International Brands We Collaborate With
Professional 48V Lithium Battery Charger Supplier in China
48V lithium battery chargers are used with electric two-wheelers, E-rickshaws, battery-powered equipment, and selected energy-storage systems. A nominal 48V rating alone is not enough to select a charger. Battery chemistry, series count, full-charge voltage, capacity, allowable charging current, and BMS requirements must be confirmed together. Linjia reviews these details before recommending a standard model or developing a custom battery charger.
Our catalogue covers eight current options for different battery-capacity ranges: 2A for 10-17Ah packs, 3A for 14-28Ah, 5A for 24-45Ah, 7A for 35-60Ah, 8A for 40-70Ah, 10A for 50-80Ah, 15A for 70-120Ah, and 30A for 150-250Ah. These catalogue models use a DC 54.6±0.2V output configuration. The capacity ranges are selection references; the final current must also comply with the battery manufacturer's charging limit and BMS input specification.
Input options include AC 110V, AC 220V, or AC 110-220V at 50-60Hz. Regional wall plugs, output connectors, cable length, cable rating, polarity, and pin definitions can be configured for the destination market and equipment. Housing and thermal design are selected according to output power, installation conditions, ambient temperature, dust exposure, and expected operating time.
As an OEM and ODM battery charger supplier, Linjia supports specification matching, PCB and charging-profile development, in-house housing moulding and injection, assembly, electrical testing, high-voltage insulation testing, and full-load burn-in. Labels, private model codes, logos, and branded packaging can also be matched to an approved sample.

Frequently Asked Questions About 48V Lithium Battery Chargers
What Are the Main Differences Between a 48V Lithium Battery Charger and a 48V Lead-Acid Battery Charger?
A 48V lithium battery charger and a 48V lead-acid battery charger may share the same nominal voltage label, but they use different charging voltages, charging profiles, and termination logic. Lithium packs also depend on their cell chemistry, series count, and BMS limits.
The lithium models on this page are listed with a DC 54.6±0.2V output configuration. A charger should never be selected or substituted only because both products are marked 48V.
In Which Applications Are 48V Lithium Battery Chargers Commonly Used?
48V lithium battery chargers are commonly used with electric bicycles, electric scooters, electric two-wheelers, E-rickshaws, selected small energy-storage systems, and other battery-powered equipment. The correct model depends on the actual battery rather than the equipment name alone.
Installation space, connector, cable routing, charging environment, daily charging frequency, and expected charging time should be reviewed together with the battery specification.
Can a 48V Lithium Battery Charger Be Customized for a Project or Brand?
Yes. Linjia supports OEM and ODM battery charger projects based on battery chemistry, series count, nominal voltage, full-charge voltage, capacity, charging-current limit, BMS requirements, equipment interface, operating environment, and destination market.
Customization can cover the charging current, charging profile, AC input, wall plug, output connector, polarity, pin definition, cable length and rating, housing, label, private model code, logo, and packaging.
What Current Ratings and Battery-Capacity Ranges Are Available?
The catalogue lists eight current options for this 48V lithium charger series: 2A for 10-17Ah packs, 3A for 14-28Ah, 5A for 24-45Ah, 7A for 35-60Ah, 8A for 40-70Ah, 10A for 50-80Ah, 15A for 70-120Ah, and 30A for 150-250Ah.
These ranges are model-selection references, not universal battery rules. The final current must remain within the battery manufacturer's recommended charging rate and the BMS charge-current limit.
What Charger Structures and Cooling Methods Are Available?
Lower-current chargers can use compact enclosed housings, while higher-current units require more internal space, larger heat-dissipation surfaces, suitable fan cooling or other thermal measures, and higher-rated cables and connectors.
Linjia can support standard enclosed chargers, fan-cooled or naturally cooled configurations, potted models for projects requiring greater environmental protection, and open-board or semi-finished solutions for approved local-assembly projects.
Which Lithium Battery Chemistries and Full-Charge Voltages Are Supported?
The term 48V can describe different lithium battery systems. A 13-series lithium-ion pack is commonly charged to 54.6V, while a 16-series LiFePO4 pack commonly requires 58.4V. The correct value must always come from the battery manufacturer's specification and be compatible with the BMS.
The catalogue models on this page are listed at DC 54.6±0.2V. A battery requiring 58.4V or another charging voltage needs an approved specification change.
What AC Input Configurations Are Available for Different Markets?
The catalogue provides AC 110V, AC 220V, or AC 110-220V input options at 50-60Hz. A fixed-input version may suit a controlled market, while a wide-input configuration can simplify inventory for buyers supplying several countries or regions.
What Output Connectors and Cables Can Be Matched?
Output connectors can be matched by physical sample, clear photo, dimensional drawing, or approved part number. Polarity, pin definition, keying direction, contact current capacity, cable length, and conductor rating must be checked together.
How Does the Battery Management System Affect Charger Selection?
The BMS defines important limits including maximum charging voltage, accepted charging current, overvoltage response, temperature cut-off, and sometimes wake-up or communication behaviour. If the charger current is above the BMS limit, charging may be interrupted or operate unreliably.
What Protection Functions Can Be Provided?
The 48V lithium series can be configured with overvoltage, overcurrent, short-circuit, reverse-connection, timing, and over-temperature protections according to the approved circuit solution and model. Required protections, trigger conditions, recovery behaviour, and interaction with the BMS should be confirmed before production.
How Is Batch Stability Controlled from Sample to Mass Production?
Approved electrical specifications, battery information, connector samples, polarity and pin definitions, label artwork, and packaging references are used as production-control documents. Quality procedures include incoming-material inspection, semi-finished testing, finished-product electrical testing, high-voltage insulation testing, and full-load burn-in.
How Should a 48V Lithium Battery Charger Be Used and Maintained?
Use the charger only with the approved battery chemistry, series count, voltage, BMS, connector, and polarity. Keep ventilation openings clear, avoid covering the charger during operation, and do not use damaged cables, loose connectors, or a damaged housing.
