9-36V 8S-32S Battery Management System with Dual Isolated CAN Bus
DTH2413 BMS board — 215 × 100 × 26 mm, 9–36V platform, 8S–32S configuration.
Product Summary
The DTH2413 is a battery management system built for mini electric vehicles, low-speed four-wheelers, sightseeing vehicles and energy storage systems. It runs on a 9–36V voltage platform with 8S–32S cell configuration and supports both 12V and 24V power supplies. NCM, LMO, LCO and LFP chemistries are supported, current detection spans -500A to 500A, and communication is handled by two isolated CAN channels plus one RS485 port. Five-channel total voltage detection covers 0–150V at ±1% FSR, with eight external NTC temperature channels and a -30°C to 85°C operating range.

Key Features
- Wide 9–36V platform with 8S–32S cell configuration — one board can be specified across 12V and 24V mini-vehicle and storage builds, reducing the number of BMS part numbers a project has to carry.
- Dual isolated CAN plus RS485 — isolated links keep communication stable in electrically noisy vehicle and cabinet environments and connect directly to a VCU, charger, display or IoT gateway.
- Five-channel total voltage detection, 0–150V at ±1% FSR — pack-level voltage is measured accurately for reliable protection thresholds and state estimation.
- -500A to 500A current detection with Hall or shunt input — covers both small packs and high-current discharge events, with system self-check for validation during commissioning.
- SOC error ≤5% and SOH accuracy ≤8% — gives operators trustworthy range and remaining-life data for fleet dispatch and service planning.
- Six-channel high-side relay output at 1A continuous / 5A instantaneous, with pre-charge — controls contactors and pre-charge paths directly, and 50mA passive balancing keeps series cells aligned.

Models and Options
The DTH2413 is offered across the 9–36V platform with 8S–32S cell configuration, so a single model family can be ordered for different series counts and pack currents. Selected models can connect with an APP, PC, IoT platform or display to support vehicle monitoring and later software expansion.
Pengpai Energy's published BMS line-up also includes the B2107, DTH2411, DTH2302, DTH2410 and B2003 series. Specifications for those models are available on request and can be matched to your pack voltage and current profile.
Materials and Structure
The DTH2413 is a compact board-level assembly measuring 215 mm × 100 mm × 26 mm. The structure combines five total-voltage detection channels, eight external NTC temperature inputs, Hall/shunt current sensing, two isolated CAN transceivers and one RS485 interface, with six high-side relay drivers rated 1A continuous and 5A instantaneous. ACC, A+ and CHG_IGN wake-up inputs are provided for vehicle integration.
Enclosure and connector material grades are not published in the current DTH2413 specification sheet; the bill of materials for these items is confirmed with engineering against each project's requirements.
Applications
- Mini electric vehicles and low-speed four-wheelers using 12V or 24V packs
- Sightseeing vehicles operated in scenic areas and cultural tourism sites
- Energy storage systems and microgrid installations
- Industrial park and hotel & resort energy management projects
- Smart scenic area fleets requiring remote monitoring via IoT platform or display
Customization
Customized PCBA and integrated hardware-software development are available and confirmed against cell chemistry, series count, current, communication protocol and operating conditions. Because the DTH2413 already spans 8S–32S and 9–36V, most project-specific work focuses on connector layout, protocol mapping and firmware behavior rather than a new platform.
