Build Your Own Li-ion Battery Pack

I need a battery for my selfmade catamaran. It´s a smal boat (2x4m). For this a Li-ion battery with 700Wh is big enought.

Step 1: Choose a Battery Box

I bought a batterybox from aliexpress. It´s for 60 pcs. 18650 cells.

Watch the Video. It Shows a cheap box for only 45$. You can use it also for an e-bike.
