Connectors Motive Power Batteries

MSS Products is the largest UK stockholder of battery connectors used in large motive power batteries used in equipment such as:

  • Forklift Trucks
  • Pallet trucks
  • Electric Vehicles

The connectors are used to connect each cell in the battery together to provide the overall power output of the battery.
The connectors are produced from a specially designed copper cable to give maximum connector flexibility with an acid resistant rubber outer coating. The connector heads are then encapsulated in an acid resistant moulding. The connector head is designed to fit onto the cell pillar giving an airtight seal once bolted into position with the plastic headed bolt, which can also be supplied by MSS.
The connectors are produced from a number of different cable sizes dependent on the power rating of the battery, the main sizes are:


1) 25mm Sq Cable
2) 35mm Sq Cable
3) 50mm Sq Cable
4) 70mm Sq Cable
5) 95mm Sq Cable

The connectors are then stocked in a variety of lengths determined by the centre distance in mm between the bolt holes at each end of the connector.

Plastic Headed Bolts for Motive Power Cells

As mentioned earlier MSS Products also stocks the necessary plastic headed bolts that attach the battery connectors to the cell pillars. These bolts are primarily in sizes:1) M10 x 22mm Long
2) M10 x 18mm Long

The bolts are stocked in both black and grey colours and the plastic bolt heads come with or without an electrical test point.
The bolts include a section of precoat on the threads to ensure the bolt will retain the necessary torque pressure between the Cell Pillar, connector and bolt.


OPzS is used to refer to a flooded type of tubular-plate, lead acid, deep cycle batteries. These batteries, generally have a cell voltageof 2 volts and are connected in series to produce higher voltages.
These types of batteries are generally vented and are used in stationary applications like; solar, wind and backup energy storage. They contain a liquid electrolyte which is generally composed of diluted sulfuric acid.
OPzS stands for : O = Ortsfest (stationary) Pz = PanZerplatte (tubular plate) S = Flüssig (flooded)
OPzS batteries are often time referred to as stationary batteries. A variant of these types of batteries that are valve regulated and have gel electrolyte are called OPzV. These are a maintenance free variant of OPzS.
Your benefits with OPzV
Maintenance-free regarding water refilling – due to innovative Gel-technology
Very high expected service life – due to optimized lead-calcium alloy
Very high cycle stability – due to tubular plate design
Maximum compatibility – Dimensions according to DIN 40742
Optimal space utilization – due to possibility of horizontal arrangement. Higher short-circuit safety even during the installation – based on system connectors

Product Specification

Material:- Lead Alloy of 4.5% antimony for OPzS and 2T alloy for OPzV.

Electrical Vehicle Battery Connectors

With the increasing demand for electric and hybrid cars MSS has worked with its customers and supply chain partners to produce new busbars and connectors specifically designed for the electrical vehicle (EV) market.
These connectors are produced in complex three-dimensional shapes and have a variety of finishes with tin plating and insulation sleeving.

These busbars are designed to connect the EV Battery to the main electrical transmission system in the EV.
