Description

Traditional solar street light uses lead acid battery which has a very short life cycle and is difficult to maintain. It creates massive environmental pollution and has a very low ROI. Lithium-ion batteries we use have 3 times the life cycle and 4 times the discharge of lead-acid batteries, and it isn’t harmful for environment.
Lithium ion batteries need a proper BMS(battery management system) to avoid barrel effect. We use our own patent BMS, extend battery life span to over 6 years, improve greatly ROI, and improve energy efficiency.
When the optional extreme low temperature protection device is installed, it can work at -20℃, it is suitable for alpine regions.
