I need help about this cellphone battery.

[iQuace]

I saw this on facebook. He sell this for $16 - $20. Base on his words, He parallel connected 3 pieces of 1800mAh battery.

I want to know how to create this.

Thanks

Someone correct me if I'm wrong. If you have multiple LiPo cells, you need a balance charger. 3 1800mAh cells in parallel will charge with a standard charger but will have a longer charge time. Possibly 3 to 4 hours at 1A, that's just a guess. However, all the cells may not charge evenly thus the need for a balance charger. I suppose you could connect diodes to each battery and have 3 different charge ports to get all of them at max capacity. <-- yet another guess...

Here please read this:

As for how to create this pack, you just need the 3 1800mAh cells. Connect all the red (+) together, then connect all the black (-) together. You now have a parallel connection on your battery pack. Be mindful that heat is an enemy to LiPo cells. They can overheat and either catch fire and/or explode on you.
