If I were to make this battery, it would weigh less than 4 kilograms. It is made with 18650 cell lithium battery, one cell weighs about 50 grams. If it is manufactured with 2000 mAh batteries, 65 batteries are required. Total weight = battery weight + packaging material and circuit protection board weight = 50*65 + packaging material and circuit protection board weight = 3250 grams + packaging material and circuit protection board weight of. the circuit protection board is ≤4000 grams
12V 100AH battery can be divided into two types of ternary lithium batteries according to the differences between individual cells: p>
The battery pack consisting of 18650 batteries weighs approximately 7.5 kg.
Battery composed of polymer batteries, approximately 4KG. (The gram/capacity ratio produced by each manufacturer is different, for reference only)
