Introducing our 3.7 Volt Lithium Ion Battery Pack (6600 mAh) with Protection IC! This high-performance battery pack is specifically designed to meet your power needs in a compact and efficient form.

Featuring three cylindrical 18650 cells, this battery pack offers a substantial capacity of 6600 mAh, ensuring long-lasting power for your devices. With a working voltage of 3.7 Volt and a cut-off voltage of 4.35 Volt, you can rely on a stable power supply.

The Lithium Ion chemistry provides several advantages over other battery types. Firstly, it has no memory effect, meaning you can charge and discharge the batteries at any time without affecting their overall capacity. Additionally, Lithium Ion batteries have a longer storage life compared to NiMH batteries.

Despite their high capacity, these batteries are lightweight and boast a higher energy density, allowing you to power your devices without adding unnecessary bulk. The battery pack weighs just 9 ounces and has dimensions of 69mm x 54mm x 18mm (length x width x thickness).

To ensure the safety and longevity of the battery pack, it comes equipped with a Protection IC. This installed PCB (8 Amp) safeguards against overcharging, over-discharging, overdrain, and short circuits, protecting the integrity of the battery chemistry and prolonging its lifespan. Additionally, a 7 Amp polyswitch is included to limit the maximum discharging current and protect against wrong polarity.

This battery pack is perfect for a variety of applications, including building 3.7V battery packs for bike lighting, RC toys (cars and airplanes), robots, cameras, and DVD external batteries. With its PVC shrink wrap and 18 G wire leads, the battery module is well-protected and easy to integrate into your projects.

Experience the power and reliability of our 3.7 Volt Lithium Ion Battery Pack (6600 mAh) with Protection IC. It's the ideal choice for those seeking high-capacity, lightweight, and durable power solutions.
