Precautions
01 SAFETY PRECAUTION
•It is very important and necessary to read the user manual carefully before in-
stalling or using the battery. Failure to follow any of the instructions or warnings in
this document can result in electrical shock, serious injury, death, or may dam-
age the battery and the whole system.
•If the batteries are stored for a prolonged time, it is requirement that they are
charged every three to six months, and the SOC should be no less than 80%.
•The battery needs to be recharged within 12 hours, after fully discharging.
•All battery terminals must be disconnected before maintenance.
•Do not use cleaning solvents to clean the battery.
•Do not expose the battery to flammable or harsh chemicals or vapors.
•Do not paint any part of the battery; include any internal or external compo-
nents.
•Do not connect battery with PV solar wiring directly.
•Any foreign object is prohibited to be inserted into any part of the battery.
•Any warranty claims are excluded for direct or indirect damage due to items
above.
1.1 BEFORE CONNECTION
•After unpacking, please check the battery and packing list first, if the battery is
damaged or spare parts are missing, please contact us.
•Before installation, be sure to cut off the external power and make sure the bat-
tery is in the turned-off mode.
•Wiring must be correct, do not mix-connect the positive and negative cables,
and ensure no short circuit with the external device.
•It is prohibited to connect the battery with AC power directly.
•It is forbidden to connect batteries in series.
•It is forbidden to connect batteries of different manufacturers or models.
•Please ensure the electrical parameters of battery system are compatible to
inverter.
•Keep the battery away from fire or water.
01
Precautions
1.2 DURING OPERATION
•If the battery system needs to be moved or repaired, the power must be cut off
first and the battery is completely shut down.
•It is prohibited to put the batteries working with faulty or incompatible inverter.
•In case of fire, only dry powder fire extinguisher can be used, liquid fire extin-
guishers are prohibited.
•Please do not open, repair or disassemble the battery. We do not undertake
any consequences or related responsibility due to violation of safety operation
or violating of design, production and equipment safety standards.

02 INTRODUCTION TO MD48 SERIES
The MD48 series includes two products, MD48-50-2U and MD48-100-3U. They are
high-performance energy storage battery systems independently developed by
BST, which are suitable for T4 Internet Data Center and residential energy storage
and other application scenarios.
2.1 KEY FEATURES
•LiFePO4 cathode material with excellent safety and life performance.
•2.4kWh 2U height, 5.12kWh 3U height.
•19 inch module design, easy to install.
•Integrates the most advanced BMS. It can collect battery information, such as
voltage, current and temperature, and manage the battery system to extend
its service life.
•Compatible with Most Inverters.
•Up to 15 in parallel.
