Lightweight Yet Powerful Battery Design
Weighing approximately 29.6 kilograms, the Power Lithium 12V 220Ah Battery delivers roughly 40% of the weight of a comparable lead acid battery, making it an excellent drop-in replacement where weight is a concern. Despite its lighter construction, it offers twice the power and maintains a robust energy capacity thanks to its advanced lithium iron phosphate cells configured in a 4S35P arrangement.
This design also enables it to handle high discharge rates, supporting continuous current draws up to 150 amps and short pulses of up to 600 amps for demanding startup loads.
Superior Longevity and Efficiency
The battery boasts a cycle life exceeding 2000 full discharge cycles at 100% depth of discharge. This vastly outperforms typical lead acid batteries, reducing replacement frequency and minimising total cost of ownership over time.
Its low internal resistance (≤20 mΩ) contributes to high charge and discharge efficiencies, around 100% and 96–99% respectively, ensuring more of your stored energy is useable.
Self-discharge is minimal at under 3% per month, making it suitable for seasonal use or infrequent operation while maintaining charge.
Flexible Modular Configuration
Whether your power setup requires higher voltage or increased capacity, the battery’s modular design supports connecting up to four batteries in series and up to ten in parallel. This allows you to custom-tailor your power bank for electric vehicles, solar storage or backup systems, with ease of expansion over time.
Optional communication protocols such as SMBus, RS485 or RS232 are available to integrate with battery management systems, while state-of-charge indication is provided via an integrated LED.
Safe Operation Across Harsh Environments
With a wide operating temperature range from -20°C to 60°C for discharge and 0°C to 45°C for charging, this battery suits a variety of climates and applications. Its IP56 rating offers reliable protection against dust intrusion and water spray, ideal for outdoor or mobile use in variable weather conditions.
The lithium iron phosphate chemistry enhances safety by eliminating combustion risk from high impact, short circuit or overcharge scenarios common in other lithium types.
Charging and Discharging Guidelines
The recommended charging method follows a CC/CV pattern, charging to 14.6 ± 0.2 volts with a maximum charge current of 120 amps, though a typical charger current is around 60 amps. The battery should be charged within 0°C to 45°C for peak performance and longevity.
Discharge cut-off voltage is set at 8 volts to protect the battery from over-discharge, which can damage cell integrity.
To ensure best results and battery longevity, confirm that your charger and control equipment are configured for lithium iron phosphate chemistry, especially if upgrading from lead acid batteries.
Applications and Compatibility
This battery is ideal for a wide range of uses, including electric vehicles and electric mobility devices, solar and wind power storage systems, UPS and backup power supplies, telecommunication infrastructure, medical equipment, and specialised lighting solutions.
It offers a drop-in replacement for many lead acid battery setups in 12V systems but always verify physical dimensions and terminal configurations before installation, especially in confined battery bays.
