Lots of FPV cameras require a 7-13V input, which is fine if your setup is using 3S LiPo. For those running 4S, you'll need to use a step down voltage regulator and look no further than this one. This miniature linear regulator is designed to output 12V at up to 300mA from a 4S LiPo battery, without ripples or noise. A small amount of soldering is required, but it couldn't be simpler and all of the solder points are clearly labeled. The regulator itself has a tiny form factor, so it is suitable for even the smallest of builds.
We also sell the regulator integrated into a mini PDB here.
- Input: 4S LiPo (14-17v)

- 1x Linear Regulator 4S LiPo to 12V 300mA
Learn about voltage regulation: Supplying your electrical components with the correct voltage is crucial for their operation. LiPo battery cells are rated at 3.7 volts per cell, therefore a range of voltages are available, leading from 3.7v (1S) to 44.4v (12S). A 3 cell 11.1v pack is widely employed as it provides a handy voltage for many electronics without the need to regulate. However, more powerful multirotors require LiPos with greater voltages; 6S (22.2v) is common for octocopters, thus voltage regulation is necessary to supply power to auxiliary components, such as the: receiver, flight controller, camera, transmitter and lights etc.
There are two types of regulators, linear and switching. A linear regulator works by taking the difference between the input and output voltages, and just burning it up as waste heat. The larger the difference between the input and output voltage, the more heat produced. This is the reason why linear regulators are usually only compatible with up to 3S LiPos. Linear regulators typically operate with efficiencies of 40%, reaching as low as 14%. On the other hand, switching regulators are far more efficient. They work by storing pulses of energy taken from the battery in a capacitor and then releasing it. This is accomplished with the help of an electrical switch and a controller, which regulates the rate at which energy is transferred to the output (hence the term “switching regulator”). The energy losses involved in moving chunks of energy around in this way are relatively small, and the result is that a switching regulator can typically have 85% efficiency. Since their efficiency is less dependent on input voltage, they are compatible with higher voltage LiPos. While they are preferable to linear regulators you should consider their placement within the UAV carefully, as in some cases the switching noise can cause interference with the receiver.
Within a multirotor context, the term "BEC" (Battery Eliminator Circuit) is exchangeable with voltage regulator. The use of a BEC negates the traditional need for a separate battery to power you flight auxiliaries, for example a receiver. Most speed controllers (Not OPTO ESCs) incorporate an internal 5v linear BEC, so that simply plugging the ESC into the receiver is all you need to supply power to it. However, as mentioned above they only work well under low loads and at low voltages. For higher voltage/current applications it is recommended to use a stand-alone SBEC - that way you reduce the risk of a brownout (a term used to describe the temporary loss of function of the radio receiver due to the supply voltage dropping too low). Confusion often surrounds the difference between a UBEC and an SBEC, however they are both the same thing - a switching voltage regulator. "UBEC" was once a specific brand name for one of the original switching BECs, so the more correct generic term is actually SBEC.
COVID-19: We are still shipping out orders daily, but have changed our same day shipping cut-off time to 1PM to help cope with demand. If an order is placed after 1PM we will still do our best to ship same day as our daily postal collection is around 4:15.
Please be aware that deliveries with Royal Mail are taking longer to get through. At the moment we are finding it can range from next day to even up to two weeks, with 3-5 days being typical. So if you choose Royal Mail as a shipping method please be patient, shipments aren’t going missing they are just taking a while to get through the postal service. For fast deliveries we recommend choosing DHL.
All information relating to shipping and delivery is stated here. Should you not find what you are looking for, please contact us.
Shipping costs are calculated once items have been placed in your basket during checkout.
UK Postage: Here at Flying Tech we process orders Monday to Friday and pride ourselves on our quick turnaround of orders. If stocks levels allow, we aim to dispatch orders placed before 4PM the same day with Royal Mail. Our cut off time for courier delivery is earlier; orders must be placed by 1PM for next day delivery with DHL and 1PM for next day delivery with APC. A confirmation email will be sent when your order has been dispatched. If you wish to change your order, please contact us promptly, as we won't be able to make amendments once the order has been shipped.
We are partnered with several delivery companies including Royal Mail, DHL, APC and Parcel Force. If you have a special delivery requirement or would like to arrange a shop collection please contact us. For small low value orders our cheapest delivery service is Royal Mail First Class; this service aims to deliver the next working day including Saturdays and it can be sent recorded for extra peace of mind – please note this is not a guaranteed next day delivery or trackable service.
For a guaranteed next day delivery we recommend Royal Mail Special Delivery or one of our courier delivery options. Royal Mail Special Delivery will arrive by 1PM the next day and for an extra fee can be delivered on Saturdays. APC Overnight offers next day delivery with full tracking and a 2hr time slot pre-delivery text notification. DHL is a good option for larger consignments and remote locations such as Northern Ireland and Isle of Man. All high value orders are fully insured and will likely require a signature on delivery.
FREE shipping in the UK on orders over £99 (this is a signed for service and insured to a maximum of £40). Please note that the offer only applies to orders with a total weight under 1Kg and that a few products are exempt from the offer, such as LiPo batteries.
International Postage: We are based in the UK, but ship to most worldwide destinations. Postage rates are calculated by the weight and shipment location, the price is quoted during the checkout. Low value order can be sent by Air Mail, but are not insured. Higher value, heavy goods will be sent with DHL or an alternative courier. Orders shipped outside the EU may be subject to customs charges. These charges are additional to any delivery costs and will need to be paid by the recipient.
For our international customers who require a rapid delivery we off a DHL Express service. DHL Express offers NEXT DAY delivery to most European destinations and a very fast delivery for countries further afield, generally 2-3 days. For country specific estimated transit times, please refer this download.
We reserve the right to modify, remove or add to any of these services at any time. We endeavour to ship all items as fast as possible. If you would like an alternative shipping arrangement to be made please contact us.
