The iMax B3 Compact Balance Charger is the ultimate "plug-and-play" solution for charging 2-cell (7.4V) and 3-cell (11.1V) Lithium-Polymer (LiPo) batteries. At Electrapac, we recommend this charger for RC beginners and hobbyists who want a safe, simple, and reliable way to maintain their batteries without the complexity of programmable chargers.

Product Overview

The iMax B3AC is a high-precision, budget-friendly balance charger. Unlike standard chargers that simply pump voltage into a battery, the B3AC monitors each individual cell via the balance lead. It ensures that every cell in your LiPo pack reaches exactly $4.2\text{V}$, which is critical for preventing battery puffing, fire hazards, and extending the overall life of your RC power packs.

Key Features for Electrapac Customers

• Integrated Power Supply: No need for a bulky external "brick." The B3AC plugs directly into your wall outlet using the included AC power cord.

• Automatic Balancing: The charger features independent balance ports for 2S and 3S packs. It automatically balances the voltage between cells to ensure maximum performance and safety.

• Simple LED Feedback: * Red LED: Charging in progress.

  • Green LED: Charging complete / Standby.

• Safety First: Built-in over-voltage, over-current, and short-circuit protection specifically tuned for the sensitive chemistry of LiPo batteries.

• Compact & Portable: Its small footprint makes it easy to toss into your "field bag" for charging at the track or flight field.

Charging Guide & Safety Tips

To ensure safe operation with your gear from www.electrapac.com:

1. Connection: Plug the AC cord into the charger and the wall first. The three LEDs will turn green.

2. Port Selection: Connect your battery’s white balance plug to the matching 2S or 3S port on the charger. Note: Never attempt to charge two batteries at the same time.

3. Monitor: The LEDs will turn Red to indicate charging. Once all LEDs for that battery type turn Green, the battery is fully balanced and ready for use.

4. Important: Never leave LiPo batteries charging unattended. Always charge on a fireproof surface (like a LiPo safe bag).

Primary Applications

• RC Vehicles: Perfect for charging batteries for drones, RC planes, cars, and boats.

• Airsoft: Ideal for 7.4V and 11.1V LiPo batteries used in electric airsoft guns (AEGs).

• DIY Projects: Charging 2S or 3S battery packs used to power Arduino robots or portable electronics.
