Hi—I’m wondering if the new E-Series for LTE M1 will allow us to get away with smaller batteries. In my application, putting sensors on surfboard/paddleboard/kayak fins for coastal ocean data exploration (https://blog.particle.io/2018/06/19/smartfin/), battery size is a limiting factor in what we can put our sensors into.
A 500 mAh battery (with extra capacitors, I suppose?) would fit in many more things than a 2,000 or even 1,000 mAh battery, simply due to our admittedly somewhat insane dimensional restrictions. Users can recharge the device after every use so that isn’t as much of a concern.
In searching the forum, I found a few threads, most notably this one (Powering Electron with Li-SOCl2 Batteries (and no LiPo cell)) where I saw @ScruffR’s note:
So I’m a little discouraged from trying a smaller battery with (super)capacitor, knowing that the E-Series 3G needs ~ 2 A peak, but curious if anyone has a suggested workaround or knowledge of lower power requirements for the E-Series LTE M1 or even with the 3G.
