Assembly required. 1/4" thick acrylic case kit comes with glue and instructions. Case only, bars and cells not included.
PDB bars have the balancer lug on the bottom, there are groves cut in the base of the case for the lugs and screws to fit into so the bank sits flat- or you can pre wire the bars with the wires on the top side of the bottom plate. You can purchase PDB bars here.
24ah and larger cases now have a mounting location on the lid for a 4s LFP balancer.
