260mm Solar Street Light Lithium Battery 45Ah Mppt Solar Charger

12V 24V Solar Street Light Lithium Battery MPPT Controller Integrated

Description of 12v 45ah lithium battery

The solar street light lithium battery has built-in advanced intelligent BMS microcomputer management system with early warning and three protection functions such as overcharge, overdischarge, overcurrent and temperature, and has good communication with PC.
At the same time, the lithium battery can carry out automatic charge and discharge management and monitoring unit to automatically measure the charge and discharge current of the battery and manage the continuous floating charge balance of the battery.

12v 45ah lithium battery Features

• low light level charging, improve the charging efficiency and charge a single group of cells evenly.
• Intelligent operation, detection of charge discharge ratio to ensure bright light in rainy day.
• Intelligent matching light source to improve load efficiency.
• Read the working status and write the working parameters in real time.
• Automatic overcharge and overdischarge activation.

Main Advantages of 12v 45ah lithium battery

• Waterproof Aluminum Alloy Shell: The solar street light lithium battery is used outside, so we have to adapt to all kinds of weather. Here we use IP67 aluminum alloy shell, which is waterproof, collision-proof and fire-proof to ensure adequate battery safety.
• Integrated Design: The controller can also be placed outside, simply leaving two cables outside, one connected to the solar panel and the other to the light, making the assembly work easier.
• Easy Installation: Groove design with screw fixing for easy installation.

Production Process of 12v 45ah lithium battery

• Capacity separation of lithium battery cells: All cells should be divided for the second time to ensure the full capacity of the battery.
• Battery pack: The internal resistance and voltage of the battery core are paired in groups to ensure that all internal resistance and voltage of the whole battery pack are consistent, and the products with higher safety and quality can be achieved
• Bracket combination: The battery pack adopts the safest bracket combination, so the heat dissipation effect of the battery pack is better and more reliable.
• Battery spot welding: Spot welding with pure nickel sheet has the advantages of small internal resistance, large over-current and no heating.
• Battery management system: Highland barley paper is used for insulation protection and safety protection when the battery is connected; The protection board has the functions of overcharge protection, over discharge protection, over-current protection and balance protection; It has no memory effect and can be charged and discharged at any time
• Aluminum alloy shell packaging: The battery pack is packed with IP67 aluminum alloy shell, which not only makes the appearance beautiful, but also makes the safety protection of the battery not to be ignored.
• Battery test: Battery aging test, charge discharge cycle test, we guarantee to do the best quality to customers.

Together with our customers and suppliers, we have been partners in solar battery industry for 12 years and have supplied over 20 kinds of patent solar systems for home and abroad.

In 2008, we established FairylandSolar^TM and won our first solar home system project--“GoldSun” project for whole Shaanxi province which was a famous big project appointed by Chinese government. During 3 years installation, we were always moved a lot when people showed true smile when lighting their home. They should carry a heavy battery and walk hours home, so aftersales is so difficult that pushes us to supply high quality products with long lifetime. We invested gel battery production line with a 50 staff team who has 20 years production experience for AGM battery. For the enough good quality and reasonable price, we becomes a stable supplier for solar projects, OEM for them.

In 2018, as the rapid development of lithium battery, we established CASISOLAR^TM that started a team only for packing lithium batteries. During the past 3years, we found the wide difference between price and products. As government promotes “ giving retied battery a second life” , some make a profit in troubled situation, providing retired cells for solar making great lost in a long term or even has personal safety hazard.

So in CASISOLAR, we don’t think it is 100% safe to use retired battery cells. We only accept cells at Great A with 5 years more warranty. We didn’t grow up quickly but we harvest every customer we have cooperated. We always enjoy and appreciate troubles met during every cooperation, and give great enthusiasm and confidence.

Our mission is to provide solar energy at low cost over a long lifetime.
