Technical Performance

The eTronix ParaBoard ET0289 represents a significant step forward in battery charging infrastructure for RC enthusiasts across the UK and beyond. At its core, the board utilises a two-ounce copper PCB construction, which is substantially heavier and more conductive than standard circuit boards, allowing it to dissipate heat more effectively and handle larger current loads without voltage drop or performance degradation. The heavily tinned main power circuit further enhances conductivity and protects against corrosion, ensuring that the board maintains peak performance even after years of regular use in active RC charging environments. The parallel wiring configuration means that all three charging ports operate independently yet simultaneously, each capable of delivering full charging current to its connected battery pack without any interaction or prioritisation between ports. This engineering approach ensures that whether you're charging a single 2S pack, a combination of 2S and 4S batteries, or three 6S packs simultaneously, each battery receives consistent, uninterrupted charging current. The board has undergone comprehensive testing at 20 Amps continuous current, representing real-world charging scenarios with modern balance chargers, and has been certified as safe for peak loads up to 30 Amps for short periods of 10 to 30 minutes, covering virtually every conceivable use case for serious RC hobbyists. The EC3 connectors selected for the main power circuit are among the most reliable in the industry, featuring secure positive and negative contacts that maintain excellent electrical connection through hundreds of charge cycles. The XH balance connectors similarly offer proven reliability and universal compatibility with battery packs from every major RC battery manufacturer.

Frequently Asked Questions

• Can I charge batteries with different cell counts at the same time on the ParaBoard? — No, it is essential that all battery packs connected to the board simultaneously have exactly the same cell count (all 2S, all 3S, all 4S, etc). Mixing different cell counts on the same board can result in improper charging, damage to batteries, and potential safety hazards. Always verify that all connected batteries are identical in cell configuration before starting a charging session.
• What is the maximum charging current I can safely use with the ParaBoard? — The board has been fully tested and certified to safely handle continuous charging currents up to 20 Amps. It can accommodate peak currents of up to 30 Amps for short periods of 10 to 30 minutes. When using your balance charger, set the charging current to match your batteries' specifications and never exceed the 20 Amp continuous rating for extended charging sessions.
• Is the ParaBoard suitable for beginners new to RC charging? — Absolutely. The ParaBoard is designed with user simplicity in mind. Since the board arrives fully pre-wired in parallel configuration, you simply need to plug your battery connectors into the ports and connect the board to your balance charger. There is no complex wiring, soldering or technical knowledge required. However, ensure you understand basic LiPo battery safety practices and always use a quality balance charger with the board.
• Can I use this board with any balance charger? — The ParaBoard is compatible with any balance charger that features EC3 connector compatibility and can deliver current to multiple battery packs simultaneously. The board itself is charger-agnostic; it simply provides the parallel infrastructure. Ensure your charger has sufficient output capacity to handle three batteries at your desired charging current.
• What makes the two-ounce copper PCB better than standard boards? — Two-ounce copper refers to the weight of copper per square foot of board material, indicating substantially thicker copper traces than standard PCBs. This increased copper mass means better electrical conductivity, more efficient current distribution, superior heat dissipation, and dramatically improved durability under high-current applications. In practical terms, you get a board that runs cooler, lasts longer, and performs more reliably throughout its service life.
• How many times can I charge batteries using the ParaBoard before it wears out? — The ParaBoard is engineered for long-term durability and will reliably support hundreds of charge cycles without degradation, provided you use it within its rated specifications (20 Amp continuous, 30 Amp peak). The selected high-quality components and robust construction mean this board will outlast many of the batteries you charge with it.
• What is the difference between the ParaBoard and charging batteries sequentially? — Charging sequentially means charging one battery completely, then moving to the next, which can consume hours of your RC time. The ParaBoard enables parallel charging of up to three packs simultaneously, reducing total charging time from potentially three hours down to one hour, allowing you to spend more time enjoying your RC vehicles and less time waiting for batteries.
