CREABEST VB002 LiFePO4 Battery 258Ah

Product description

General information
In order to achieve stable power supply even under heavy loads, lithium batteries are definitelythe best alternative to lead-acid batteries. In addition to the extremely high weight advantage, it also has a huge energy reserve, providing greater flexibility for battery connections. Creabest’s LiFePo4 battery’s built-in smart battery management system (BMS) not only protects the batteryfrom various abnormal conditions, but also monitors the charging/discharging process. Thebattery ensures a long service life and excellent discharge capacity. Compared with lead, gel or AGM batteries, it can withstand large currents, can be versatile and light in weight. In addition, the latest lithium iron technology provides a high degree of intrinsic safety, so there is no danger of explosion even under the most extreme conditions. Lithium iron phosphate batteries are the safest among conventional lithium battery types. Thenominal voltage of the lithium iron phosphate battery is 3.2V. Therefore, a 12.8V LiFePO4 batteryconsists of four batteries connected in series.

Main features

Lithium iron phosphate batteries are the chemical choice for a series of very demanding applications. Some of its functions are:

• Battery Management System (BMS) provides comprehensive protection for the battery and intelligently manages the charging/discharging
• Long service life, generally up to 7-8
• High cycle life, even in the case of regular deep discharge, the cycle life is more than 3000 times.
• No memory effect
• High energy density-larger capacity, smaller weight and
• High charging and discharging current-fast charging and discharging are
• Environmental protection, lead-free, acid-free.

Applicable fields: RV and caravan/photovoltaic, solar and renewable energy systems/Fishing, electric boat motors/power banks, camping and recreational activities.

Battery Management System (BMS)

The battery management system monitors and controls each unit of the battery to ensure that the battery is turned off in the case of undervoltage or overload, and automatically restarts immediately after the problem is corrected to prevent the battery from being damaged. Important functions of the battery management system:

•  Overload protectionIf an overload occurs, the BMS will turn off the battery output to protect the battery. The battery has no voltage at this time; when the condition returns to normal, the battery automatically returns to normal.

• Deep discharge protection
  Each cell inside the battery individually monitors the deep discharge. If this causes the battery output to be turned off, the battery can only be turned on again by charging.
  Note: Even small consumers, such as alarm systems, relays, backup systems, etc. will consume capacity and discharge the battery. If you do not use the battery for a long time, please disconnect all connections between the battery and the system.

•  Overvoltage protection
  The total charging voltage of the LIFEPO4 battery is 14.6V (the charging voltage of a single cell cannot exceed 3.65V/cell), otherwise the battery will be damaged due to overvoltage. Therefore, it is best to use a suitable charger with a final charging voltage of 14.4V-14.6V to charge the LiFePO4 battery. Although BMS can protect the battery from being overcharged, it must absorb and burn current by itself. If the charging voltage exceeds 14.6V for a long time, it will damage the BMS!

• Active battery balancing
  The built-in active balancer can adjust the battery at any time to ensure that the internal small batteries (cells) have the same voltage and extend the battery life.

• Charging control
  BMS always monitors and controls all parameters of reliable and safe charging. If something goes wrong, you can prevent charging by turning off the battery output to protect the battery.

• Battery temperature protection
  When the battery temperature is too high/low, the BMS will turn off the battery. At this time, you must first wait for the temperature to return to normal conditions, and then BMS enables the output again.

Charge and discharge warning

• If the depth of LiFePO4 discharge is too large, it may cause damage and cause Please install safety relays or isolation switches to prevent silent consumers from deep discharge.
• If the lithium battery is damaged or overcharged, the lithium battery will release harmful gases, such as
• The temperature range that the battery can be charged is 0℃ to 55℃. Charging the battery at temperatures outside this range may severely damage the battery or shorten the battery life.
• The battery can discharge temperature range is -20℃ to 60℃. Discharging the battery at a temperature outside this range may severely damage the battery or shorten battery life.

Transportation warning
Lithium batteries must be transported in the original packaging or appropriate packaging. Do not lift the battery through the connection, but only through the handle. The battery was tested according to section 38.3 (ST/SG/AC.10/11/5th edition) of Part III of the”United Nations Test and Standards Manual”. In terms of transportation, the battery belongs to UN3480 category 9 type II packaging and must comply with relevant regulations. This means that it must be packed in accordance with packing instruction P903 for land or water transportation (ADR, RID and IMDG), and air transportation (IATA) in accordance with packinginstruction P965. The original packaging meets these requirements.

Disposal/recycling of batteries

• Batteries marked with a recycling mark must be disposed of through a recognized recycling agency.
• The battery must not be disposed of together with domestic or industrial
• LiFePO4 iron phosphate batteries are subject to disposal and recycling regulations, depending on the country and region.
• Do not throw the battery into the
