Displaying the current value is as easy as reading the sense resistor voltage drop and displaying the corresponding I = Vsense / Rsense value, no big fuzz really. Just matter of a few extra lines of microcontroller code any widespread and cheap multimeter already has. Actual weighted per unit cost: negligible.
There are really a whole bunch of chargers. What sets the Lii-100 apart from the rest is the occasional stupid low price with code. The display will simply increase cost, so I cannot imagine this charger being as cheap as the original, so it looses its primary advantage.
I really love a voltage display, but to me this is initially of interest if I charge multiple cells at once from one light to check if the cells have discharged evenly. So for a single cell this is of no interest.
Nevertheless, it is a good looking charger, and it still is cheap. Certainly will keep an eye on this one nevertheless. :sunglasses:
My 100B (the one without power bank function) actually does not overcharge cells like the 100 does. I wonder if it’s the power bank circuitry that’s to blame somehow. Maybe this S1 will not overcharge because it has no power bank function?
The display features indicators for lithium chemistries: this is termination voltage adjustment. There's no charging parameter or algorithm ambiguity for Ni-MH thence no need for an indicator.
The powerbank function may be a bit tricky with the rail and contact resistances getting in the way.
Sure it looks nice, but what’s the use of it?
I just put my cells in a charger and that’s it. I’m not going to watch the numbers on the charger for several hours.
What I would like is time remaining until 100%
