Daly 19S-1Amp

Daly 19S-1Amp Active Balancer is a powerful and efficient battery balancing solution, designed specifically for 19-cell lithium battery packs. Whether you’re building a battery system for solar energy storage, electric vehicles, or industrial use, this device ensures your battery cells remain balanced and protected—ultimately improving performance and extending battery life.

Unlike traditional passive balancers, which dissipate excess energy as heat, the Daly 19S uses active energy transfer technology. This means it intelligently redistributes charge from higher-voltage cells to lower-voltage ones, resulting in a more balanced battery pack. Consequently, this helps prevent overcharging and undercharging of individual cells, which are common causes of battery degradation.

Moreover, the Daly 19S balancer features a 1A balancing current, making it ideal for medium to large battery systems where faster balancing is essential. Even during charging and discharging cycles, it works continuously in real time to maintain voltage uniformity across all 19 cells.

In addition, this active balancer supports various lithium battery chemistries, such as Li-ion (3.7V nominal) and LiFePO₄ (3.2V nominal). It is compact, lightweight, and easy to install—perfect for both DIY and professional energy system builders.

Furthermore, the balancer comes equipped with reverse polarity and over-voltage protection, enhancing both safety and reliability. Thanks to its intelligent design, this unit is not only efficient but also long-lasting, making it a smart investment for anyone working with high-voltage lithium batteries.

To summarize, the Daly 19S-1Amp Active Balancer offers a reliable, energy-efficient, and safety-focused solution for keeping your lithium battery packs healthy and well-balanced.
