Figure 15. Three Lithium batteries in parallel with external relay
OK: Equally divided battery current.
All batteries contribute equally to the current into the load.
NOT OK: Current not equally divided.
Batteries closest to load will have the highest contribution to the current into the load.
Whereas batteries further away from load will have lesser current contribution.
Wear and tear will be higher on the Lithium battery close to the load.
When using Lithium batteries in parallel configuration CAN balancing is not required.
4.6.5. Connecting Lithium batteries in series and parallel
Caution! Before connecting 2 or more Lithium batteries,
the Lithium batteries must be charged to 100% SoC.
Caution! For more than 4 Lithium batteries in series and
parallel connection consult Whisper Power or your dealer.
Caution! Depending on the installation a precharge circuit is needed. For further
information consult WhisperPower or your dealer.
