Genew/ Smart 5G pocket wifi Battery Spacer Filler

This is a battery spacer / filler that I create for Genew branded 5G pocket wifi, that is sold by Smart Communication in the Philippines, this was created as I am not able to find any replacement model for this pocket wifi and had to use a battery of smaller capacity and form factor, in order to prevent e battery from moving around iI created this spacer/filler, the battery I use H15G battery pictured below with 3600MAh which was used for pocket wifi model M20h M20 M26g M26hg M27G M27HG.
