48V Sweeper Battery Comparison: 105Ah, 150Ah, 168Ah and 230Ah
What the four 48 V classes actually store Nameplate “48 V” on a lithium sweeper pack is a system class, not the cell-string voltage. Production LiFePO₄ strings for this class are 16S. Nominal voltage is 51.2 V. Charge cutoff is 58.4 V. Discharge cutoff sits near 40–43.2 V, depending on the BMS sheet. Energy is voltage × amp-hours: Class Stored energy Usable at 80% DoD 105 Ah 51.2 V × 105 Ah = 5,376 Wh ≈ 5.38 kWh ≈ 4.30
Custom Marine Lithium Battery Systems for Electric Propulsion
A propulsion pack is not a house brick with a larger label. The motor already has a voltage, a continuous current and a charger handshake. The hull already has a locker shape, a flood line and a dock window. Custom Marine Lithium Battery Systems for Electric Propulsion exist because those four constraints rarely match a catalogue 12.8 V module. This is an architecture brief for yards, OEMs and owners who need a pack built around the motor, not a motor
What is BDU?
What is BDU? BDU is an abbreviation for Battery Disconnect Unit or Battery Distribution Unit. PDU (Power Distribution Unit): Responsible for the distribution, management, and safety protection of the vehicle’s high-voltage electrical energy. It distributes the high-voltage DC power from the high-voltage battery to key components such as the motor controller, on-board charger (OBC), air conditioning compressor, PTC heater, and DC/DC controller. From another perspective, a BDU placed outside the battery pack can be called a PDU, while one placed
