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.

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.
