I believe the current performance is rather good, but 18650 is the premium size (or was, the 20xxx/21xxx looks to be the new premium size), i.e. all the big manufacturers have made their best cells in that size.
Yeah, I know the best manufacturers have made the best 18650 cells already. What I was hoping is that “the rest of the world” AKA Aspire in this case, would have made a comparable cell to the great 18650’s for a lower price. I’m just surprised and saddened that it seems the 18650 tech has been at its peak forever, yet nobody can catch up and give us a better price.
P.S. I agree current performance seems good for this cell, but at the price of capacity less than 2Ah? Not really great.
A lil off-topic question aimed at electronic device experts like ;-) Henrik, though battery related too. I am to convert an old incandescent Petzl headlamp to led. Can I use a battery management system circuit as an electronic switch? It seems to me that if I install a little switch in the anode to P+/B+ input line of the BMS, it should work right, doesn't it?
Should be an extremely reliable switch, no need for it to handle any significant amount of power.
Cheers :-)
P.S.: not a bad battery, but LG HB6 cells are pretty inexpensive and handle current a little bit better despite the slightly lower capacity.
