Basic Performance
(1) Output with high efficiency: Standard discharge current is
0.3C-0.8C, instant impulse discharge current is 10C for 10 seconds.
(2) Good performance under high temperature, it could work under
65°C temperature.The battery structure is safe and good.
(3) Good performance under low temperature.discharge capacity
decreases to over 78% under 0°C and discharge capacity decreases to
over 70% under -20°C.
(4) Good safety performance:When the pressure inside the battery is
too large, the one-way safety valve will release gas and heat to
make sure battery perform well. When the internal pressure reaches
a certain level, the valve will be open immediately which can
protect the battery from burning and explosion.
(5) Good cycle life time, the discharge capacity is still over 80%
after 2000 cycle times of single cell(80%DOD).
(6) It can fast charging. It could be charged to 80% within 20
minutes and charged full with 2-3h.
(7) Low cost.
(8) No pollution during manufacture and usage.
Matters needing attention
(1) Please check if spare parts are completed when open the package
and read the operation manual carefully.
(2) Do not make the battery Short Circuit,do not over charge and
discharge.
(3) Please charge the new battery to full capacity before discharge
for the first use.
(4) The battery pack is fixed with plate and strip before delivery,
do not disassemble the plate and strip when using the battery.
(5) Checking the voltage of battery, normally it is 12.8V-13.2V.
(6) Fix BMS for battery pack and protect single cell to avoid over
charge and over-discharge.
(7) Rivet or screw is used for battery connector.
(8) Please use copper part to connect battery packs and fix with
hydraulic pressure plier. We could also provide the
relevantconnection which fixed with screws.
(9) The charger used should be approved by our company in order to
match with our lithium batteries.
(10) It will shorten battery cycle lifetime and damage battery due
to overcharge and over-discharge if not do according to the above .
It won’t be within our company warranty.
Requirement for safety assurance
For the sake of safety assurance, please discuss the equipment
design, its system and protection circuit of Lithium-ion cell
advance. And consult about the high rate current, rapid charge and
special application in the same way.
