GENERAL ADVANTAGES OF LITHIUM ION BATTERY

1. Smaller and lighter: Li-ion battery is lighter than other rechargeable batteries in consideration of battery capacity. This makes it more practical in portable consumer electronic devices in which physical specifications such as weight and form factor are considered important selling points.

2. High energy density: Li-ion battery has higher energy density than other rechargeable batteries. This means having high power capacity without being too bulky. This is suitable for use in power-hungry devices such as laptops and smartphones. Advancements in technology open potential for higher capacities.

3. Low self-discharge: Li-ion battery also has a low self-discharge rate of about 1.5 percent per month. This means that the battery has a longer shelf life when not in used because it discharges slowly than other rechargeable batteries. Take note that nickel-metal hydride battery has a self-discharge of 20 percent per month.

4. Zero to low memory effect: Li-ion battery has zero to minimal memory effect. Take note than memory effect is a phenomenon observed in rechargeable batteries in which they lose their maximum energy capacity when repeated recharged after being only partially discharged. This memory effect is common in nickel-metal hydride rechargeable batteries such as NiCd and NiMH.

5. Quick charging: Li-ion battery is quicker to charge than other rechargeable batteries. It actually takes a fraction of a time to charge when compared to counterparts.

6. High open-circuit voltage: Li-ion battery has a chemistry that results in higher open-circuit voltage than other aqueous batteries such as lead acid, nickel-metal hydride, and nickel-cadmium.

7. Longer lifespan: Li-ion battery can typically handle hundreds of charge-discharge cycles. Some lithium ion batteries loss 30 percent of their capacity after 1000 cycles while more advanced lithium ion batteries still have better capacity only after 5000 cycles.

What is a BMS?

For example :


BMS stands for battery management system, this is the brain of our deep cycle lithium battery. The BMS protects the lithium cells from getting damaged in several scenarios. From low or high voltage, low or high temperatures, or if there is a short in the system. The BMS will shut off the battery to protect the li-ion cells and the user of the battery from unsafe operating conditions.

The BMS also regulates the amount of power you can take out of the battery. The BMS on our 100 amp-hour battery is rated to 100 amps continuous, 200 amps for 30 seconds and any higher loads for ½ second.

BMS also keeps all of the cells in balance. At the top of each charge cycle, the BMS reduces the charging rate in cells that have been topped off first, letting the rest of the cells catch up. This ensures that the cells are always in balance, and maintains the quality and efficiency of the pack.
