48V 200Ah Power Lithium Iron Battery
Description:
This product is a new type of backup power supply for the
development of high-tech products,
with integration, miniaturization, light, intelligent,
standardized, environmental protection and other
characteristics, can be widely used in indoor distribution
stations, integrated base stations, marginal
stations, distributed power supply and other fields.
Adopted by the high safety performance, lithium battery cathode
material for lithium iron phosphate,
high safety, high stability, high cycle life, high specific energy,
specific power, low temperature performance
is superior, but large current charge and discharge, and many other
advantages, at the same time, using
suitable for communication demand special high performance battery
management system (BMS), with
the charge, over discharge, short circuit, over-current (load),
temperature, flow, total pressure protection.
Manufacturing standard:
- YDB032-2009 communication backup type lithium ion battery pack
- YDT - 2011-2344.1 the communication lithium ironphosphate battery
part 1: integrated battery
- "YDT, 1051-2010" communication board (stand) power system total
technical requirements "
- YDT - 2005-1363.3 the communication board (station) power supply,
air conditioning and environment centralized monitoring management
system "of the relevant standards.
Feature:
1. Standard design, low operating environment requirements (can be
in -20 ~ 60℃ humidity < 95%
normal work), small size, light weight, easy installation, simple
maintenance in the later stage,
can save considerable upfront investment and maintenance costs in
the later stage.
2. Automatic charge and discharge management. The monitoring unit
automatically measures the
charge and discharge current of the battery and manages the
floating charge and even charge
of the battery;
3. When the battery voltage is lower than the alarm value, it will
alarm, and when the voltage is too
low, it will automatically power down to protect the battery.

| 3 | High Temperature Performance Test | Keep the battery at a hot oven with 55±2℃ for 2 hrs, then measure
the capacity with constant discharge current 0.5C to discharge
protection point after complete charge. After the test, keep the
battery at 20±5℃ for 2 hrs. | Appearance of the battery shall not rust smoke or explode.
Discharge
Capacity >90%. |
| 4 | Low Temperature Performance Test | Keep the battery at -20±2℃ for 16-24 hrs, then measure the capacity
with constant discharge
current 0.5C to discharge protection point after
complete charge. After the test, keep the battery at
20±5℃ for 2 hrs. | Appearance of the battery shall not rust, smoke or explode.
Discharge
Capacity >55%. |
