16mm² Pure Copper Flexible DC Cable

Product Description

The 16mm² Pure Copper Flexible DC Battery Cable is a full-gauge, high-quality DC power cable designed for reliable battery and power connections. Made with a pure copper conductor, it provides excellent conductivity, low electrical resistance and flexible handling.

Its flexible multi-strand construction makes it ideal for use with LiFePO4 batteries, solar systems, inverter batteries, UPS systems, battery cabinets and EV applications.

The 16mm² size is particularly useful for medium-to-high current battery connections where proper cable sizing, short cable runs and efficient power transfer are required.

Where Can 16mm² Cable Be Used?

🔋 12V LiFePO4 Batteries

16mm² pure copper cable can be suitable for many 12V-class LiFePO4 battery connections, particularly medium-current applications.

Examples:

12.8V 50Ah

12.8V 100Ah

12.8V 200Ah

For high-current 12V systems, cable sizing should be checked carefully because current increases significantly at lower voltage.

⚡ 24V LiFePO4 Batteries

16mm² cable is useful for many 24V battery systems, depending on the actual inverter/load current and cable length.

Examples:

25.6V 100Ah

25.6V 200Ah

25.6V 314Ah

🔋 48V / 51.2V LiFePO4 Batteries

16mm² cable can be particularly useful in many 48V/51.2V systems, because higher system voltage requires less current for the same power output.

Examples:

51.2V 100Ah

51.2V 200Ah

51.2V 314Ah

Example Power Calculation

For a 51.2V battery powering a 5kW inverter:

5000W ÷ 51.2V ≈ 98A

A 16mm² cable may be suitable for some installations at this current, but the final selection must consider cable length, insulation, temperature, installation method and permissible voltage drop.

For longer runs or higher-current applications, a larger conductor may be required.

Suitable LiFePO4 Battery Applications

16mm² cable can be used for appropriately designed:

12V 50Ah LiFePO4 Batteries

12V 100Ah LiFePO4 Batteries

12V 200Ah LiFePO4 Batteries

24V 100Ah LiFePO4 Batteries

24V 200Ah LiFePO4 Batteries

24V 314Ah LiFePO4 Batteries

48V / 51.2V 100Ah LiFePO4 Batteries

48V / 51.2V 200Ah LiFePO4 Batteries

48V / 51.2V 314Ah LiFePO4 Batteries

Note: Battery Ah capacity alone does not determine cable size. Maximum current and cable length are more important factors.

Installation Recommendations

For reliable installation:

Use correctly sized cable lugs.

Use proper crimping tools.

Install an appropriately rated DC fuse/breaker.

Keep cable runs as short as practical.

Avoid excessive bending near terminals.

Ensure terminals are properly tightened.

Prevent cable abrasion and mechanical damage.

Select the cable according to actual continuous and peak current.

16mm² vs 25mm² Battery Cable

Feature 16mm² Cable 25mm² Cable

Conductor Pure Copper Pure Copper

Cross Section 16mm² 25mm²

Flexibility Excellent Excellent

Typical Use Medium/High Current Higher Current

Cable Weight Lower Higher

Space Requirement Lower Higher

Suitable for LiFePO4 ✅ ✅

Solar Systems ✅ ✅

Inverter Systems ✅ ✅

High-Power Applications Depends on current Better suited

Simple rule: If the system requires higher current or a longer cable run, 25mm² may be preferable. For lower/medium current applications, 16mm² can be a practical choice.

Package Includes

1 × 16mm² Pure Copper Flexible DC Battery Cable

Available for suitable positive (+) and negative (−) DC battery connections.

Important Note

Do not select the cable based only on the battery's Ah rating. The correct conductor size should be determined from the maximum continuous current, peak current, cable length, system voltage, installation method and permissible voltage drop.
