BETAFPV1S Battery Charger Board 6 Ports Type-C Portable Charger 4.35V 1A 1S LiHV Charger for 1S RC Drone Quadcopter LiHV Battery with BT2.0/PH2.0 Connector Like 300mAh 1S Battery

Good

5 stars because if you read and follow the instructions it will do what it is intended to do. Charge your batteries to full charge. This doesn't claim to put batteries into storage or discharge. It only charges batteries. I intend to discharge my batteries manually so this is perfect for me. I used the PROPER CHARGING BRICK and everything worked out great! Don't use a normal cell phone charging brick unless you only plan to charge 2 batteries.

This thing is a lifesaver! The charger that came with my Cetus was only able to charge one single battery at a time, and that won't work for me because I have a bunch of extra batteries and need to charge multiple at a time. This has worked perfectly straight out of the box!

Works great with 30W+ Power Brick. Would be perfect if it also could put batteries into storage mode.

You have you plug this into a high power block. Also within 1 week, 1 of the 6 ports fried and is unusable to charge. So I have 5 left as of now.I mean...it works, but definitely a cheapo.

Not impressed at all

Just plug and wait it, you can see the light, easy to use

Works, but the indicator lights are annoying and counter-intuitive. For just a little more you can get a 1S charger that does storage, 4.20 and 4.35 with more input power options and better design/quality.
