BOSCH 4A & YAMAHA Charger: Factory Supply Chain Display

First of all, let's make a simple self-introduction: we are not the kind of traders who only sell ready-made products to you. We are a solid charger supplier for R&D and manufacturing.

We use professional engineering and reliable materials to provide customers with stable, safe, and time-tested products. Recently, many overseas brands and dealers have frequently asked about our several popular products. Today, I'll show you our products and take you on a visit to our production line.

BOSCH Series Charger

BOSCH's charger uses a 3Pin interface, with an output specification of 42V 4A, which can provide stable and efficient fast-charging support for BOSCH's 36V lithium battery. It is compatible with BOSCH's 36V battery system, and the 4A large current output can realize fast charging, while ensuring the stability and reliability of the charging process to meet high-intensity use needs. Whether you need a dedicated 36V battery charger or a reliable charger for electric bike, this model delivers consistent performance with excellent charger power.

YAMAHA Series Charger

Many customers in the YAMAHA ebike or after-sales market are looking for reliable battery chargers. We specially opened a set of molds for this, and launched three high-capacity lithium batteries suitable for the YAMAHA system: Yamaha 500Wh, 625Wh, and 630Wh.

We all use Grade-A power lithium batteries from major domestic manufacturers, and the cell matching and grouping process is extremely strict. Internal resistance and voltage consistency must pass our own internal control standards. Each battery is equipped with an intelligent BMS, including overcharge, overdischarge, overcurrent, short circuit, and temperature protection. It is a perfect match with the original YAMAHA charger—plug and play. As a trusted supplier of lithium battery products, we ensure that whether you choose lithium battery batteries in 500Wh, 625Wh, or 630Wh configurations, each one meets our high standards.

No matter which one you choose, we give you the same commitment: we do a thorough safety test and aging test before leaving the factory, and we do not leave problems to our customers.

Good products start from a reliable factory.

Engineering Team: Our core engineers have many years of experience in lithium battery charging development—from schematic diagram to PCB layout, from BMS software to structural design, everything is completed independently and never outsourced.

Production Line & Testing: SMT placement, post-welding assembly, battery spot-welding and capacity grading, and complete-unit aging—all are managed in dedicated zones. We have constant-temperature-and-humidity test cabinets, multi-channel capacity grading cabinets, and vibration/drop test benches. Before each product leaves the factory, it goes through a full inspection process covering "overcharge protection, short circuit protection, high-temperature high-humidity charged aging," and more.

Flexible Cooperation: Whether you want to directly take our existing standard products for private labeling, or need a custom shell solution according to your design, we can accommodate you. We offer small-batch trial orders, rapid prototyping, and customized colors and labels. As a reliable oem charger partner, we are ready to support your specific branding and customization needs.

If you are looking for a charger compatible with the BOSCH system and YAMAHA system, please contact us directly. Sample orders, technical drawing communication, and factory site visits can be arranged at any time.
