city power is expensive, the battery pack can be charged during the electricity valley value period, and used at the peak
power period; For the areas which power off from time to time, the battery pack can be used as UPS, to avoid
information loss caused by sudden power outage. The battery pack is applicable to commercial lighting, industrial
lighting, home lighting, outdoor lighting, camping tourism, farming, planting, the night market stalls, etc.

Instructions
Attention:
It is forbidden to use any high-voltage to charge it. The open circuit voltage of 12V battery pack can not exceed
22V, 24V battery pack can not exceed 44V and 48V battery pack can not exceed 88V. The maximum open circuit
voltage of solar panel can not exceed twice of the voltage of battery.
Please use a MPPT controller with lithium iron phosphate battery mode.
The output must have high-voltage isolation function when using high-voltage MPPT controller.
When the source voltage of the charging terminal is higher than 88V, in order to prevent the failure of the voltage
conversion device in the middle and cause overcharging of the battery. The high-voltage circuit breaker with
charging protection function must be connected between the charging controller and the battery.
12V battery pack, maximum support 4 battery packs in series, the highest charging voltage of 4 battery packs in
series is less than 88V, and the highest charging voltage of 2 battery packs in series is less than 44V. 24V battery
pack, maximum support 2 battery packs in series, the highest charging voltage of 2 battery packs in series is less
than 88V. 48V battery pack, it is forbidden to use in series. Ensure the batteries are discharged to empty condition
or fully charged before connecting them in series. Ensure the voltage of batteries are consistent before connect-
ing the batteries in parallel.
It is forbidden to connect the positive and negative poles reversely and short circuit the positive and negative
poles of the battery pack; The overload is strictly prohibited.
The battery pack should not be used in severe vibration scenarios.
It is strictly prohibited to put in water and clean the battery pack, and do not place the product in the outdoor
exposed place for a long time to prevent rain or moisture.
It is forbidden to use or place the battery at high temperature. If battery is used for a long time, the recommend-
ed optimal ambient temperature is 10-40℃.
The battery should not be placed in the room where any combustible gas or flammable items are stored, and
should be used in a clean, dry and ventilated environment.
It is strictly prohibited to knock, throw, reverse or trample on the battery pack. It is strictly prohibited to use the
battery pack when the appearance is seriously damage (artificial knocking, scraping, falling from height,
unauthorized disassembly of the products, etc.).
It is strictly forbidden to dump or invert the product.

Never upside down the positive and negative.
Never connect the positive and negative of battery with metal.
Never ship or store the battery together with metal.
Never knock, throw or trample the battery.
Never cut through the battery with nail or other edge tool.
Never use or keep the battery under the high temperature. Otherwise it will cause battery heat, get
into fire or lose some function and reduce the life.
Never throw the battery into fire or heating machine to avoid fire, explosion and environmentpollution;
scrap battery should be returned to the supplier and handled by the recycle station.
Never use the battery under strong static and strong magnetic field, otherwise it will destroy the
protecting device.
If battery leaked, the electrolyte get into eyes, please don’t knead, please wash eyes by water and
send to hospital. Otherwise it will hurt eyes.
If battery emit peculiar smell, heating, distortion or appear any unconventionality duringusing,
storage or charging process, please take it out from device or charge and stop using.
Never cut the battery in socket directly; please use the stated charger when charging.
Check the voltage of battery and relevant connectors before using the battery. It can’t be used until
everything turns out to be normal.
The battery should be stored in half SOC. It needs to be charged once if out of use foras long as half a
year.
Clean the dirty electrode, if any, with a clean dry cloth, or poor contact or operation failure may occur.
Prior to charging, fully check the insulativity, physical condition and ageing status, since breakage
and ageing are never allowed.
