State of charge indicator: 4 bars in the battery symbol:
• 75 to 100 %
• 50 to 75 %
• 25 to 50 %
• 0 to 25 %
In charge mode, the upper LED line inside the battery blinks indicating the charge phase:
• 1 time: bulk
• 2 times: absorption
• 3 times: equalization
• permanently on: floating
For lithium batteries with BMS, the upper line never blinks as there are no charging phase controlled
by the next3. The charge is controlled by the BMS.
Special cases:
• If there is absolutely no light on any of the LEDs, the next is completely without power (battery
disconnected) or there is a problem with the display of LEDs.
• When powering up the next3 with the battery, all LEDs blink once during the start check.
• All LEDs can blink at the same time in an identification procedure (with nx-interface). It is
possible to identify the devices in multi-unit system that way:
