Intelligent Charging Technology for Enhanced Battery Safety

One of the primary features of this smart charger is its intelligent charging technology, which includes an integrated circuit (IC) designed to monitor the charging process and automatically cut off power once the battery reaches full capacity. This automatic cut-off ensures that the battery is neither overcharged nor undercharged, safeguarding battery health and prolonging its lifespan.

Overcharging is a common concern when it comes to lithium-ion and lithium-polymer batteries, as it can lead to reduced battery life and, in extreme cases, safety risks. With this smart charger’s IC, you can charge your battery packs with peace of mind, knowing they are charged safely and accurately. This automatic power cut-off function protects against overcharging, making the charger a dependable choice for both beginners and experienced users alike.

Multi-Voltage Input for Worldwide Compatibility

The 3.7V Li-Ion/Li-Polymer Battery Pack Smart Charger supports a wide input voltage range of 100V - 240V AC, with a frequency rating of 50/60Hz. This versatility makes it a universal charger that can be used worldwide without the need for voltage converters or adapters. Whether you’re at home, in the office, or traveling abroad, you can rely on this charger to keep your battery packs ready to go.

With a maximum input power of 6W, this charger is designed to handle a range of power sources efficiently. This feature is especially valuable for users who travel frequently and need a portable charger that works with different power standards across countries.

Optimized Output for 3.7V Li-Ion and Li-Polymer Batteries

The charger’s output is specifically tailored for 3.7V lithium-ion and lithium-polymer battery packs, providing a steady DC output of 4.2V at 0.5A (500mAh). This optimized output is ideal for safely charging batteries with capacities above 700 mAh, ensuring efficient and consistent charging without risking damage to the battery cells.

The 0.5A output current strikes a balance between charging speed and battery longevity, charging your battery packs effectively without causing heat build-up or degradation. The charger’s steady output is ideal for those who need their batteries charged promptly but also want to prioritize long-term battery health.

User-Friendly LED Indicators for Real-Time Charging Status

For easy monitoring, this smart charger is equipped with dual LED indicators that provide real-time feedback on the charging status. The red LED light illuminates when the battery is charging, and a green LED light appears once charging is complete. This intuitive LED system allows you to monitor the charging process at a glance, so you know when your battery is ready to be used again.

The clear charging status indicator is particularly useful for users with multiple batteries, as it enables quick and easy monitoring without the need for additional testing equipment. This feature is ideal for anyone who relies on multiple battery packs, as it makes it simple to track which batteries are fully charged and ready for action.

Compact, Lightweight, and Portable Design

With dimensions of just 88mm x 52mm x 30mm (3.5" x 2" x 1.2") and a weight of only 4.9 oz (139 g), this charger is both compact and lightweight. Its small size makes it ideal for portable applications, especially in the RC hobby community, where users need a charger that is easy to carry and store. Whether you’re charging batteries for RC air or car models, or using it for other battery-powered devices, this charger’s portability ensures it can go wherever you need it.

This compact form factor also makes the charger easy to pack into travel bags, tool kits, or RC model cases. The small size is particularly useful for hobbyists and professionals who need a portable charging solution that can be quickly set up and used without taking up much space.

Versatile Connector with Clip Adapter

The 3.7V Li-Ion/Li-Polymer Battery Pack Smart Charger features a 4' 11" long 5.5 x 2.1 x 12mm male barrel connector, providing a flexible connection for a wide range of battery pack types. It also includes a connector adapter from a 5.5mm x 2.1mm female barrel plug to clips, allowing you to easily connect the charger to battery packs with wire leads. This versatility in connector types means you have the flexibility to charge various battery packs, making it convenient for users with multiple devices.

The clip adapter offers added convenience by enabling you to attach the charger to battery packs that don’t have a compatible barrel connector, which is common with certain RC battery configurations. This adaptability ensures that you can use the charger with different battery setups without needing additional adapters or connectors.

Calculating Charge Time for Accurate Monitoring

One of the advantages of this charger is its precise charge time calculation formula. The charge time is calculated as follows: (Ah rating of the pack x 1.5) / 0.5A charge current. This formula allows users to estimate the time needed to fully charge their battery packs, which is helpful for planning purposes, especially for users who need to charge multiple batteries in a timely manner.

For instance, if you have a 1500mAh battery pack, the charge time would be approximately 4.5 hours:

(1.5Ah×1.5)/0.5A=4.5 hours(1.5Ah \times 1.5) / 0.5A = 4.5 \text{ hours}(1.5Ah×1.5)/0.5A=4.5 hours

This formula is a valuable tool for users who need to plan their charging schedules, as it ensures they know when their batteries will be ready for use.
