What is the difference between Cells and batteries?

Cell means a single electrochemical power supply or voltage. They have a variety of sizes and chemical types, directly determine the rated capacity and rated voltage of the battery respectively. when many of the batteries of the same size and chemical type are connected together in a variety of configurations to produce higher voltages and / or capacities, Thus, becomes a battery . batteries in series increases the output voltage, while battery in parallel increases the output capacity.

What is primary battery and rechargeable battery ?

A primary battery that can only use for one time, also means non-rechargeable battery  while the secondary battery can be used repeatedly ,it is also called rechargeable battery. All lithium metal batteries are non-rechargeable（ primary battery）, and all lithium-ion batteries are rechargeable (secondary batteries.）.

What is smart battery?

SMART battery is a battery pack with an integrated gas counting circuit and a two-wire interface that allows the battery to communicate with the host device, this is to read the battery charging state, health state, maintenance, preferred charging method and so on.

What is the difference between an Amp-Hour and a Watt-Hour?

All cells and batteries, as the electrical potential of the electrochemical source, can only be called electrical potential, as long as inside the battery, he chemicals create that potential exist .. Once the cell or battery is connected to the device, the power supply begins and the current begins to flow through the device, consuming the potential cell or the chemical in the cell or batteries. Therefore, it is necessary to clarify how much chemical substances are present in the batteries or batteries, so that the equipment designer and the user know how long the equipment is powered by the cell or the battery. This is the capacity or energy of the cells or batteries.

Capacity is represented by Amperage, energy is represented by wattage. To understand these units of measurement, we should know the way of discharge. Typically, the safety and characteristics of a cell or battery are tested by using a constant current discharge, where the amperage is the primary unit of measurement. Device with constant power requirements using wattage as the main unit of measurement. Thus, the capacity and energy levels can tell the user how long it takes to discharge of cell or battery as if knowing they units of measurement.

What is the difference between lithium-ion batteries and LiFePO4?

The iron phosphate battery is actually a lithium iron phosphate battery. Lithium iron phosphate (LiFePO4) is a rechargeable lithium chemical using a liquid electrolyte. This makes the lithium iron phosphate battery just another type of lithium-ion battery. Like many other lithium-ion chemicals,iron phosphate has its own advantages over certain areas of other chemicals.

The two major advantages of iron phosphate are usage cycles and its safety. Lithium iron phosphate (LiFePO4) is lower than the charge voltage of other lithium ion chemicals. therefore we will not see the level of electrolyte decomposition occurring at higher potentials. This significantly increases the battery or battery cycle life. Standard lithium ion chemicals typically have a service life of 300 to 500 cycles, where iron phosphate is known to reach 3000 cycles, with a typical life expectancy greater than 1500 cycles. Lithium iron phosphate does not undergo exothermic reactions at high temperatures, which means that, like other lithium-ion battery chemicals, if the protection method fails, predictable abuse,such as short circuit and accidental overcharge, the thermal runaway will not happen.
