DALY SOC DISPLAY ROUND

DALY Round Battery SOC and Voltage Display

The DALY Round Battery SOC and Voltage Display provides local battery-percentage and voltage views for a compatible DALY BMS. Its button-operated interface is intended for battery systems that need a simple, accessible status readout.

This display style is useful when a full multi-page touchscreen is unnecessary. The operator can check the available battery indication at the equipment, while the BMS continues to manage the battery measurements and protective functions behind the panel.

The referenced round-module documentation describes percentage and voltage indication, button operation and supported interaction with BMS wake and sleep functions. Percentage and voltage are related but different pieces of information: one is a charge estimate, while the other is an electrical reading for the battery system.

A voltage value alone should not be interpreted as a precise remaining-capacity measurement under every operating condition. Likewise, the display's percentage does not establish that all cells are balanced or that the battery has passed a capacity test. Use the readout as part of the normal operating information for the correctly configured BMS.

Match the actual round display revision to the board and approved harness. The documentation describes UART and RS485 variants, so the presence of those options in the family does not mean that every supplied unit supports both. Identify the actual communication arrangement before ordering or replacing a screen.

Plan the panel opening, retaining method and rear cable clearance using the unit's drawing. Verify the supply requirement independently of the battery's nominal voltage. Where a connector resembles a common consumer connector, follow its documented pin functions rather than assuming that a standard phone charger or computer connection is suitable.

Applications

• Battery panels requiring local SOC and voltage indication.

• Matched DALY BMS systems with a round-display connection.

• Battery-box projects using a button-operated status interface.

• Like-for-like replacement of an approved round module.

• Commissioning checks for display and BMS coordination.

Installation Guide

Mount and wire the display with the battery safely isolated. Use the exact revision's supply and signal connections, and protect the small accessory wires from adjacent power conductors. Keep the face and mounting secure without trapping or sharply bending the cable behind the panel.

Commission the voltage and percentage views and compare them with the BMS data. Check only the wake and sleep operations supported by the approved configuration; a screen button should not be assumed to provide emergency power isolation. Retain the wiring diagram and the display label with the equipment record. Inspect the mounting and harness during routine service, particularly where the battery enclosure is regularly moved or opened. Label the installed communication variant clearly for future maintenance.

Why Choose ARB Accessories?

ARB Accessories supplies DALY battery-management accessories within a wider lithium-battery component catalogue. Include the BMS identification, required display style and installation drawing in your enquiry. Coordinating the screen with its intended board, wiring and enclosure gives procurement teams a clearer specification than selecting a display solely because the front panel looks familiar.
