CONNECTION TIPS
Conditions to connect the battery in series or in parallel:
- Be the same battery capacity (Ah);
*Be from the same battery brand; - Be newly purchased within one month.
CONNECTION METHOD
Wear rubber insulation gloves before connection.
Make sure the gloves are dry and pay attention to safety while connecting.
How to Connect Batteries in Series?
After series connection, your battery system voltage will be doubled according to the batteries’quantity, you’ve connected.
E.g.: If you connect 2 x 12V 300Ah batteries in series, the battery system will be 24V(25.6V) 300Ah.
How to Connect Batteries in Parallel?
After a parallel connection, the battery capacity will be doubled according to the battery quantity you’ve connected.
E.g.: If you connect 2 x 12V 300Ah batteries in parallel, the battery system will be 12V 600Ah.
How to Connect Batteries both in Series & Parallel?
Step 1 : Connect the batteries in parallel.
Step 2 : Connect the paralleled batteries system in series.
Step 3 :
Connect the battery system to the load.
Connect battery ① negative pole to the load negative, and positive pole to
battery ⑧ positive pole to the load.
TIPS: To connect battery ② positive pole with battery ⑦ negative pole as
steps above could achieve the same effect.
NOTE: Please don’t connect battery ① positive pole with the load positive pole. Since battery ① positive pole is in series connection with battery ②. Battery system failure may occur dueto a wrong connection.
PLEASE DO NOT CONNECT THE BATTERIES IN REVERSE ORDER.
E.g.: Connect 4 x 12V 300Ah batteries for a 24V 600Ah battery system.
Step 1 : Connect the two batteries separately in parallel for 2 x 12V 300Ah
battery systems.
Step 2 : Connect the 2 x 12V600Ah battery systems in series for a 24V 600Ah
battery system.
CHARGING TIPS
*About Charging Voltage
Based on the characteristics of Lithium Iron Phosphate (Li FePO4) batteries,
the voltage measured by all LiFePO4 batteries during charging is not the real
voltage of the batteries. Therefore, the battery voltage will drop gradually
to its real voltage after charging and disconnecting from the power source.
If there is remand to measure the battery real voltage, please charge and
disconnect the power supply and make the batteries be still for over 15
minutes, then you could start to measure the real voltage.
*Charging the Batteries
Use 14.6V lithium iron phosphate (LiFePO4) battery charger to maximize the
capacity.
Recommended charging voltage: Between 14.2V to 14.6V
Recommended charging current:
20A(0.2C) The battery will be fully charged within about 5 hours to 100%
capacity.
50A(0.5C)The battery will be fully charged within about 2 hours to 97%
capacity.
Inverter/Controller
Select “12V(14.6V)LI(LiFePO4) Mode” or
Select “Use Mode” to enter values according to the below parameters.

WARNINGS
BATTERY DISPOSAL
The electrodes of the wasted battery should be wrapped in insulation paper to
avoid fire and explosion.
PROHIBITION OF DISASSEMBLY
Never disassemble the cells.
The disassembling may generate an internal short circuit in the cell, which
may cause gassing, firing, explosion or other problems.
The electrolyte is harmful.
Li-Fe battery should not have liquid from electrolyte flowing, but in case the
electrolyte come into contact with the skin, or eyes, physicians shall slut
the electrolyte immediately with fresh water and medical advice is to be
sought.
PROHIBITION OF DUMPING OF CELLS INTO LIQUID
Do not soak the battery in the liquid, like water, seawater, non-alcoholic
drinks, fruit juice, coffee or other liquid.
PROHIBITION OF USE OF DAMAGE CELLS
If any abnormal features of the cells are found such as damage in a plastic
envelope ofthe cell, deformation of the cel package, smelling of an
electrolyte, an electrolyte orleakage and others, the cell shall never be used
anymore.
The cells with a smell of the electrolyte or leakage should be placed away
from the fire to avoid firing or explosion.
PROHIBITION OF USING IN BELOW ENVIRONMENT
Do not use the batteries in a place with strong static electricity and strong
magnetic field, otherwise it is easy to damage the battery safety protection
device and bring hidden danger.
NOTE:
This limited warranty does not cover any damage due to:
(a) transportation;
(b) storage;
(c) improper use;
(d) failure to follow the product instructions or to perform any preventive
maintenance;
(e) modifications;
(f) unauthorized repair;
(g) normal wear and tear; or
(h) external causes such as accidents, abuse, or other actions or events
beyond our reasonable control.
