Before throwing away damaged or old LiPo batteries, you should first drain them completely until there is no charge left. In this article I will show you how to build a battery discharger using high power resistors.
There are many reasons why you want to discharge LiPo batteries. Maybe you have fully charged LiPo left after a flight session, or maybe you want to discharge the battery completely for disposal. In this article I will show you a few simple ways to discharge your LiPo batteries.
During the latency testing on the Frsky X-Lite, we discovered some interesting results. There is delay in the gimbals, (how often the gimbal value is being updated), and additional delay caused by OpenTX’s sample averaging.
LC filter is one of the most basic filters in electroincs, which comprises of just one inductor and one capacitor in its simplest form. This circuit is widely used by FPV hobbyists to suppress noise in power created by ESC and motors. Read More
The Frsky X-Lite has an external module bay that is too small to fit standard size JR modules including the TBS Crossfire. Are we giving up that easily? HELL NO! A few people have been taking the X-Lite apart as soon as they received the the first batch, and trying to find out whether they can get it working.
Mr Markus Grocholewski shared some amazing photos with me where they took at 36Km above ground using a balloon. The shots are simply breathtaking, so I asked him why and how he managed to send a balloon and camera to space.
iSDT LiPo chargers are great and I’ve been recommending them a lot, but they aren’t the most accurate when it comes to voltage reading. The error is usually quite small and shouldn’t be something to worry about. But it’s always good to check and here is how you can calibrate a iSDT LiPo Charger.
In the new Gopro Hero 5 Session camera updates, they removed the option to change Shutter Speed. You need to install the older 1.5 firmware to have this option back.
Very annoyingly the Foxeer and Caddx FPV cameras don’t have a OSD ground pin. Especially the cable that comes with it have male connectors on both ends making it nearly useless for me. In order to use the camera and play with the settings at the same time, I had to make a DIY cable that breaks out the OSD signal and GND.
If you accidentally damage your 2.4GHz receiver antenna in a crash or by spinning propellers, don’t worry! You can easily fix it without buying a whole new receiver or replacement antenna. And there are considerations about the length of the antenna you should know about.
In this tutorial I will show you how to make FPV Goggles Battery Connector for connecting different power sources and batteries. This hack will make battery charging easier, and allows you to use LiPo batteries that come with standard discharge connectors.
I will show you how to build a DIY LiPo Battery discharger easily with 12V halogen light bulbs. It’s capable of discharging 2S, 3S, 4S, 5S and 6S LiPo batteries.
