Re: powering an ESP12 with a 3.7V lipo battery cell
Posted: Sun Jan 22, 2017 6:19 am
One thing is that with Lipo batteries most of the power is used up by the time the voltage drops below about 3.6v anyway, so although they can be discharged down to 2.something volts there isn't actually that much useful power left doing that.
It might be worth considering just an LDO regulator like the XC6206, which has a dropout of 250mV, connected directly to the LIPO so will work fine down to about 3.5v.
Would be interesting to try both this and the buck/boost approach and compare the cost, weight, and actual running time.
