4.2V 2500mAh BP-4L Li-Ion Battery
Designed with "professional-level battery life + full compatibility" at its core, this BP-4L Li-ion battery is tailor-made for devices with a rated voltage of 4.2V. It effortlessly solves pain points like insufficient device battery life and performance degradation of old batteries, making it an ideal replacement/backup battery choice for photography professionals and daily users alike.

Core Specifications for Uncompromised Performance

Crafted with high-quality Li-Ion Batteries, this battery features a rated voltage of 4.2V and a nominal capacity of 2500mAh, combining high energy density with stable high power output. Compared to ordinary low-capacity batteries, it delivers longer-lasting non-stop power supply for your devices. For instance, when paired with 96/112 LED camera video lights, it supports hours of uninterrupted shooting—preventing workflow disruptions due to battery drain during outdoor or high-intensity work. Additionally, it boasts the advantage of no memory effect, allowing you to recharge it without full discharge. Even after multiple charge-discharge cycles, it maintains stable capacity.

Multiple Safety Protections for Worry-Free Use

Safety is the core bottom line of any battery. This BP-4L battery is built with four-layer safety protection mechanisms: precise over-charging protection (prevents device damage from excessive voltage), intelligent over-discharging protection (automatically cuts off power at low battery to protect batteries), short-circuit protection (quickly powers off in case of circuit abnormalities), high-temperature protection (operates stably in high-temperature environments). Moreover, the battery complies with international safety certification standards (such as CE and FCC certifications) and undergoes multiple rounds of testing—including charge-discharge cycle, drop, and squeeze tests—during production.
