Life
Description of Energy Storage Lithium Battery 48volt 50ah
The communication equipment required by telecom operators tends to
be integrated, miniaturized and lightweight. That is, more service
equipment can be installed in a limited space. Higher requirements
are put forward for their use of temperature range, specific
energy, and lifetime. In recent years, telecom operators and
network equipment suppliers are gradually or have begun to seek and
research new power backup solutions.

Product Features
- Product Name: Energy Storage Lithium Battery
- Energy Storage Lithium Battery cathode is made of lithium iron
phosphate (LiFePO4) material, with good safety performance and long
cycle life.
- Energy Storage Lithium Battery system adopts high-performance
special BMS battery management module, which is equipped with
voltage, current, temperature and other protection functions, and
uses the system to communicate well with the host.
- Secondary power down function, with alarm information when the
battery voltage is lower than the alarm value, and automatic power
down when the voltage is too low to protect the battery.
- Good electromagnetic compatibility of the system.
Main Advantages
- Product Name: Energy Storage Lithium Battery
- Realized that Energy Storage Lithium Battery can work directly
under the condition that the charging and discharging working mode
of the original communication DC switching power supply system
remains unchanged.
- To meet the new requirements of telecom operators for distributed
power supply systems, CASI proposes a solution based on the
integrated backup power supply of LiFePO4, BMS and DC switching
power module (or UPS uninterruptible power supply system).
Application
- Mountain communication base station
- Communication base station energy storage
- Backup power
- Outdoor Microstation
Production Process
- Li-ion battery cell sorting cabinet: all incoming cells are
subjected to secondary sorting to ensure the full capacity of the
battery.
- Sorting pairing: each cell is sorted to ensure the consistency of
the voltage and internal resistance of the cells in the same
battery pack, which effectively improves the stability of the
battery.
- Automatic spot welding: Use automatic spot welding machine to spot
weld the positive and negative electrodes of the battery pack,
which is efficient and stable without desoldering.
- Welding BMS: Welding and installing BMS for each battery pack,
which can protect the overcharge, overdischarge, overcurrent and
overvoltage.
- Finished product testing: The finished battery finally needs to go
through a number of tests to confirm that the performance is stable
and meets the standards before it is packaged and shipped.
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.
