SYSTEM OVERVIEW
The LiFTFORCE Lithium battery system is an enclosed tray containing GNB Lithium Battery Modules in
various capacities. The Battery Management System (BMS) and contactors are built into the tray and the
system is equipped with a Curtis Engage II gauge or Opus A3 display, which shows battery parameters
during charge and discharge.
The battery is fitted with an over discharge protection device, which will prevent the battery entering a
critical level of discharge. A buzzer is fitted to the vehicle to alert the operator of this situation.
Both the display and the buzzer need to be mounted in a convenient place on the vehicle and this should
be done in consultation with the GNB Application Engineer. The GNB Lithium battery system is completely
self-contained and can be used as a direct replacement for all current in-use Lead Acid systems.
Figure 1 below shows the cables and connectors on the top of the tray. The power leads exit the tray
through glands and are not field replaceable. A CANbus connection lead also runs with the power leads to
a REMA plug to connect with the Charger for CAN controlled charging.
A custom lead to the Curtis gauge is provided with a connector to the battery tray. This lead can be
replaced in the field. A service port has also been provided for monitoring the modules and cell blocks.
