Are 20700 cells the new 18650s and the Future Of Vaping ?
With the recent announcements from Tesla regarding their new cell architecture for electric road cars, will the vaping industry be making a big shift in cell selection for mods in the future ?
20700 cells and Vaping
Not long ago, the CEO of the market leading electric car manufacturers Tesla , Mr Elon Musk announced that his company would be manufacturing the most powerful and most affordable lithium ion cell to date. Electric cars have long been held back by the current generation of cells most commonly found in market, the 18650. Whilst there are other cells that are larger like the 26650 on the market, none are up to the task of increased performance and range in road cars without the added detriment of significantly increased weight. So, to this end Tesla have partnered with Panasonic to create a new compact light weight cell to deliver next gen performance for their road car programme for the next few years.
What does this mean for Vapers?
It hasn’t taken long for this new tech to trickle down to the Vaping industry. Already we know of several different brands of 20700 cells available on the vaping market. Efest ,Sanyo and Ijoy all have at least one model to market already. However, before vapers get too excited , it’s worth noting the the reputable independant battery tester Mooch has already busted false claims on many of them. So, unfortunately many of the bogus claims of continuous discharge rates that existed with 18650 cells still remain with the new 20700 cells. There are however a couple of stand out models that do offer significant gains on discharge capability over your typical 18650 cell. Both Efest and Sanyo have managed to produce models where their claims do in fact match test bench results. The IJoy 3000mAh claimed to have a 40A discharge rate but Mooch found it to have a 30A discharge rate at safe temperatures. So, even with cells with false claims attached to them, there does seem to have been a genuine increase in performance achieved when compared to the average 18650. Due to the fact that your average top of the line 18650 is capable of discharging between 20A and 25A maximum.
So do why do we need them ?
The reason this is all promising for vapers is because these cells seem to deliver on average 10A more per cell than 18650 cells. They are a comparable size at 20mm x 70mm (18650 is 18mm x 65mm on average) ,so it’s not a massive jump to assume you could now see dual battery 300w mods in the near future,and still in compact chassis. Ijoy’s new Captain P270 mod is already kicking out 234w using two of these cells and that is only a first attempt. Rumour has it DNA are already producing a 250watt chipset to take advantage of the new cells increased power range. So, you won’t necessarily need them right now, but you may find you really want them in the future. We fully expect this area of cell development to be as competitive as the 18650 market was. If it is, you could see that magical 40A rate of continuous discharge becoming available in the not too distant future. Couple that with current IPV (or regulated box mod) chipset firmware management, and you can see how we may reach and breach the 300 watt barrier pretty quickly. Not only this but you can also expect reasonable battery life and faster recharge times. Most of the new cells can recharge at 4 Amps . Sounds great to me.
