SKYRC B6Neo: Balance Lipo Battery Charger for 1S-6S Lipo/Li-Ion/LiHV, 1-15S NiMH/NiCd - DC 200W, PD 80W, Smart Battery Charger, Discharger and Storage (Blue-Red) TYPE C

Next-Generation Miniaturized Power Architecture

The SkyRC B6neo represents a technological leap forward in high-density DC power electronics and battery management. Measuring a mere 70 by 50 by 32 millimeters and tipping the scales at just 82 grams, the B6neo condenses benchtop-grade multi-chemistry battery charging into an ultra-compact form factor smaller than a standard credit card footprint. Engineered specifically for RC hobbyists, field robotics engineers, and drone pilots who demand extreme portability without compromising on throughput, the B6neo integrates a sophisticated synchronous buck-boost converter topology capable of delivering up to 200W under direct DC input and up to 80W when powered via modern USB Power Delivery (USB-PD 3.0) and Quick Charge protocols.

Constructed within an impact-resistant, flame-retardant PC-ABS V0 polymer enclosure, the B6neo is purpose-built to withstand the rigors of field operations while isolating internal electronics from external mechanical shock and environmental stress. The charging system is controlled by an advanced high-speed micro-controller unit (MCU) executing custom state-machine firmware. This embedded controller continuously monitors input bus stability, duty-cycle thermal shifts, internal shunt temperatures, and per-cell delta-peak or voltage-cutoff thresholds at millivolt accuracy, ensuring both optimal energy transfer efficiency and total operational safety.

High-Fidelity ColorX Visual Interface and Navigation

Human-machine interaction is mediated via SkyRC's proprietary ColorX user interface displayed on a vibrant 1.77-inch TN color screen. Operating at a resolution of 128 by 160 pixels with 262,000 selectable colors, the screen provides high-contrast, sunlight-readable real-time telemetry. Key charging parameters—such as overall pack voltage, per-cell individual voltages, charged capacity (in milliamp-hours), instantaneous charging amperage, internal pack resistance, and elapsed cycle time—are rendered via clean, distinct color-coded graphical blocks. Navigation is handled through a three-button tactile membrane switch system located beneath the display, allowing intuitive cycling between configuration menus, chemical profiles, cut-off thresholds, and operating modes without the convoluted multi-tier navigation trees characteristic of older legacy chargers.

Dual Input Architecture: High-Power DC and Universal USB-PD

To deliver maximum operational flexibility across laboratory, field, and emergency charging scenarios, the SkyRC B6neo incorporates a dual-source power input architecture. The primary power bus uses an industry-standard XT60 male interface configured to accept an unregulated DC input spectrum ranging from 10.0V to 28.0V. When connected to high-capacity DC power supplies, deep-cycle lead-acid field batteries, or high-capacity 4S-6S LiPo packs, the B6neo achieves its maximum power output of 200W, driving charge currents up to an impressive 10.0A.

For ultra-light travel and field scenarios where carrying a bulky dedicated DC power supply is impractical, the B6neo features an auxiliary USB Type-C input utilizing advanced hardware PD/QC negotiation chips. Supporting both USB Power Delivery 3.0 and Quick Charge 3.0 standards, the charger can negotiate input rails from 12.0V up to 20.0V at current limits specified by the host supply, outputting a maximum of 80W charge power. This allows users to power the B6neo directly from modern GaN wall adapters, high-output USB-C power banks, or automotive USB-C accessory jacks.

Precision Multi-Chemistry Charging and Active Balancing Engine

The SkyRC B6neo supports virtually every primary rechargeable electrochemical composition utilized in modern electronics and RC platforms. Supported chemistries include Lithium Polymer (LiPo), High-Voltage Lithium Polymer (LiHV), Lithium Iron Phosphate (LiFe), Lithium-Ion (Li-Ion), Nickel-Metal Hydride (NiMH), Nickel-Cadmium (NiCd), and Lead-Acid (Pb). Cell count capability spans from 1S to 6S for all lithium-based chemistries, 1 to 15 cells for nickel-based chemistries, and 3S to 6S (6V to 12V nominal) for lead-acid formulations.

