All about the product
A reliable compact device that ensures the long and trouble-free operation of 12V battery sets
Automatically equalizes voltage differences between batteries, protects against damage, and prolongs their lifespan, ensuring stable and safe operation of 48V devices – all in a compact, fire-resistant housing that is ready to work in any conditions. Does not require connection to a 230V mains, operates completely autonomously, drawing energy from connected batteries . An ideal solution for demanding and long-term applications – from photovoltaics to electric vehicles.
Key features and technical specifications
• Automatic voltage equalization between 12V batteries in 48V systems• Maximum equalization current: 10A
• Built-in reverse polarity protection
• 50 cm long connection cable with M8 terminal – ready for immediate installation
• Supports: 4 batteries 12V – both lead-acid (AGM, GEL) and LiFePo4, NCM, LTO
• Display indicating the device's operation
• Recommended battery capacity 20Ah – 200Ah
• Powered directly from the batteries – does not require connection to a 230V AC mains
• Highly accurate integrated circuits reduce component deviations
Real-time battery voltage monitoring
The voltage balancer features four clear displays that show the current voltage of each 12V battery operating in a 48V system . As a result, the user can easily monitor the condition of the set and quickly notice any possible voltage differences between batteries . The displayed values facilitate the assessment of the device's operation and allow checking whether the voltage equalization process is proceeding correctly.
How to connect the voltage balancer
Before connecting the voltage corrector, make sure that both batteries are fully charged, of the same type, and of equal capacity . The voltage difference between them should not exceed 0.2V. It is also very important that the batteries are properly connected in series, and the total system voltage should be approximately 48V. Connecting the balancer is simple - just connect the black wire to the negative, the red to the positive of the entire 48V set, and the white to the point between the batteries – the balancer will take care of the rest. The device will turn on automatically, and the LED indicators A and B will inform that the system is working and taking care of your batteries .
For camping, yachts, photovoltaics – Compatible with AGM, GEL, LiFePO4, NCM, and LTO batteries
The 48V voltage balancer is an excellent choice wherever you use two connected 12V batteries in series. Perfect for campers, trailers, boats, solar systems, electric vehicles, forklifts, and backup power devices . It operates seamlessly with lead-acid batteries (AGM, GEL), as well as with lithium types such as LiFePO4, NCM, or LTO . This small device can significantly extend the lifespan of the entire battery and prevent costly failures.
