SKYRC E3 AC 2S~3S Li-Po Battery Balance Charger (V2)

The SKYRC E3 AC is a compact dual-channel AC balance charger specifically engineered for 2S and 3S lithium polymer battery packs, delivering independent charging control with integrated cell balancing circuitry. Professional RC hobbyists, drone pilots, and FPV racing enthusiasts rely on this charger to maintain optimal battery health and extend cycle life through precision voltage regulation and real-time cell monitoring. This product solves the critical problem of cell voltage imbalance in multi-cell Li-Po batteries, which causes premature capacity loss, reduced flight time, and potential safety hazards during discharge.

Product Overview

The SKYRC E3 AC V2 operates on a dual independent charging channel architecture, allowing simultaneous charging of two separate battery packs at controlled amperage rates up to 2A per channel. The charger employs active cell balancing technology that monitors individual cell voltages during the charging cycle, automatically redistributing charge between cells to achieve voltage equalization within 0.05V tolerance. This microprocessor-controlled approach prevents overcharging of high-voltage cells while ensuring complete charge acceptance, directly improving battery longevity and performance consistency across repeated charge cycles.

The V2 iteration introduces enhanced AC input compatibility with universal voltage input ranging from 100V to 240V AC, making it suitable for global use without step-down transformers. The charger features intelligent temperature monitoring with automatic charge termination if internal temperatures exceed safe thresholds, protecting both the battery pack and the charger electronics. LED status indicators provide real-time feedback on charging progress, cell balance status, and fault conditions, eliminating guesswork during the charging process.

How to Use

Begin by connecting the SKYRC E3 AC charger to a standard AC power outlet using the integrated power cable. Verify that the input voltage indicator illuminates, confirming proper AC supply detection. Locate the balance connector on your Li-Po battery pack, which features a JST-XH connector with individual cell taps. Insert the balance connector into the appropriate charging port on the charger face, ensuring the connector seats fully until you feel a positive click.

Select your desired charging current using the front panel controls, starting with 1A for initial charges and adjusting up to 2A for faster charging on larger capacity packs. Press the start button to initiate the charging cycle. The charger will automatically detect battery type and cell count, displaying the charge status via LED indicators. During charging, the balance circuit continuously monitors cell voltages and redistributes charge as needed. The charging cycle completes automatically when all cells reach 4.2V nominal voltage, at which point the charger enters trickle charge mode and eventually terminates with an audible beep and LED status change. Allow the battery to cool for 15 minutes before use in high-performance applications.

Frequently Asked Questions

Can I charge 2S and 3S batteries simultaneously on different channels?

Yes, the SKYRC E3 AC features two completely independent charging channels. You can charge a 2S battery pack on channel one while simultaneously charging a 3S battery pack on channel two. Each channel has independent current adjustment, allowing you to optimize charging parameters for different battery capacities and cell counts without interference between channels.

What is the maximum charging time for a typical 2200mAh 3S battery pack?

At maximum charging current of 2A, a 2200mAh 3S battery pack will require approximately 1.5 to 2 hours to fully charge, accounting for the charger's constant current phase followed by trickle charge termination. Charging time scales linearly with battery capacity, so a 1100mAh pack charges in approximately 45 minutes to 1 hour at 2A. For battery longevity, charging at 1A is recommended for storage between flights, extending overall cell lifespan.

How does the cell balancing function work during charging?

The SKYRC E3 AC monitors voltage across each individual cell through the balance connector throughout the charging process. When it detects voltage differences exceeding 0.05V between cells, the internal balancing circuit automatically shunts excess charge from higher voltage cells to lower voltage cells through precision resistor networks. This active balancing ensures all cells reach 4.2V nominal voltage simultaneously, preventing cell overstress and maximizing usable capacity across the entire pack.

Is this charger safe to leave unattended during charging?

The SKYRC E3 AC incorporates multiple safety features including temperature monitoring, overcharge protection, and short-circuit detection. However, we recommend monitoring the charger during initial use to familiarize yourself with normal operation indicators. Never leave the charger unattended in high-temperature environments or if the charger shows unusual thermal behavior. Always charge in well-ventilated areas away from flammable materials.
