FAQ – Battery Pack

The lithium-ion battery is free from memory effect, this phenomenon is observed in nickel-cadmium which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.

Compare to other Batteries like NiMH or NiCd batteries, Lithium-ion cells are more expensive, because they are much more complex in manufacturing. More importantly, Li-ion batteries include special Protection circuitry to protect the battery from damage due to overcharging or over discharging. Li-ion batteries are becoming less expensive over time because best alternate available, dramatically increased the widespread adoption in multiple applications, which should see their price decrease significantly.

The lithium iron phosphate (LiFePO4) battery is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO4 as a cathode material.

This arrangement is used to classify a battery pack’s configuration in which cells are connected in Series and Parallel. For example, 4S3P means 4 cells in Series, and 3 cells in Parallel. This configuration would produce a 14.8V output voltage and capacity is three times having in single li-ion cell.

Of course, required for safety reasons. All rechargeable Li-ion or Li-po or Li-Fepo4 cells must include a protection circuit which prevents over-charging, over-discharging, short circuit protection, over temperature protection and cell balancing features etc. All Raion Battery Packs have built-in PCM or BMS to protect against above issues.

Based on the characteristics of lithium iron phosphate (LiFePO4), highly suitable for high discharge rate applications such as EV (e-bike, electric scooter, electric auto, and electric car), Power tools, Energy storage System, UPS, Emergency lighting, Solar Lighting, Solar energy system. According to different applications the design of battery pack can be customized to avail the best suited solution to satisfy the customer’s needs.

In comparison with LI-ion and Li-po battery which have cycle life is 300 cycles under normal or recommended conditions, whereas LiFePO4 battery extends cycle life up to 2000 cycles.

AH is basically Ampere Hour. Amp hour is the rating of the battery which specifies how much amperage of a battery can provide for exactly one hour. The number of amperes can vary batteries to batteries. For example, A 12.8V 6Ah Battery is used to supply power and draws current of 1 Amperes. How long will the battery last? Amp Hour = Current x Discharge Time Ah = Ampere Hour rating of battery A = Current in Amperes T = Time hrs. 6Ah = 1 A x T T = 6Ah / 1 A Time = 6 Hours

A WATT is the unit for measuring electrical power, that means the rate of doing work, in moving electrons, or an electrical potential.

Watts = Amperes x Volts.

A watt-hour (Wh) is a unit of energy, it is a method to measure the amount of work performed or generated. In a nutshell, watt-hours measure amounts of energy for a specific period of time, and watts measure rates of power at a moment in time.

Wh = W × h

For example, the energy consumption in watt-hour when the power consumption is 10 watts for time duration of 2 hours:

Wh = 10W × 2h = 20Wh

There are various applications for Battery packs such as: IoT, Smart & Portable Devices, Medical Equipment, POS, Handheld Devices, Power Tools, Automotive, Electric vehicles, Energy storage systems, Solar System, UPS, Telecom etc.
