.
Reduced thermal load extends the service life of electronic components.
Informativeness and protection:
Charge status indication (LED).
Complex of built-in BMS protections:
Overheating protection (charger and battery components).
Overcurrent protection.
Short circuit protection.
Reverse polarity protection.
Overvoltage protection.
Battery deep discharge protection (monitored during installation).
Plug type: European socket
