Wiring Diagram
The use of battery power or DC adapter power supply, its wiring
method is the same, only the following two differences:
1 Battery power supply support 4S-24S, voltage balancing accuracy
±3mV;
2 DC adapter power supply support 2S-24S, voltage balancing
accuracy ±1mV. The following figure shows how to install and
connect the 24S battery pack:
EK-24S10EB supports cascading use, and at least one battery between
every two equalizers is the "common end of energy exchange". The
following uses the 36S as an example to describe how to install and
connect cables:
