Description
The EvoLife Lithium12.8V 7Ah Lithium Iron Phosphate(LiFePO4) battery. With basic maintenance and care this battery will give you many years of trouble-free service. The 12V 7Ah Lithium-Ion Battery makes for a great replacement solution for any devices or machines that are typically powered by lead batteries such as gate motors, alarm systems, electric fences, & CCTV systems. With its ultra-safe battery management system, this Lithium-Ion Phosphate (LiFePO4) battery lasts up to 10x longer than a typical lead acid battery and can also handle higher currents. It also does not produce fumes nor does it leak, allowing you to mount the battery in any position.
Battery Management System (BMS) Features
All EvoCharge Batteries come with a built-in Battery Management System (BMS) that protects the cells for long-term cycling. The BMS protects against the following conditions:
High Voltage: > 14.6V
If an individual cell voltage exceeds a prescribed threshold during charging, the BMS will prevent a charge current from continuing. Discharge is always allowed under this condition.
Low Voltage: < 10V
If an individual cell falls below a prescribed threshold during discharge, the BMS will prevent further discharge. Although the battery is in “low-voltage disconnect” mode, it will still allow a charging current. (Note: many chargers must detect a voltage over 10v to send a charge to the battery).
High Temperature: > 57°c
The BMS will not allow a charging or discharging current. 1. Only use a 14.6V charger suitable for 12V Lithium Iron Phosphate (LiFePO4) batteries. as well as the battery and make sure to connect correctly. NEVER REVERSE CONNECT!! 4. Speak to us about our range of EvoLife chargers. 2. The charge current must not exceed 7A. 3. Before connecting the charger, confirm the positive and negative terminals of the charger Storage: simply charge the batteries to at least 50% state-of-charge and disconnect from any charge or load. After charging disconnect the charger from the AC supply. 12.8V 7Ah LiFePO4 BATTERY Model No: ECL-12-007 www.evocharge.co.za Battery Management System (BMS) Features
Low Temperature: < -4°C
The BMS will not allow a charging current.
High Current
The BMS will not allow a current that exceeds 7(+/-5%) Amps for 30s, or 14 (+/-10%) Amps for 5s. Although these thresholds have been verified with a DC load bank, the 30-second high current threshold may be reduced from 14A to around 7A for certain highly variable loads through an inverter–like a microwave or space heater. After a high current disconnection, the battery will automatically reconnect after 5 seconds. A passive balancing process is activated by the BMS at the top of each charge cycle when the battery voltage exceeds around 13.6V. This ensures that all the cells remain at the same state of charge, which helps for pack longevity and performance.
