battery charger manufacturer Customized OEM battery chargers and switching power supply manufacturers – Provide personalized power solutions for lead-acid, lithium-ion, and lithium iron phosphate batteries | Power range: 20W to 5kW
Introduction
Not all battery charging and power supply requirements are uniform. As a professional OEM/ODM power manufacturer with 10 years of R&D and manufacturing experience, we not only provide high-quality universal chargers, but also focus on customizing exclusive charging and power solutions based on your battery chemistry system, voltage platform, structural size, and application scenarios. At the same time, we support flexible cooperation models ranging from single-unit retail purchase to bulk wholesale, to meet the needs of customers of different scales.

Our core capabilities
1. Customized charging and power solutions
Voltage and current customization – output covers 12V to 96V, current 2A to 200A, precisely matching the charging requirements of various lead-acid, lithium-ion, and lithium-iron phosphate battery packs.

Mechanical structure customization – including PCB layout, shell design, connector selection, installation holes, etc., completely designed and developed based on your CAD drawings or structural requirements.

Communication protocol customization – supports CAN bus, RS485, Modbus, Bluetooth, Wi-Fi, etc. standards, or can develop proprietary communication protocols to achieve seamless connection with your BMS or host system.

Charging algorithm customization – can flexibly configure multi-stage constant current constant voltage (CC/CV), pulse charging,涓流 maintenance， rapid charging and other algorithms， deeply optimizing for different battery chemical characteristics to maximize battery life and safety.

Brand visual customization – laser engraving or silk-screening your logo on the shell， and all visual materials such as packaging boxes， instructions， labels， etc.， can be made according to your brand specifications， allowing the product to fully present your brand image.

2. Switching power supply design capability (new)
In addition to battery chargers， we have complete R&D and manufacturing capabilities for switching power supplies (SMPS)， and can provide you with integrated power solutions：

AC-DC switching power supplies – cover power ranges from 20W to 5kW， suitable for industrial equipment， communication base stations， LED lighting， medical instruments， automation control， etc.

DC-DC converters – wide voltage input range， high efficiency conversion (typical value ≥ 92%)， supports boost， buck， and isolated/non-isolated topologies.

Rail-mounted power supplies – standard DIN rail installation design， specially designed for industrial control cabinets and automation systems， reliable and stable.

Customized power supply parameters – output voltage， current， ripple， hold time， protection functions， etc.， can be adjusted as needed to meet your special application requirements.
