Dc Load Connected - Discharge Protection; Parallel Battery Use - Tab LiFePO4 User Manual

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 TAB LiFePO4 battery close to the load.

4.7. DC Load Connected - Discharge Protection

TAB LiFePO4 batteries are as standard equipped with a DC switch-off device which is
integrated inside the battery, which is activated at 80% discharge.
However, we recommend to install a bi-stable latch relay which should be installed
between the battery and the entire DC load (or inverter) as an extra security.
Ask your dealer or supplier for the right device.

4.8. Parallel Battery Use

• 6V batteries can be connected in parallel up to 20 pcs;
• 12V batteries can be connected in parallel up to 20 pcs;
• 24V batteries can be connected in parallel up to 20 pcs;
• 6V batteries can be connected in series up to 4 pcs;
• 12V batteries can be connected in series up to 4 pcs;
• 24V batteries can be connected in series up to 4 pcs;
Caution!
Please sort the voltage and internal resistance of the battery
blocks before make the connection. To make sure the battery blocks for a battery
pack have the same/similar parameters.
