1. Continue float operation for
1 or a few days (depends on
level of imbalance).
2. Voltage must be above 3.5 V
per cell to have balancing
circuits active.
3. Temperature of the module
must be lower than 55 °C for
balancing circuits to be active.
4. Alarm will be reset
automatically after the cell
voltage difference is within
allowed limit.
5. If fault persists, contact your
local Saft representative.
