Battery for GPS module

hello sir,
A7 takes 3.7V to run perfectly…It can be powered between 3.7 to 5…If i run my module for 4 to 5 hours a day and i want to run it at least 3 months or more then what is the best option available for me…

You want to run module for 4 to 5 hours, but in this time, how much data you are sending or what exactly your module is doing?
Based on that you can find it out. There are sleep modes which can be used to prolong the battery run time.
Share further details to help you better.

continously for 4 to 5 hours it sends the data using http or mqtt…it goes to sleep after that…

What size battery you are thinking to use ?

any size is fine sir…

I mean battery capacity, based on the space available for you, you have to select the battery size and capacity is linked to the size. :slight_smile:

size of bike battery is fine sir…not more than that…
