V2 Parallel Charging Board for Simultaneous 4-Pack LiPo Battery Charging up to 35A

For enthusiasts of RC cars, drones, and model aircraft, managing the charging of multiple lithium polymer (LiPo) battery packs can be a repetitive and time-consuming task. The V2 parallel charging board is designed to streamline this process. It functions as an expansion adapter, allowing you to connect and balance charge up to four individual battery packs in a single operation, provided they share the same cell configuration. This consolidates several individual charging sessions, significantly reducing overall charging time and simplifying your workflow between runs or flights. The board is built to handle the demands of high-performance hobbies, supporting substantial charging currents.

Features and Construction

The V2 board's design prioritises both performance and safety for parallel charging applications. Its construction incorporates components chosen to ensure reliable power delivery and user protection during the charging process.

Material and Build

The board's core is a printed circuit board (PCB) utilising thicker copper foil, a design choice that facilitates the high-current charging it supports, up to 35A. Electrical connections are made via high-quality gold-plated connectors, which aim to provide a consistent and corrosion-resistant contact point. The output line for the critical balance port is constructed from flexible and durable 18AWG multi-strand silicone wire.

Size and Practical Fit

While specific physical dimensions are not provided, the board is designed as a central charging hub. It features multiple connection points for main power leads and balance ports, organised to accommodate up to four battery packs. The included silicone caps for the T-plug connectors are a practical addition for storage and safety, helping to keep the unit tidy and protected when not all ports are in use.

Uses and Placement

This charging adapter serves a specific function within the workflow of power-intensive remote-controlled hobbies, fitting seamlessly into workshop, pit area, or home charging stations.

Event or Professional Use

During race days, flying sessions, or professional filming with drones, rapid battery turnaround is often essential. This board enables users to charge a full set of batteries—enough for multiple vehicles or aircraft—simultaneously after a session. This means less time waiting for batteries to charge sequentially and more time being operational. The ability to charge at up to 35A (when supported by your charger and batteries) can further accelerate the preparation process.

Everyday Home Use

For the hobbyist at home, the board simplifies post-run maintenance. Instead of repeatedly swapping batteries on a single charger, you can connect all depleted packs at once. The parallel charging process also has a stated benefit for balance time; when multiple single cells are connected in parallel, the average voltage difference between them after a weak discharge is smaller, which can effectively shorten the overall balance charging phase.

Benefits and Buying Value

The value of this parallel charging board lies in its time-saving efficiency and integrated safety features, offering a practical upgrade to a standard single-port charging setup.

Reuse and Low Maintenance

The board is a durable tool designed for repeated use across many charging cycles. Its safety features, like the 40A fuses between battery groups, are built-in protections that help safeguard your investment in both the board and your expensive LiPo batteries. The provided silicone caps contribute to low maintenance by protecting the connector ports from dust and accidental damage.

Why Choose This Product

This V2 parallel charging board is a solution for anyone looking to reduce the downtime associated with charging multiple LiPo batteries. Its key differentiators are the capacity to charge four packs at once and its robust build for high-current applications (up to 35A). The inclusion of protective fuses and safety caps demonstrates a design that considers real-world risks like voltage imbalance and accidental short circuits. It is a logically sound choice for expanding the capability of an existing compatible balance charger.
