Every custom battery project at SUNHE ENERGY follows a structured path, so customers always know where their product stands and what comes next.

Step 1: Requirement Collection and Feasibility

It starts with the application, size envelope, capacity target, discharge profile, temperature range and safety expectations. Our engineers review whether a pouch, cylindrical or shaped cell fits, flag any feasibility risks early, and propose a realistic direction together with the customer.

Step 2: Solution Design

Next we select or design the cell chemistry, packaging structure, protection board and interconnect method. Drawings, mechanical dimensions and electrical parameters are agreed before hardware is built, which keeps later iterations fast and controlled.

Step 3: Samples, Validation and Pilot Run

Samples are manufactured, tested internally and shipped for customer evaluation. Any feedback is folded into a revised build. A small pilot run then confirms the design can be repeated consistently on production tooling.

Step 4: Mass Production and Delivery

Once the pilot is approved, production moves to our automated lines with in-line inspection, batch traceability and outgoing quality checks. We handle packaging, transport documents and after-sales support, so the customer receives not just cells, but a dependable supply relationship.
