6.4 Connect Batteries in Parallel
To increase the available amount of current and capacity, connect batteries in parallel. At most 6 pcs of
batteries can be connected in parallel.
!
WARNING
Batteries in parallel should not have a cycle difference more than 300.
Step 1.
Before installing and connecting the batteries,
ensure that the voltage difference is not greater than 1V
between batteries to be paralleled.
1.
Power the batteries on and use a multi-meter to measure their voltages.
2.
Charge the battery with lower voltage or discharge the battery with higher voltage if voltage difference is
greater than 1V.
3.
Power off all batteries and keep them in off mode.
Step 2.
Connect network cables.
