- Thu Dec 19, 2019 8:24 am #84958 using esp8266 and a sensor i need to send data twice a day and using a lithium ion battery 3.7v .i need to have low power consumption to have a battery life so suggest me a regulator for esp8266.

thanks in advance.

Thanks for the quick reply.

Here the problem is lithium battery is showing 4.2V when it charges fully. I think we need regulator to step it down.
