10.8V 140Ah 1512Wh Li-ion Pack (Smart BMS)

10.8V 140Ah 1512Wh Custom Lithium Battery Pack with Smart BMS & LCD Display

Engineered for OEM applications requiring high capacity in a compact, deployable form factor, this 10.8V 140Ah lithium-ion battery pack delivers an industry-leading 1512Wh of stored energy at just 6.5kg. The pack is built around premium prismatic Li-ion cells arranged in a 3S1P configuration, with a built-in smart battery management system (BMS) and a detachable Smart Battery System LCD display module that reports real-time voltage, current, remaining capacity, and temperature over the SMD (System Management Bus) communication protocol.

Key Features

• High Energy Density: 1512Wh of usable energy in a single pack — among the highest capacity 12V-class Li-ion packs available for OEM integration.
• Smart BMS with LCD Display: Real-time monitoring of Voltage, Current, RemCap, and Temperature. SMD communication protocol (VCC / SMBC / SMBD / GND) for system-level integration and remote diagnostics.
• Wide Operating Range: Discharge from -20°C to 45°C, charge from 0°C to 45°C — built for industrial and outdoor deployments.
• Multi-Layer Protection: Over-discharge (2.5V per cell), over-current (115–125A), short circuit, and thermal protection via integrated BMS.
• Low Internal Resistance: ≤60mΩ @ 1KHz AC for high efficiency and minimal voltage sag under load.
• Long Cycle Life: Premium prismatic Li-ion cells deliver extended cycle performance for B2B applications.
• OEM-Ready Design: Customizable housing color, wiring harness, connector type, BMS firmware parameters, and label branding available for volume orders.

Detailed Specifications

Smart Battery System LCD Module

The included Smart Battery System displays four critical parameters in real time and communicates over the SMBus protocol:

• Voltage — instant pack voltage with 1mV resolution
• Current — live charge / discharge current in mA
• RemCap — remaining capacity in mAh, based on coulomb counting
• Temperature — cell temperature in °C (sampled by integrated NTC)
• PU/PD button — page up / page down between three display pages (P1, P2, P3)
• ON/OFF button — powers the LCD backlight and SMBus output

Typical Applications

• Mobile power stations and portable energy storage (PES)
• AGV / AMR robotics and warehouse automation
• Medical carts, mobility devices, and rehabilitation equipment
• Industrial backup power and small-scale UPS systems
• Solar storage and off-grid renewable energy systems
• Custom OEM projects requiring 12V-class high-capacity lithium packs
• RV / marine auxiliary power and overland builds
