Deligreen 8S 24V LiFePO4 BMS wiring diagram

Exact board identity unresolved. Catalog models an 8S common-port negative-side BMS at 150 A, but the stock photo is labelled Li-ion and no matching LiFePO4 smart-BMS manual was verified. Confirm chemistry, current ratings, sensors and wiring against the actual board before installation.

Cable sizing for this example

Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.

Cable sizes depend on the connected equipment, current and cable lengths. Add those details in Crimp to size each run.

Installation notes

Before you install.

Open a question for model-specific guidance and sources.

Exact model identity remains unresolved, checked 2026-10-01. Confirm the nameplate and matching manual before using these notes for installation. Manufacturer documentation →

Has this exact BMS been identified?

No exact manufacturer model or matching installation manual was verified. This page records the identification gap so the catalog entry is not mistaken for a commissioned battery design. The review date describes that investigation, not approval of the board's ratings.

The catalog calls it an 8S 25.6 V LiFePO4 smart BMS with Bluetooth/UART. Its reference photograph instead shows a red unit labelled Li-ion 8S 24V BMS, common port, with balance, and 150 A charge/discharge markings. That stock photograph does not establish the installed board's chemistry, firmware, communication interface or continuous thermal capability.

What did the supplier evidence establish?

The linked Deligreen supplier listing describes a Daly 8S 24 V 200 A Bluetooth product. It demonstrates that Deligreen supplies named variants, but it is not a manual or specification for this catalog's 150 A placeholder. Its currents, protection thresholds and wiring details have not been copied into this entry.

A similar red enclosure, two large leads or the same seller name cannot establish that two BMS boards share their internal design. A manual for another Daly or JK model is not a substitute for the missing exact-board document.

What does the terminal map actually claim?

The catalog presently models a common-port negative-side BMS: B− is the cell-pack negative and P− the shared charger/load negative. Pack positive is outside that switched path. This is the catalog's intended topology, not independently verified connector or lead-color guidance for an unidentified board.

Do not infer cell-sense pin order, harness connection sequence or activation procedure from these two power terminals. The drawing contains no cell taps, temperature sensors, balancing connections or communications. These omissions prevent it from functioning as a pack-assembly instruction.

What must be resolved before installation?

Match the actual board label, PCB/model revision, cell chemistry and series count to supplier-issued documentation. Obtain separate charge/discharge current limits with their temperature conditions, low-temperature charge behavior, short-circuit response, balance settings, harness pinout and any required precharge procedure.

The existing modeled 150 A value is not evidence for choosing a cable or fuse. Fault protection must also be selected for the real battery and conductor independently of a BMS's claimed trip current. Until the exact board is identified, do not use another product's torque, cutoff settings or fuse recommendation to close these gaps.

Fit check

Connect it to the rest of your system.

Describe your setup to draft a system with 8S 24V smart BMS connected. Review the selected parts and cable lengths, then edit the diagram in Crimp.

The model only picks parts and draws the connections. Every wire size and fuse rating still comes from Crimp's own sizing, never from the model.
