@mntmn tbh i don't remember already and looked through all my past order history for last 3 years i cannot see it. Found only white 100A 5S BMS but i use it for different battery assembly. For that box I remember was using green pcb 20A 4S LiFePO4. It was 4s2p assembly so both packs wired in parallel to 4S terminals (to 12V power rail)
@mntmn but it is very simplistic box tailored to fit the free spot in the closet, with 2.5mm barel jack for power (to plug right into PoE switch barel socket). BMS+balancer in the middle and holders in side slots. a cap just with hole for the barel jack and socket.
@mntmn using in it for couple of years in my wiring closet at home as emergency power backup for network equipment.
