Deep Cycle Battery

Chilwee BN Series Lithium Ion Battery Pack is designed based on MnNiCo Ternary technology with excellent cycle performance and high safety. BN Series is mainly applied to electric bicycles, tricycles and other electric vehicles. The battery pack is comprised of soft-packed battery cells in series and battery protection module is included to ensure supreme reliability.

In the process of battery use, the percentage of the battery's discharge capacity to its rated capacity is called the depth of discharge. The depth of discharge has a deep relationship with the charging life of the secondary battery (storage battery or rechargeable battery). The deeper the depth of discharge of the secondary battery, the shorter the charging life, which will result in a shorter battery life Therefore, deep discharge should be avoided as much as possible.

Lead-acid batteries are deep-charged and deep-discharged within 400 times, with a life of about two years. Lithium batteries are more durable and slow to consume. They are charged and discharged more than 500 times and have a life of 4-5 years.

Lithium-ion battery has no memory effect, the depth of charge and discharge does not affect the capacity of the battery, and it is convenient to use.
