A custom battery is only as good as the support behind it, and SUNHE ENERGY has upgraded its service to cover the entire product lifecycle.

Pre-Sales: Choosing the Right Cell Together

Before any quotation, our engineers help the customer clarify capacity, size, discharge and safety needs. We explain trade-offs between energy density, cycle life and thickness in plain terms, often flagging early where a thinner cell would reduce runtime or where a higher capacity target would raise cost, so the chosen solution matches the real product rather than a generic catalog spec.

Sample and Pilot Support

During sampling, we share test data, discuss field feedback and quickly adjust design or process. The pilot run is treated jointly with the customer, with clear acceptance criteria and fast response to any issue discovered on the bench, so surprises are resolved before volume orders begin.

After-Sales and Warranty Commitment

After mass production, we keep a direct channel for quality questions, technical adaptation and future version upgrades. Batch traceability, response timelines and a structured warranty process mean customers are never left solving a battery problem alone.
