My "BRICK".......
As a suggestion to you Abu....... This is a 2p sanyo lithium ion mangan 4100mah. It powers the ignition of my Zenoah 20cc.
One cell therefore has 2050 mAh, nominal 3,8 Volts. No balancing needed, safe, you can charge them in the lipo mode, You can pull them totally empty without damaging. 18 Amps current, here not needed. Easy to solder.
43grams, 18mm diameter, 65mm length
A 2s powers my electric sailplane, and two more are used to power lipo-ignitions.
