Thanks. Been waiting for this! Using this battery chemistry, I’m pretty sure they could make a 3500mah 18650 with close to 30Q performance…or a 40S with 30T performance.
So this is a rewrapped Samsung INR21700-50S, doesn't it?
20A continuous? Seriously? According to HKJ's graph, the cell overheats a bit before full discharge with cut-off at +50°C (this is equal to 75°C with 25°C ambient temperature). Typical maximum allowed cell temperature is 80°C, so… a bit tight, imho.
I see there's been an overall improvement in discharge performance, this is great as it means less heat or energy lost in the batteries as the current flows. However, how about energy density? They better get on it now that there's barely any oil to extract… O:)
If you need capacity, 50G, Molicel M50 or even sofirn’s 5000mA 21700s if you want cheap prices and decent performance seeing as how there’s a shortage of Samsung cells. 40T, Molicel P42A for higher drain. 30T for absolute max output with multi 50.2 fet lights
Well I don’t see it being available in the next 3 months, maybe we’ll get lucky in 6 months or near the end of the year. There’s a major battery shortage going on right now. Check the typical American battery sellers. No stock of a lot of Samsung, LG, Sony cells.
