10.1. Initial charge procedure without BMS

If, for a specific reason, the initial charge procedure needs to be performed without a BMS, this is the procedure for it. Please note
that this is not something we recommend because this process can be risky. A supervisor must be present, who will need to
watch their phone continuously for hours as the battery cell voltages must be checked continuously to safeguard that the voltage
of the highest cell never exceeds 4V.
Charging without BMS is not the preferred method. It can be risky, and a supervisor must be present at all
times.
These are the charger or inverter/charge settings when the battery is charged without a BMS:

Initial charge without using a BMS
Charge procedure:
• Use a battery charger that is suitable for Li-ion, such as a BluePower charger.
• Set the charger to the charge profile as indicated in above table.
• The supervisor connects with the VictronConnect app to the battery.
• The supervisor monitors the individual cell voltages at all times.
