DALY SMART BMS LFP 19S 80A

DALY SMART BMS LFP 19S 80A

The DALY SMART BMS LFP 19S 80A is a smart battery management system for compatible 19-series LiFePO4 battery packs. Nineteen nominal 3.2V LFP cell groups create a 60.8V nominal pack class, commonly used in higher-voltage energy-storage and electric-mobility systems. ARB's current 19S 80A Smart CAN listing identifies an 80A continuous discharge rating, 40A charge current, common-port architecture and balancing, making the product suitable for pack builders who need both battery protection and smart communication in a high-series LFP design.

The BMS supervises the cell groups and controls the charge/discharge path according to its programmed protection limits. ARB's current listing identifies 3.8V over-voltage protection, a 69.35V charge-voltage value, short-circuit protection with recovery and temperature protection. Those values should be tied to this exact stocked model rather than copied to other DALY 19S products. DALY's wider smart-BMS ecosystem supports interfaces such as CAN, RS485, UART, Bluetooth and accessories, but the exact 19S 80A package should only promise the interfaces physically present or included. CAN compatibility also does not guarantee that every inverter or controller uses the same CAN protocol.

Use this BMS only with a 19S LiFePO4 pack and a system whose continuous and peak current demand fit the verified BMS limits. Confirm the exact CAN protocol required by the inverter, vehicle controller or display before ordering. If Bluetooth, RS485, UART or other accessories are required, verify whether they are included or optional. The cells, busbars, main cables, fuse, contactors/connectors and thermal path must all support the intended current; an 80A BMS cannot compensate for undersized pack hardware.

Applications

1. 19S LiFePO4 energy-storage batteries

2. Solar and inverter battery systems

3. Electric mobility battery packs

4. Industrial lithium battery systems

5. Backup-power and UPS battery projects

6. Smart battery packs requiring CAN communication

Installation Guide

Follow the DALY wiring sequence for the balance harness and main current terminals. Verify all nineteen cell-group voltages before connecting the BMS. Use the specified common-port arrangement and correctly sized conductors. Keep NTC sensors in the intended thermal locations and route communication wiring away from high-current cables where practical. Before full-load use, commission the pack at lower current, check app/host readings, verify CAN communication and monitor temperatures at the BMS, cable lugs and busbars.

Why Choose ARB Accessories?

ARB Accessories focuses on lithium-battery, EV, energy-storage and battery-pack assembly components. The catalog brings together BMS boards, connectors, insulation materials, battery boxes, wiring, cell interconnect materials, testing equipment and assembly tools. For battery builders, repair workshops and OEM buyers, sourcing related components from one specialist catalog can make specification matching and procurement easier. Final suitability should still be checked against the exact battery design, equipment model and electrical requirements before installation.
