MLI Ultra 12/1250, 24/1250 – User and Installation Manual
* Charging at temperatures below -5ºC / 23ºF may result in battery not accepting charge current.
Temperatures below 5ºC / 41ºF and above 25ºC / 77ºF may affect lifetime and cycle life.
** Due to thermal protection, this high discharge current can be used for 5 minutes at or above an ambient temperature of 25ºC [77ºF].
Battery switch – automatic behavior
CAUSE FOR AUTO SWITCH-OFF
CONDITIONS (for at least 30 seconds)
FOR AUTO SWITCH-ON
• Cell over-voltage
• Cell under-voltage
• Battery over-current
• Cell over-temperature
Cell voltages and temperatures are within safe operating
range
• Extreme over-temperature (> 85°C /
185ºF)
• BMS failure
Battery switched-off permanently
Notes: - If DIP switch 6 is ON, then the auto switch-on feature is disabled.
