I am not able to find a solution for the battery - the official build thread says to use this

But this is nowhere to be found. Can someone help me with finding a substitute battery + charger combo?

I was planning to use a TP4056 based module

TP4056 1A Li-ion lithium Battery Charging Module With Current Protection – Type C – RoboticsDNA

roboticsdna.in roboticsdna.in
which is commonly available with a 1250 mah battery
but it looks like this module puts too much current for such a small battery
It can be modified but SMD Soldering is beyond my comfort zone
What are my other options ? Can i go ahead with the above combo?
 
The battery shield that you linked, is of a rare type because it uses a rare sized cell which is 16340, now I think this is due to the size constraints of your bot.

The similar shield for widely popular 18650 cell is available here, it will be slightly bigger, check if the size of this works for you.
