LiFePO4 Battery Modules

A battery module is where matched LiFePO4 cells become a working, protected building block — CMX Battery pairs graded cells with a purpose-built BMS, busbars and enclosure so your system integrates as wiring, not a research project.

Overview

CMX Battery modules are the bridge between loose cells and a finished system. We take matched LiFePO4 cells, arrange them for the target voltage — 12V, 24V or 48V (51.2V) — and integrate a BMS, busbars, fuses and a mechanical enclosure rated for the duty. Stationary modules are built for rack and wall mounting; mobile modules for vibration and depth of discharge. Every module is validated on capacity, internal-resistance balance and thermal behaviour before it ships, so series/parallel stacking into a cabinet stays predictable.

Key specifications

Specification	Value	Why it matters
Voltage platforms	12.8V / 25.6V / 51.2V (4/8/16 cells in series)	Standard blocks that pair with 12V, 24V and 48V inverters.
BMS	Integrated, with balancing, protection and comms	Protects over/under-voltage, over-current, over-temp; CAN/RS485 on request.
Enclosure	Metal or ABS, IP rating per duty	IP65 for indoor/outdoor stationary; sealed for mobile.
Capacity	100Ah typical; other capacities on request	Modular so you parallel for the kWh you need.
Balancing	Passive standard; active on request	Keeps series strings level over life.

Typical applications

Residential 48V banks: 51.2V modules stacked to 10–30 kWh.
RV and marine 12V/24V: Drop-in replacements for lead-acid.
C&I racks: Parallel groups in a cabinet.
OEM equipment: Custom-voltage modules built to spec.

How to specify & buying guide

Pick the voltage your inverter expects (12.8 / 25.6 / 51.2V) so the BMS and charger ranges line up.
Specify the BMS communication (none / CAN / RS485 / Bluetooth) if your system monitors the pack.
For outdoor or mobile use, set the IP rating and vibration rating before we design the enclosure.
Parallel only identical modules (same Ah, same firmware) to avoid chronic imbalance.

Engineering & manufacturing at CMX Battery

Our modules pair matched LiFePO4 cells with a purpose-built BMS, busbars and mechanical enclosure. We design for the thermal and vibration profile of the application — stationary rack, wall mount or mobile pack — and validate the assembly on capacity, IR balance and thermal runaway margin before it ships.

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.
CE — EU declaration of conformity for the applicable directives.
RoHS — Restriction of hazardous substances in the battery and BMS.
IP65 — Dust-tight and low-pressure water-jet resistant — suitable for outdoor enclosures.

Frequently asked questions

What is inside a module?

Matched LiFePO4 cells, a BMS, busbars/fuses and a mechanical enclosure — a protected, tested building block.

Can I parallel modules to get more capacity?

Yes, parallel identical modules (same voltage, Ah and BMS firmware) to scale kWh.

Do modules include the inverter?

No — modules are the battery; inverters are a separate product line we match to the pack.

Can you build a non-standard voltage?

Yes, ODM modules at custom series/parallel counts are a core service.
