Model No:- Semco SI HT 3563A 12CH 300V - Semco Battery IR Tester=high-accuracy battery internal resistance tester is designed for the new measurement requirements of the battery industry. It is special for measurement use in low resistance batteries, large-scale lithium battery packs and fast product sorting in production lines. With the technology advantage of Semco in battery internal resistance testing for many years.

When the lithium battery is assembled or the finished battery pack is stored for a long time, the voltage between the individual cells is inconsistent due to the difference of static power consumption of each circuit of the protection plate and the self- discharge rate of each single cell. During the charging process, the voltage rise speed of each cell is different, which results in the increase of the voltage difference of the battery pack. The highest voltage series of single body triggers the BMS over- voltage protection in advance, which causes the whole group of batteries to stop charging. The low voltage monomer cannot be full of electricity, and the high voltage monomer cannot discharge the power. The battery capacity is reduced and the life is reduced. Equalization is the key technology to solve the difference of cell unit. The common methods are discharge equalization and charging equilibrium. The balance has the effect of balancing voltage on the lithium battery group, so as to achieve the effect of full charge and full discharge of battery capacity, and make the battery group recover the maximum capacity and extend the service life of the battery pack.

Battery Active-Balancer is a balanced management system tailored for large-capacity series battery packs. The Balancer USES ultracapacitors as the medium to balance the active energy transfer.

The Balancer is suitable for 2 ～ 24 series battery packs, with the functions of voltage collection and balance. The balancer operates with a constant balance-current of 15A for energy transfer. The balance -current does not depend on the delta-voltage of the battery cells in series. Cell voltage acquisition range 1 V ~ 5V, accuracy ±3mV.Applicable to Li-ion, Lipo, Lifepo4, LTO and other battery on the market.

The balancer is equipped with Bluetooth communication function and supports mobile APP software. The balancer can be connected to the phone via Bluetooth to check the individual battery voltage, balance state, modify parameters and other operations. The balancer is small in size and easy to carry. It can be widely used in the battery PACK of small sightseeing car, scooter, sharing car, high-power energy storage, base station backup power supply, solar power station and other products. It can also be used in battery balance maintenance, repair and other occasions.
