Lithium-ion batteries Advantage

 

Lithium-ion batteries are a much newer technology, and they improve on lead-acid in multiple ways. Their largest advantage is improved lifespan, with faster charge and discharge times. They are light weight, compact, easier to install, longer life. They have an improved depth of discharge and charge. Also, they perform better both in low and high temperatures than lead-acid. however, lithium batteries cost much more upfront than lead-acid. the longer lifecycle of this battery means that despite a higher initial investment, the battery may cost less over its lifecycle. Additionally, lithium-ion batteries is much safe with protection circuits and charge & discharge controllers etc.

Structure


VICT designed the block type module structure to uniform the battery module size and simplify the assembly process.

Pouch cells are well held and protected in an anti-frame plastic frame block with necessary foams for vibration absorption.

Here are two of metal sheet bars on above the cells and fixed to the top of frame block, cell tabs go through the metal bars

and lay down for the laser welding to firmly attached to the metal bars as a parallel configuration method of cells, metal bars

also have screw holes for further connection among blocks. Here are extra top lids for blocks, after blocks are assembled with

bus bars and wires, the plastic lid can be installed for isolation and protection but will not disturb the current connections and wires.

 

Application

Emergency power supply, LED light, Electric vehicle, Golf cart, Lawn Mower, Power tool etc.

Battery care and maintenance


• When battery pack is fully discharged and turned off automatically, please do not use it any more until it is
recharged. Over discharge the battery pack means battery life will be shortened and the battery may become
permanently damaged.
• When battery pack is fully discharged and turned off automatically, please recharge it in time (Within 12 hours),
even charge 2~5% electricity to the pack will protect the cycle life well.
• We suggest charge up to 90% SOC and discharge no less than 20% SOC when using to prolong the cycle life.
When the voltage of single cell drop down to 3.3V or the actual capacity is lower than 20%, please recharge
the battery promptly.
• If the battery pack will not be used for a long time (several days or weeks), please disconnect the Anderson
connector from the load. (When battery pack connected to the load, the pack is always “waiting for” running,
which will consume the electricity and make battery fully discharged and damaged.)
• Please discharge and recharge the battery timely after kept for more than 2 months so that the battery cycle
life would be much longer. The cycle life of li-ion battery would be shorted if the battery alway be kept as fully
charged state. For long time storage, keep the battery as 40 ~ 60% state of charge (SOC) and discharge and
charge every 2 or 3 months. The temperature for long time storage is 15°C ~ 30°C.
• The battery pack can be used at -15~50°C for discharge, 0~45°C for charge, while the best working
temperature for this battery pack is 15~40°C. Please take some necessary procedures, like heating & cooling
system, or use heat insulation materials to stop cold effect battery pack in winter.
• When the temperature is more than 75°C (Internal temperature of the battery), the battery cycle life would be
shorted. So do not exposure the battery under the sun during summer.
• When the temperature is under -15°C or lower, the battery performance would be effect and the cycle life might
be shorted.
• Battery should be kept under dry and ventilation condition. Do not put the battery close to fire and explosive
products. When charging the battery, cut of the load.
• Do not wash the battery shell with organic solvent. If there’s fire accident, please do not use CO2 to extinguish
the fire but use CCl4 or sand soil.
• Please handle the pack with care and gently to avoid severe vibration, throw or drop.
