thanks for all the advice. I just ordered 2 of the battery on the link due to the same problem with my ezbook. Will report back later.
Interestingly, there’s other batteries from the same seller that in the reviews section looks like lots of people have installed in their ezbook 3 pros… cant find an example right now but i guess its being done. the 2x6600MAH seems the highest capacity though.
I also ordered this charger since shitty charger may screw up the battery. (tip: message the seller for power cable of your country)
