4S Battery Voltage Display or Replacement Shell

View individual series-group voltages in a compatible four-series battery setup with the 4S display option. It is for builders checking the battery wiring and voltage range before connection.

• ✅ Read separate group voltages — The display version collects four-series battery readings.
• ✅ Check the pack total — The display provides a total voltage reading.
• ✅ Change the viewing orientation — A switch flips the display direction.
• ✅ Replace only the casing — The shell-only option excludes the measuring electronics.

Choose a display or the shell you need

Use the voltage-collection version only with the wiring arrangement and electrical range specified for the exact unit. A shell-only selection is a replacement enclosure, not a working tester.

This product is not automatically a battery balancer, charger or BMS. Confirm the allowable cell chemistry and voltage before wiring and do not assume the display's resolution is calibrated accuracy.