Balancing precision is maintained through an integrated, board-level active balancing subsystem capable of sinking up to 500mA per cell. By shunting excess charge current around fully balanced cells during the constant-voltage (CV) charging phase, the B6neo eliminates inter-cell voltage discrepancies with exceptional speed, extending battery longevity and maximizing flight or run times. In addition, the balance port serves an active diagnostic role: with the balance lead connected, the unit functions as an internal resistance (IR) meter and battery state-of-charge checker, revealing individual cell degradation before a weak cell fails under load.

Integrated Multi-Function Discharging and Storage Conditioning

Battery maintenance is critical for extending cell health, particularly for lithium formulations that suffer accelerated degradation when stored at full charge. The B6neo features a comprehensive set of auxiliary operational modes, including Discharge, Storage, and automated Cycling. In standard discharge mode, the unit utilizes internal passive dissipation to discharge packs at currents from 0.1A to 2.0A up to a thermal limit of 10W. However, when an external balance lead is connected, the intelligent power-sharing circuit raises the allowable discharge power limit up to 24W, significantly accelerating the process of bringing flight packs down to a stable 3.80V-3.85V per cell storage state after an aborted mission.

Regulated Digital DC Benchtop Power Supply Mode

Transcending the functionality of a standalone battery charger, the B6neo includes a programmable DC Power Supply mode. Through this software-driven mode, the user can configure the XT60 output port to act as an adjustable, current-limited bench power supply. The voltage can be set with 0.1V precision across a wide range, while current limits can be dialed from 0.1A to 10.0A. This allows hardware engineers and service technicians to power prototypes, drive DC soldering irons, test brushed motors, and verify low-voltage circuit functionality without requiring a dedicated benchtop supply unit.

Acoustic and Thermal Optimization

High power density naturally generates localized thermal buildup. To counteract this, the B6neo features an internal aluminum finned heat sink paired with a high-RPM miniature hydraulic-bearing cooling fan. Smart thermal throttling firmware regulates fan speed dynamically based on internal NTC thermistor feedback. Operating at full thermal load, noise emissions remain strictly capped around 48 decibels, ensuring a quiet bench environment during sustained charging operations. If internal temperatures exceed safe operating limits due to restricted airflow, the charger automatically derates output current before triggering safety shutdown protocols.

Comprehensive Port Interface and Pinout Analysis

The SkyRC B6neo features five primary physical interfaces designed for high reliability and zero-insertion-error connectivity:

1. DC Input Port (XT60 Male): Located on the input side panel, this polarized high-current connector accepts direct DC supplies between 10.0V and 28.0V. The flat side corresponds to positive voltage (+), while the chamfered/angled side corresponds to negative ground (-). Capable of sustaining input currents up to 15A continuous.

2. USB Type-C Input and Data Port: Located alongside the DC input, this 24-pin reversible Type-C female receptacle supports PD3.0 and QC inputs from 12V to 20V. In addition to power input, this port interfaces with a host PC running the SkyRC Charger Master application, allowing bi-directional telemetry logging and MCU firmware updates.

3. Main Output Port (XT60 Female): Positioned on the output panel, this port connects to the primary battery leads. It delivers regulated charge currents from 0.1A to 10.0A and supports programmable DC power output. Like the input port, the flat housing edge designates the positive terminal (+), and the chamfered edge designates the ground terminal (-).

4. 6S JST-XH Balance Port: An integrated 7-pin keyed JST-XH socket configured for direct connection of 2S through 6S balance plugs without requiring an external balance board. Pinout architecture follows standard industry convention from ground upward: Pin 1 (far right, marked negative) connects to Battery Ground / Pack Negative; Pin 2 connects to Cell 1 Positive; Pin 3 connects to Cell 2 Positive; Pin 4 connects to Cell 3 Positive; Pin 5 connects to Cell 4 Positive; Pin 6 connects to Cell 5 Positive; and Pin 7 connects to Cell 6 Positive / Pack Positive. When connecting 2S to 5S packs, the connector must be aligned flush to the negative (Pin 1) reference.

5. Micro Fan Exhaust Port: Precision-milled directional ventilation slots located on the rear and underside of the housing to facilitate laminar exhaust airflow through the heatsink array.
