Description

The TDT BMS LFP 20S 100A Same Port is a Battery Management System designed for 20-series LiFePO4 battery pack configurations. It supports a specified current rating of 100A and features a same-port connection design for charging and discharging. This model is intended for battery assemblies using lithium iron phosphate cells connected in twenty series groups. It is sold under the SUPERWAY brand through Superway.

A 20S LiFePO4 battery pack consists of twenty cell groups connected in series. With a typical nominal voltage of approximately 3.2V per cell group, a 20S configuration has a nominal pack voltage of approximately 64V. The actual voltage varies according to the battery’s state of charge and operating conditions. The battery cells, charger and BMS must all be suitable for the same chemistry and series configuration.

The specified current rating of this model is 100A. When selecting a BMS, compare this rating with the current requirements of the connected equipment and battery cells. The continuous and peak current capabilities should be confirmed using the product datasheet or supplier specifications. The battery cells, connecting wires, terminals and connectors must also be suitable for the intended load.

This model features a same-port design, meaning the charging and discharging connections use a shared port arrangement. This connection type can be relevant when planning the battery pack wiring and selecting compatible charging and load connections. Always refer to the manufacturer’s wiring diagram to identify the correct terminals, polarity and connection sequence before installation.

The TDT BMS LFP 20S 100A Same Port is intended specifically for LiFePO4 battery chemistry. LiFePO4 cells have different voltage and charging characteristics from NMC and other lithium battery types. Using a BMS designed for the wrong chemistry or series count can result in incorrect battery management. Therefore, this model should be used only with a suitable 20S LiFePO4 battery configuration.

The charging system must be selected according to the specifications of the LiFePO4 cells and the complete battery pack. Charging voltage and current should follow the cell manufacturer’s recommendations. A charger intended for another battery chemistry or series configuration should not be used unless the manufacturer confirms that it is suitable.

A Battery Management System is an important part of a battery assembly. Its circuit design determines how the battery pack is managed during charging and discharging. However, specific protection functions and additional features of this model should be verified through the actual product datasheet. Details such as overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, temperature monitoring and balancing are not assumed here. Any balancing method or balancing current should also be confirmed separately.

Correct installation is essential for the intended operation of the BMS. Before connecting the unit, verify that the battery contains twenty series-connected LiFePO4 cell groups. Follow the manufacturer’s wiring instructions for the cell-sensing connections and main power terminals. Check the connection order, polarity and terminal arrangement carefully before connecting the charger or load. Incorrect wiring can damage the BMS or battery pack.

The TDT BMS LFP 20S 100A Same Port can be considered for LiFePO4 battery pack projects requiring a 20S configuration, a specified 100A current rating and a shared charging and discharging port arrangement. Before selecting the model, check the battery pack voltage, expected load, charging requirements, physical dimensions and wiring arrangement. The BMS rating should be appropriate for the complete battery system, not just the connected equipment.

Choosing the correct BMS involves matching the battery chemistry, series count, current requirements and connection design. The charger, battery cells, cables and connectors should also meet the required electrical specifications. Following the manufacturer’s installation instructions and checking all connections before operation are important steps when assembling a battery pack.

The TDT BMS LFP 20S 100A Same Port is available under the SUPERWAY brand through Superway. Review the product specifications and wiring details before purchase to confirm that this model matches your 20S LiFePO4 battery pack requirements.
