Lithium Battery Products

CMX Battery designs and manufactures lithium battery products for distributors, installers, EPC contractors and OEM partners who need consistent, traceable, certifiable hardware rather than a catalogue of stock SKUs.

Overview

Our portfolio spans the full stack of a LiFePO4 energy storage system: raw Grade-A cells, matched modules with integrated BMS, complete residential and commercial cabinets, MWh-scale containerised systems, and the portable or specialty packs built for shock, dust and temperature swing. Because cell grading, pack assembly, BMS firmware and testing all happen in-house, the specification you agree on is the specification that ships. Below are the product lines we build, each with its own Silo of deeper pages.

Key specifications

Specification	Value	Why it matters
Chemistry	LiFePO4 (LFP) standard; NMC and sodium-ion on request	LFP gives the best safety and cycle-life trade-off for stationary and mobile storage; we offer other chemistries where energy density or cold performance dictates.
Voltage platforms	12V / 24V / 48V (51.2V) / high-voltage 100V+ / custom	We standardise on the voltages your inverter and application expect, so integration is a wiring job, not a redesign.
Capacity range	7Ah cells to 3.44MWh containerised systems	One supplier from a single cell to a full BESS reduces interface risk across your bill of materials.
Cycle life	2,000–8,000+ cycles at 80% DoD, 25°C	Cycle life is quoted at a defined DoD and temperature; we publish the test condition so the number is comparable.
Services	OEM, ODM, private label, custom pack design, certification support	Most export volume is custom or semi-custom; we protect your brand while keeping the engineering in-house.

Typical applications

Residential solar storage: 48V LiFePO4 batteries paired with hybrid inverters for daily cycling and backup.
Commercial and industrial peak shaving: 100 kWh–1 MWh cabinets that shave demand charges and ride through outages.
Mobility: RV, marine, golf cart, forklift: Drop-in 12V/24V packs and high-discharge specialty cells built for vibration and depth of discharge.
Telecom, UPS and off-grid backup: Long-life stationary banks with the certifications operators require.

How to specify & buying guide

Start from the load profile and duty cycle, not a product photo: daily kWh, peak kW, backup hours and target DoD decide the chemistry and capacity.
Confirm the certification path for your market early — UN38.3 for shipping, IEC62619 or UL1973 for the unit, UL9540A for the installation.
Ask for per-cell matching data (capacity, internal resistance, thickness) if you are building packs; it is the difference between a pack that balances and one that drifts.
Decide OEM vs ODM vs private label up front — it changes how much of the mechanical and firmware design we own versus you.

Engineering & manufacturing at CMX Battery

CMX Battery designs and builds lithium battery products under one quality system, with cell grading, pack assembly, BMS firmware and testing all in-house. We work from your specification and document every unit for your target market.

Certifications & compliance

UN38.3 — Mandatory lithium battery transport test (altitude, thermal, vibration, shock, external short). Required for any cross-border shipment.
IEC62619 — International safety standard for industrial Li-ion cells and batteries; expected by EU and most APAC buyers.
UL1973 — North American safety standard for stationary lithium battery systems.
UL9540A — Fire safety test method for ESS installations; often required by US authorities having jurisdiction.
IEC63056 — Safety requirements for stationary lithium battery energy storage systems.
CE — EU declaration of conformity for the applicable directives.
RoHS — Restriction of hazardous substances in the battery and BMS.
ISO9001 — Quality management system certification of our manufacturing process.

Frequently asked questions

Can you build a product that is not listed here?

Yes. Most of our export volume is custom work. Share voltage, capacity, dimensions, certification target and annual volume and our engineering team returns a proposal within three working days.

Do you sell cells only, without packs?

Both. We supply matched Grade-A cells in bulk and assemble modules and complete packs with BMS, wiring and enclosure.

Are your cells new or second-life?

All cells we sell are new production. We do not trade in recycled or second-life cells.

What documentation ships with an order?

Per-cell test reports, UN38.3, MSDS, CE/RoHS where applicable, and batch traceability keyed to serial numbers.
