Product Details
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.
Company Profile
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 FairylandSolarTM 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 CASISOLARTM 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.
