A good quote starts with a good spec — CMX Battery returns an engineering proposal with test data and a certification path within three working days of your RFQ.
Overview
To quote fast and accurately, CMX Battery needs the essentials: the product type (cells, module, residential/C&I system, portable, custom pack), voltage and capacity, physical envelope, peak and continuous current, target certification and annual volume. The more precise the spec, the closer the first proposal lands. We respond with a design or matched SKU, per-cell test data where relevant, a certification path for your market, and lead time and MOQ scaled to volume. For private label or custom work we sign an NDA before detailed development. Use the form below, or email sales@cmxbattery.com with your spec sheet.
Key specifications
| Specification | Value | Why it matters |
|---|---|---|
| Need | Product type + voltage + capacity | Core spec. |
| Envelope | Dimensions, duty, IP | Stationary/mobile/marine. |
| Current | Peak + continuous | Sets BMS and C-rate. |
| Certs | Target market standards | UN38.3 minimum. |
| Volume | Annual quantity | Lead time and MOQ. |
Typical applications
- Distributors: Container RFQ.
- Installers / EPC: System RFQ.
- OEM brands: Custom/private-label RFQ.
- Importers: Certified supply RFQ.
How to specify & buying guide
- Send product type, voltage, capacity, envelope, current, certification and volume — completeness speeds the proposal.
- Expect per-cell test data and a certification path, not just a price.
- For custom/private-label, an NDA comes before detailed design.
- Reference the product Silo pages if you are not sure which product fits.
