Description

• Input voltage: 5V
• Charging cut-off voltage: 4.2V ± 1%
• maximum charge current: 1000mA
• Battery over-discharge protection voltage: 2.5V
• Battery over-current protection current: 3A
• Board size: 2.1 * 1.7CM
• Note that the charger must be able to output 1A or more when using a mobile phone charger do enter, or may not charge
• Lithium battery operating voltage: 3.6V ~4.2V

Applicable for:

• 3.6V (3.6V * 1S) lithium battery & packs
• 3.7V (3.7V * 1S) lithium battery & packs
• 4.2V (4.2V * 1S) lithium battery & packs
• Cylindrical Lithium battery (Li-ion)

Parameters:

• Maximum protection voltage: 4.255V ± 0.05V
• Minimum protection voltage: 2.35V ± 0.05V
• Maximum operating current: 2A

Protections:

• Short circuit protection
• Overcharge protection
• Over-discharge protection
• Over-current protection

Interface Definition:

• B : Battery Positive ( )
• B- : Battery Negative (-)

Note:

• Ampere meter can only be connected to 5v input end of the module.
• It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough.
• The connection wire should not be too thick.
• Make sure the connect point is good.
• If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-subs tract the charging current to avoid burn damage to chip.
• NO Reveal polarity.

Package Included:

• 1  X  5V 1A TP4056 Lithium Battery Charging Module – Micro USB
