For the main positive and negative battery connections, the battery uses 16mm² pure copper DC cable.
Pure copper wiring provides good electrical conductivity and is suitable for carrying battery current with reduced cable resistance when properly installed.
The main cables are supplied in:
Red – Positive (+)
Black – Negative (−)
Approximately 1-foot length
The cable ends are fitted with 16mm² pure copper lugs for secure electrical connections.
Applications
The Voltpro Energy 12V 27Ah LiFePO4 Battery can be used in a wide range of low-voltage and backup applications.
Suitable Applications Include:
Solar Backup Systems
12V UPS Systems
CCTV Backup
Wi-Fi Router Backup
Networking Equipment
LED Lighting
DC Fans
Emergency Backup Systems
Portable Power Systems
Telecom & Communication Equipment
Small Electronic Systems
Custom 12V Energy Storage Projects
Backup Capacity Examples
Actual backup time depends on the load, inverter/DC converter efficiency, battery condition and operating temperature.
The battery has approximately 345.6Wh nominal energy.
Load Approx. Theoretical Runtime
50W ~6.9 Hours
100W ~3.45 Hours
150W ~2.3 Hours
200W ~1.7 Hours
300W ~1.15 Hours
400W ~0.86 Hour
*These are approximate theoretical values based on nominal battery energy. Actual usable runtime will be lower depending on BMS limits, inverter/DC conversion losses, load characteristics and battery operating conditions.
Important Note
This is an open battery assembly intended for installation into a suitable application, enclosure or battery housing. Always use a LiFePO4-compatible 12V charger/solar charge controller and ensure that the connected equipment is compatible with a 12V LiFePO4 battery.
