Voltage equalization and regulation device with a robust plastic housing - Durable plastic housing: the shell is built from plastic to provide robustness and long service life for the voltage equalization system. - Battery equalizer: activates automatically when the voltage difference between two blocks reaches 10 mV; designed for reliable, long-lasting operation. - Voltage regulator: compatible with most battery chemistries, including nickel-based and lithium iron phosphate (LiFePO4) batteries; acts as a voltage stabilizer. - Battery bank protection: plastic construction offers practical protection for battery banks and uses in demanding environments. Use scenarios - Off-grid solar power systems: balance two battery blocks in a small solar storage array to improve longevity and performance. - Backup power systems and UPS: maintain voltage balance across cells in Ni-based or LiFePO4 packs for stable operation. - DIY portable battery banks: protect and balance stacks for tools or field applications, enhancing reliability and battery life.
