Lithium ion Battery Connector Types

Abstract:

Lithium ion battery connector types can be diverse for various applications and fields.

Connectors are used for charging/discharging purpose in various working environments and conditions.

Some lithium ion batteries use 1 connector for both charging and dischargeing, some lithium ion batteries use 1 connector for charging and 1 connector for discharging.

Lithium ion Battery Connector in various applications

Ebike battery connector types

Ebike Battery Charge Connector

Most common charge connectors on ebike battery are XLR and DC5521 as below picture shows.

XLR Connector
ebike battery connector types Ebike-Battery-Charger-Connector-XLR-connector

XLR connector are widely use on silver fish type ebike battery, good for 1-5A continuous charge current.

DC5521 Connector

DC5521 connector are widely used on downtube type ebike battery, rear rack ebike battery and inner tube ebike battery, good for 1-3A continuous charge current; there is DC5525 connector good for 1-5A continuous charge current.

Ebike Battery Discharge Connector

Ebike battery internal discharge connector usuallly are blade pin type or round pin type as below picture shows, 1 part installed on the battery body and another part installed on the mouting base.

The most common ebike battery internal discharge connectors are usually customized type which are designed by the ebike battery housing manufactures.

Lithium battery connector types

JST series, Molex series, DC series connectors are usually used on small lithium battery pack(<100Wh) with small charge/discharge current, usually < 10A.

XT series, Anderson series connectors are used used on medium lithium battery pack with discharge current between 10A-100A.

Module series connector are mainly used on module battery or big battery with dicharge current > 100A.

Waterproof series connector are mainly used on waterproof lithium battery which requires IP65/IP67/IP68 grade waterproof ability.
