Metal-box batteries in catalogue view: Litio Store LiFePO4 at 12V 200Ah with a 200A BMS and 2560Wh, Ultraslim series with metal enclosure, also available in a promotional version.
The difference between an ABS plastic box and a metal one is mechanical strength and behaviour in a fault: a metal enclosure takes impact and sustained vibration, does not deform with heat and contains a thermal event better. On work vehicles and fixed installations in plant rooms it is the one to choose.
The Ultraslim format keeps the thickness down, so it fits bays a standard 200Ah box would never go into.
