It is designed for customers who want dependable stored energy together with an additional layer of cell balancing and battery protection.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the Battery Protector is included\u003c\/h2\u003e\n\u003cp\u003eLiFePO4 packs contain multiple cells connected in series. Over time, small differences between cell voltages can become more noticeable, particularly in batteries that are charged and discharged frequently. The matched 4S protector monitors the correct series configuration and actively discharges higher-voltage cells when balancing conditions are reached.\u003c\/p\u003e\n\u003cp\u003eThis helps keep the cells closer together in voltage, supports more consistent charging and discharging, and helps the battery use its available capacity more evenly. The protector also provides overcharge, over-discharge, over-current and short-circuit protection. It does not increase the battery's rated capacity and does not replace correct charging equipment or professional installation.\u003c\/p\u003e\n\n\u003ch2\u003ePackage contents\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × MICROMALL 12.8V 210Ah Essential LiFePO4 Battery — SKU: BTL-12.8V210\u003c\/li\u003e\n  \u003cli\u003e1 × MICROMALL 4S LiFePO4 Battery Protector — SKU: 12V-BP\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBattery performance\u003c\/h2\u003e\n\u003cp\u003eThe included 12.8V 210Ah battery provides 2.6kWh of nominal energy and approximately 2.4kWh of usable energy.
