Great little product

Great product. Power is supplied by a buck converter powered by the solar panel. Works perfectly. Very efficient use of energy and the batteries are charged perfectly.

Pros
  • Sturdy construction
Cons
  • Not as thick as other picks

Works great, but the problem is that it only .

Works great but the problem is you can only charge at 12.1V instead of 12.6V and the battery cuts out at 10V instead of 9V. This means you will get weaker and less power from your battery. .

Pros
  • New
Cons
  • Long delivery time

Essential for Li-Ion/Lipo projects

Cool stuff. He's really small and does what he says. I use it for a Li-ion battery I made, it works great. I soldered the balance plug to the pads on mine and connected the battery directly to the balance jack. Update: One of my lithium cells dropped to 2.9V and wouldn't turn off, who cares!

Pros
  • Absolute legend
Cons
  • Useless features

Works mostly as advertised but with a few issues. .

Works mostly as advertised but with some issues. I use it to charge 3 18650 batteries. The only limitation I can find is that it doesn't protect against undervoltage. I ran a discharge test by running the app on battery power to see how long it takes for the voltage to drop and this allowed my battery's total voltage to reach 5.5V, meaning my three cells each had about 1.8V. Lipo should *never* be discharged below 2.5V, and below 1V they are permanently damaged. Mine are probably recoverable…

Pros
  • Easy setup
Cons
  • Modern

Works for my needs - power supply accessory

I built a Bluetooth portable stereo system using two 3" Dayton Audio speakers and a 50W Bluetooth board. Before purchasing this charging board I bought several others from China, ebay and Revain and none of them worked properly, if at all. This board worked the first time I plugged it in and has been for 10 months. I didn't check the voltage readings as I didn't have to. I used the same 18650 batteries in a 3S configuration and the system works just as well as the first day I plugged everything

Pros
  • High marks for support and durability from testers
Cons
  • Some flaws

Awesome power accessory board

I used it to make a LIPO battery protection circuit and surge protector for my 3S lipos drone. I have about a dozen different batteries with different capacities (1500-3000 mAh) and sometimes the cells are out of balance and not charging properly with the balance charger. I am using two car headlight bulbs, each drawing about 5 amps, and this board to fully discharge a battery that is not balanced and then charge it from the lowest safe voltage after which it will start balancing the charge…

Pros
  • Elegant design
Cons
  • Volume
