hello dear members, i recently purchased a powerbank that states it has 12000mah capacity, however when fully charged it charges my sgs3 only once which has 3600mah battery. i would really love to increase the charge capacity of this powerbank, i opened the case and images are attached
now the thing is i have quite a lot of cellphone batteries (3.7v but different mah) roaming around here, can i somehow use them to extend the backup? or how can i use more cells like these to increase backup? i dont really care about the look of it i just need more backup hoping i will be able to do it. thanks
