Products Description
Continuous Discharge
Nominal capacity 16Ah, maximum continuous discharge current 25A, covering the continuous operation requirements of 500W–1000W motors.
Low Cycle Decay
Optional LiFePO4 or ternary lithium system, with minimal lattice changes during cycling; ternary materials possess high energy storage capacity per unit mass, achieving ≥1000 cycles under standard conditions.
Hardware Circuit-Level BMS Protection
Built-in BMS monitors individual cell voltage, current, and temperature through independent sampling circuits, triggering MOSFET cutoff to provide overcharge, over-discharge, overcurrent, short circuit, and over-temperature protection. CAN communication interface supported (optional).
Customization Options
Voltage and Capacity Combination Design
Supports 48V and other voltage platforms. Series and parallel structures can be adjusted according to power requirements to achieve different capacities and discharge current specifications.
Cell System Selection
Provides two material system options: LiFePO4 and ternary lithium, matched to vehicle weight targets and usage scenarios.
BMS Parameter Setting
Supports setting charge/discharge cutoff voltage, current limit, and communication protocol (CAN/UART), enabling interface with the vehicle control system.
Structure and Installation Interface Development
Supports development of bottom-tube, rear-mounted, and embedded housings. Housing structures and locking interfaces can be customized according to vehicle frame dimensions.
Appearance and Brand Customization
Supports customization of housing logos, label information, and shipping packaging.
Packaging & Shipping
With high quality pearl wool, UN cartons / Plywood, plastic pallet.
Standard batteries lead time: Samples: 1-7 working days, Bulk order: 25-30 days.
Shipment: by sea, by railway, etc.
FAQ
Q: What power motor is suitable for a 48V system?
A: Commonly used in 500W–1000W motor systems. The operating current is lower than a 36V platform at the same power.
Q: Does 25A continuous discharge support a 1000W motor?
A: A 1000W motor operates at approximately 20–22A in a 48V system. A 25A continuous output can cover this power range.
Q: Can it be matched with different brand controllers?
A: As long as the controller voltage platform is 48V and the current requirement is within the battery output range, it can be used.
Q: What precautions should be taken when paralleling for capacity expansion?
A: Parallel batteries must be of the same model, voltage, and BMS parameters to avoid voltage differences causing balancing current.
Q: How should it be handled for long-term storage?
A: It is recommended to maintain 40%–60% charge. Avoid high-temperature environments and prolonged storage at full charge.
