When to use the Active High and Active Low on Smart Battery Protect with Smart BMV-702?

I am struggling to understand when to use the Active High and Active Low on SBP with Smart BMV-702.


I have a SBP 220 as charge disconnect connected to solar and vehicle starter.

1. Would I connect the "L" or "H" to the BMV-702 from SBP ?

2. Would I connect to the Normally closed(NC) or Normally open(NO) on BMV-702 input?

Can you please explain your answers.

*The BMV-702 itself is connected by COM to VE.BUS BMS "Charge disconnect" input.

Hi Mike, what are you trying to achieve? Reading your post, the BatteryProtect is connect to the relay contact on the BMV 702. What criteria have you set to operate the relay?

Hi David,

The SBP100 is Lithium mode and SBP200 is in relay mode.


What I am trying to understand is, the remote on the SBP labeled "H" and "L"

How do they work ?
