High Battery usage with 6.47 stable

On thing may create problem for you. You have added lan IP on an interface and not an bridge.
You are not the first and for sure 100% not the last one to make this error.
DHCP server is correctly configured on the bridge, so why did you miss the main IP?
I guess you have upgraded from an older version <6.44

You can upgrade the Splunk script to get more information. You are on 3.2, latest 4.0 found here with CAPsMan support:

Also you should remove your email from the above post. Its listed under /tool e-mail

Second router config is this set correctly.

Wrong

/interface bridge port
add bridge=bridgeLAN comment=defconf interface=ether2-CAPsMAN
add bridge=bridgeLAN comment=defconf interface=ether3-LAN
add bridge=bridgeLAN comment=defconf interface=ether4
add bridge=bridgeLAN interface=wlan2GHz

/ip dhcp-server
add address-pool=dhcp disabled=no interface=> bridgeLAN > lease-time=1d name=
defconf

/ip address
add address=192.168.0.1/24 interface=> ether3-LAN > network=192.168.0.0

Correct

/interface bridge port
add bridge=bridgeLAN comment=defconf interface=ether2-CAPsMAN
add bridge=bridgeLAN comment=defconf interface=ether3-LAN
add bridge=bridgeLAN comment=defconf interface=ether4
add bridge=bridgeLAN interface=wlan2GHz

/ip dhcp-server
add address-pool=dhcp disabled=no interface=> bridgeLAN > lease-time=1d name=
