also the problem with the VTC6 is that they seem to have a bad cycle life. Should mean they perform great when they are new and after like 25 charge cycles they are not better than a HG2 anymore.
Here is the discharge curve to compare Sony VTC6 to Samsung 30Q.
I’m not sure what his methods are. Henrik details his methods on his website and his results usually match my own test results using an iCharger duo 4010with temp sensors in a large temperature controlled room. I say usually because I am in bed and cannot confirm that the curves matched in my tests (I did them a few months ago).
Problem with 30Q is that since they are only rated at 15A their performance could change from batch to batch.
The current tests show that the batches so far are capable of much more - but that does not have to stay this way.
I kinda want to cycle the cells I have now until they have 40-50 cycles and test again. I usually don’t do this since for my work purposes, they’re a one time disposable use cell… (Can you believe there are no primary lithium cells that are more energy dense?!? (In volume))
Shamefully, they’re tied to a government contract so we have to store them in our back shop in case they come knocking on the door for everything once the project is finished.
Plus theyre all welded in massive burly packs. Maybe good for ebikes, definitely no good for eskate
I don’t have any graphs or anything, but I can tell you this–using them in mech mods for vaping (the type with no chips or regulation, just an atomizer directly connected to the battery controlled by the ohms of the coils you build: lower ohms=faster battery drain and more amps pulled), and I can tell you this; I’ve used all the batteries discussed here besides eFest (all the major brands, Samsung, LG, Sony) and by FAR the Sonys light these things up the fastest and with the most power. They’re the best by far. Samsung’s are good, for sure, then the LG’s, but the Sonys come closest to having the actual current amperage as advertised. The others? Sometimes I think they pick a number between the constant current and surge amps and try passing it off. I don’t have the links but I’ve seen the numbers and tests done on YouTube. But that’s direct battery to device, I don’t think you can get a better guage than that. Anyway, that’s my two cents
I don’t see how or why nobody goes for A123 cells. Yes they are a little bigger being a 26650 size cell but the benefits of discharge and fire safety seem to be the best. Also you can build smaller packs.
Lame excuse. Same with 30q’s
So how much does it cost when your board catches fire.Seem like packs could be half as big to get the same discharge. A group buy could get em down to 6.00 while the 30q’s are 3.50 each.
