Hi everyone,
Trying to plan a new battery deployment for my off-grid cabin.
I'm planning on installing 4x Victron Smart Lithium Batteries - 12V/200Ah - in a 24V system (2p2s)
I'd also like to include a battery balancer to keep the two sets of series batteries balanced. As per the Battery Balancer manual, bridging the middle connections should allow a single Battery Balancer to manage all 4 batteries.
Picture from the manual for reference:
This design makes sense to me, I understand that the midpoint connections must be sized appropriately to handle load should a battery fail. However, the manual for the Victron Smart Lithium batteries mentions that midpoints should not be connected together:
Can someone provide some insight here? I don't understand why the batteries shouldn't be connected like this. Thanks for any help you can give!
