Appearance Details

628Ah Cells with Pre-welded M8 Studs
Skip the complex setup. These cells come ready for your DIY battery projects, so no welding is needed.

They share the same height and thickness as the MB31, but with double the width for greater capacity in a familiar form factor.

The battery cell will be welded with a single M8 stud

Free Accessories

The MB56 cell comes with everything you need for assembly: flexible busbars, screws, and an epoxy plate. Build with confidence.

Flexible Busbars: Made of nickel-plated copper, offering excellent conductivity and oxidation resistance. With a thickness of 3mm, they can easily handle high currents of 300A without overheating. The flexible material protects the battery cells from damage to the terminals during use.

Package

Each package will contain two battery cells, which will be wrapped in high-rigidity custom foam and transported in a UN-compliant cardboard box.

The two flexible busbars and four flange nuts will be individually wrapped in bubble wrap.
