[11.1V 2600mAh – 28.86Wh Rechargeable Battery]

Designed as a replacement battery for compatible Altec Lansing Super LifeJacket IMW888 Series and Super LifeJacket Jolt IMW889 Series portable speakers.

This rechargeable 3S1P Li-ion battery pack uses three 18650 cells to provide 11.1V nominal voltage, 2600mAh capacity, and 28.86Wh of energy.

Compatible speaker models include:

• Super LifeJacket: IMW888, IMW888-BLG, IMW888S
• Super LifeJacket Jolt: IMW889, IMW889N, IMW889N-BLKC

Equipped with a JST-XH 2-pin connector, the battery is designed for compatible devices requiring the same voltage, connector configuration, polarity, dimensions, and electrical specifications.

Important: Verify the original battery's voltage, connector type, polarity, physical dimensions, and charging requirements before ordering. Compatibility cannot be determined by speaker model number alone.

[Built-In 5A BMS Protection & 10KΩ NTC Thermistor]

The battery pack features an integrated Battery Management System (BMS) rated for 5A continuous discharge, together with a built-in 10KΩ NTC thermistor for temperature monitoring.

The BMS is designed to provide protection against:

• Overcharge
• Over-discharge
• Overcurrent
• Short circuit

The 10KΩ NTC thermistor supports battery temperature monitoring when used with compatible equipment.

The integrated protection system helps promote safe and reliable battery operation when used with compatible devices and an appropriate Li-ion charging system.

[Safe Charging & Handling]
