The Henge 6A UBEC utilizes a switching power supply design, offering several key advantages over traditional linear BECs, especially when using batteries of 3 cells (11.1V) or higher:
Higher Efficiency & Lower Heat Generation:
For example, when using a 4-cell LiPo battery (approximately 14.8V), a traditional linear regulator producing 5V/1A output requires an input of 1A at the battery side, resulting in:
Thus, efficiency is only 33.8%, with the remaining 9.8W lost as heat. This excessive heat may trigger the BEC's thermal protection, causing shutdown and malfunction.
In contrast, the Henge UBEC with a switching regulator only needs about 0.37A from the battery to deliver the same output (5V/1A), resulting in:
Thus, the overall efficiency is 91.3%, significantly reducing heat generation and improving system reliability.
Ease of Installation (ESC with internal BEC):
Ease of Installation (ESC without internal BEC):
Although various measures have been taken to minimize electromagnetic interference (EMI), a small amount of EMI is still unavoidable when using switching regulator-type UBECs. To ensure stable receiver operation, please keep the UBEC’s output ferrite ring as far away as possible from the main control board (avoid stacking the ferrite ring on top of the main control board). Additionally, position the entire UBEC unit at the maximum possible distance from the receiver.
Use a small, pointed screwdriver to carefully remove the red wire from the ESC connector. Once removed, make sure to insulate it properly to avoid short circuits. If you ever need to reuse the ESC’s internal BEC functionality, simply reconnect the red wire into its original position.
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.
Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
