Summary 

This Battery Parallel Charger: The Ultimate Choice for FPV Enthusiasts, RC Hobbyists & Multi-Battery Device UsersDesigned specifically to solve the pain points of low efficiency, cumbersome operation, and potential safety hazards in multi-battery charging, this battery parallel charger revolutionizes the traditional single-battery charging model with its core advantages of high-speed fast charging + effortless operation + multi-layer.

Features 

🚀 8-Port High-Efficiency Parallel Charger: Fast, Safe & Hassle-Free for FPV/RC Enthusiasts
😊 8-Port High-Speed Parallel Charging
Supports simultaneous parallel charging of 8 same-model batteries! Even with non-high C-rate batteries, it safely delivers 8x the single-battery charging current with balanced fast charging—cutting charging time to just 1/8 of the original! No more long waits—fly more, practice more, and never miss a moment.
🚫 No More Frequent Battery Swaps
Eliminate the hassle of repeated battery plugging/unplugging. Enjoy an effortless one-step charging process that’s efficient and stress-free.
🧭 Precise Voltage Balancing + Boosted Efficiency
After balancing across all cells, the overall voltage difference is minimized. Just 1 balance cycle replaces 8 cycles of traditional single-battery balancing, drastically boosting charger efficiency and eliminating extra time at the end of charging—shortening total charging time even further.
🛡️ Multi-Layer Safety Protection: Charge Worry-Free
Built-in short-circuit protection, overcurrent protection, and independent fuses for each port. Fully mitigate charging risks and safeguard your batteries and devices.
🔗 Wide Compatibility with Major Chargers
Perfectly works with popular balance chargers on the market (e.g., ToolkitRC, ISDT, HotRC). No extra accessories needed—plug-and-play right out of the box.
🔒 Durable Hardware for Stable High-Current Charging
Crafted with FR-4 1.6mm thick PCB board + 2OZ thick copper foil, it safely handles 30A high current with excellent heat dissipation and long-lasting durability. Avoid overheating or damage from overload during charging.

Please Notice: 

1. It is not recommended to use batteries with a capacity difference greater than 30% in parallel charging (e.g., mixing 500mAh and 1000mAh batteries), as this will result in excessively long waiting times for balancing charging later.

2. It is not recommended to use batteries with a large voltage difference in parallel charging (e.g., mixing single 3.6V and single 3.9V batteries), as this will result in excessively long waiting times for balancing charging later.

3. Do not leave the device unattended while charging.

4. Model airplane products are not toys. Please ensure your charger is set up and the wiring is connected correctly.

5. We are not responsible for any consequences resulting from improper use.
