Battery Protect reverse input

Is it possible, that the Battery protect gets input current at it's output connection (approx 60A) from a second charger (B2B), to load leisure-batt while driving?

so it will be possible to install battery protect between battery and distributor bar. The B2B charger would be wired (and fused) ober the distributor bar.


Thanks

For anyone coming to this thread in the future with this question:

No, the BatteryProtect and Smart BatteryProtect are unidirectional devices and it is forbidden to connect them in a manner in which reverse current could flow through them.

Please see the user manuals for permitted connections.

[updated to remove possibly misleading info]

Pushing current in reverse through the BP is not blessed by Victron perhaps for the power issue or possibly other reasons unknown.

See this thread (exact same situation, even if it doesn't immediately appear so): https://community.victronenergy.com/questions/2030/vebus-bms-with-2-battery-protect-alternative-layou.html
