High-Discharge Lithium Battery Pack | OEM & Custom Industrial Power Solutions
The High-Discharge Lithium Battery Pack series delivers high continuous and pulse current output for industrial machinery, mobile robotics, and heavy-duty equipment. Built with high-drain LiFePO4 or NMC cells, these packs maintain stable voltage under heavy loads while managing thermal output. Engineered for direct integration into OEM hardware, each pack is configured to precise voltage, capacity, and physical dimension requirements.
Key Features
High C-Rate Performance: Supports continuous discharge rates from 3C to 10C and high pulse currents, minimizing voltage sag under heavy motor startup loads.
Integrated BMS Protection: Real-time monitoring of cell voltage, pack temperature, and current. Includes hardware-level over-current, short-circuit, over-charge, and deep-discharge protection.
Cycle Life & Stability: Delivers >= 3,000 cycles at 80% Depth of Discharge (DoD) under 1C charge/discharge conditions (LiFePO4 variants).
Thermal Management: Integrated aluminum cooling plates and thermal conductive silicone pads designed to dissipate heat during high-rate operation.
Communication Protocols: Standardized data transmission via CAN 2.0B, RS485, or SMBus for real-time telemetry integration with host controllers.

FAQ
Q: What is the maximum continuous discharge current this pack can sustain?
A: Standard configurations support up to 200A continuous discharge. Exact limits depend on thermal dissipation parameters, terminal connector ratings, and wire gauge selected in the custom design.
Q: Can the BMS communicate with our host PLC or microcontroller?
A: Yes. The onboard BMS supports standard CAN 2.0B and RS485 protocols. Register maps and communication protocol documents are provided for software integration.
Q: What is the lead time for custom battery pack samples?
A: Standard prototype development and electrical validation take 15 to 25 business days following drawing sign-off and specification confirmation.
Q: How do you ensure cell balancing during operation?
A: The BMS utilizes active or passive cell balancing algorithms (triggered at >= 3.40V for LiFePO4) to maintain uniform cell voltages and prevent premature capacity degradation.
Q: Are your battery packs certified for international transport?
A: Yes. All designs undergo UN38.3 laboratory testing. Full compliance documentation is issued for every production batch to clear customs and freight inspections.
Q: What data is required to start a custom battery project?
A: Provide continuous and peak operating current, working voltage range, dimensional envelope (CAD files preferred), operating temperature range, and target application run time.
