charging 3s at 12.6v. Notice the 3rd resistor open for 3S.
Arrived in less than a month. No custom duty. Used Ekart logistics in India._Bought 2 items in separate order 6s Version.___Pros:_1. Supports 100w charging and discharging. Not tested 140w. _2. Very less heating. This could be due to 6s version.__Cons:_1. While charging the batteries, not able to charge properly with normal USB A to USB C. It only pulls 0.6 - 1 amps at 5v max whereas the charger has capability to produce higher amps and voltage as well._2. While charging, the USB testing meters show low WH reading. Tried multiple USB testers. But while output, it shows correct values._3. It frequently cuts off power and restores while charging Samsung phones. But not other phones or laptops.__Average product. Good considering the price.__
