Key Feature
- Configured for seven series-connected cell groups, this DALY hardware active balancer is intended to reduce cell-group voltage differences in compatible 7S battery packs.
- Its up-to-1A balancing capability actively moves energy within the battery, giving pack builders a higher-current equalization option than typical low-current passive balancing circuits.
- The dedicated hardware active-equalization format suits fixed battery installations where automatic balancing is required without choosing DALY’s separate software-configurable smart-balancer family.
- A published −20°C to 60°C working-temperature specification gives installers a defined environmental range to consider when positioning the module inside a battery enclosure.
- The exact 7S configuration reduces selection ambiguity for production, repair and replacement work where the number of series-connected cell groups must match the balancing harness.
- Before energizing the module, confirm battery chemistry, connection sequence and cell-group polarity; active balancing complements a protection BMS but does not provide complete battery protection by itself.

DALY Hardware Active Balancer 7S 1A
The DALY Hardware Active Balancer 7S 1A is a dedicated active equalization module for compatible 7S lithium battery packs containing seven series-connected cell groups. It is designed to help manage voltage differences within the battery by redistributing energy between connected cell groups when balancing is required.
Lithium battery packs rarely remain perfectly uniform throughout their service life. Differences in individual cells, assembly conditions, temperature, internal resistance and usage can gradually cause some cell groups to operate at slightly different voltages from others. A dedicated active balancer addresses this condition by redistributing energy within the connected battery instead of performing only simple resistive discharge of the higher-voltage groups.
This DALY product is part of the company’s hardware active-balance module range and provides a balancing current of up to 1A. It is intended to provide balancing as a separate function alongside the rest of the battery-management system.
Key Features
• Dedicated 7S Configuration — Designed for packs containing seven series-connected cell groups.
• Up to 1A Balance Current — The hardware active-balance range is rated for balancing current up to 1A.
• Active Balancing Method — Energy is redistributed within the pack to help reduce cell-group voltage differences rather than simply being converted into heat through a bleed resistor.
• Standalone Hardware Balancer — Suitable when a battery system needs a dedicated equalization module without relying on the communication functions associated with DALY’s smart active-balancer versions.
• LiFePO4 and Lithium-Ion Compatibility — DALY’s hardware documentation identifies the range for compatible LiFePO4 and lithium-ion batteries. LTO should not be assumed compatible with this hardware version.
How It Works
A 7S battery contains seven series-connected cell groups. The balancer’s sampling harness connects progressively from the total negative terminal through each series junction and finally to the total positive end of the pack. Once correctly connected and operating within the module’s specified conditions, the balancing circuit compares the electrical state across the connected groups and transfers energy within the system to help reduce excessive voltage variation.
Compatibility
Use this model only with a confirmed 7S battery configuration. Verify battery chemistry, sampling-wire sequence, connector type and total pack voltage before installation. The correct matching harness should be used for the balancer.
Applications
Suitable, subject to complete system compatibility, for 7S lithium battery packs used in battery assembly and rebuilding, energy-storage modules, solar-storage systems, backup-power battery packs, battery service work, and compatible equipment or mobility battery systems.
Installation & Selection Guidance
Series count is an electrical specification, not merely a naming detail. A 7S balancer should therefore be selected because the actual battery is 7S. Connect and verify the sampling wires before inserting the harness into the module. Incorrect connection sequence can expose battery electronics to the wrong voltage.
The DALY Hardware Active Balancer 7S 1A performs cell equalization. It does not replace an appropriately selected BMS responsible for charge/discharge switching, over-current protection or other battery-protection functions.
