Energy storage product for B2B applications
View Details →
Advanced energy storage product engineered for reliable power applications, scalable supply, and global B2B project requirements.
Your ultimate tool for battery care. From quick charging to long-term maintenance and reviving depleted batteries, the BC-200 PRO does it all.

Monitor every detail in real-time! The clear LCD screen shows ambient temperature, voltage, charging current, and battery capacity percentage, putting you in complete control of the charging process.

Charge with absolute confidence. Our charger is equipped with six key protection systems: Short-Circuit, Reverse-Polarity, Over-Voltage, Over-Charge, Low-Voltage, and Over-Temperature Protection to safeguard both the charger and your battery.

An integrated cooling fan automatically activates when the internal temperature exceeds 45°C (113°F), ensuring optimal performance and longevity by preventing overheating during intensive charging sessions.

Bring "dead" batteries back to life! Unique repair and desulfation modes can safely start charging from 0V, breaking down sulfate crystals on lead plates to restore battery health and extend its lifespan.

Perfect for seasonal storage. Once the battery is fully charged, the charger automatically switches to a float/maintenance mode, monitoring voltage and providing a trickle charge only when needed—zero risk of overcharging.

One charger for countless tasks! Ideal for cars, trucks, motorcycles, lawnmowers, boats, and more. Compatible with 12V/24V Lead-Acid (AGM, GEL, SLA, VRLA) and 12V LiFePO4 lithium batteries (2Ah-150Ah). Save money and space with this do-it-all powerhouse.
