If it's 2000MAH, it's 170 pieces, 10 in parallel and 17 in string.
If a single 18650 lithium battery is used, voltage 3.7V, 2000mAh, in order to meet the voltage requirement of 60/3.7 = 16.2, 16 batteries of series can be used to form a 2 Ah series. meet the capacity requirements, 20 series batteries can be used/2 = 10 series battery, a total of 16*10 = 160 18650 single lithium batteries are required.
To assemble a 60 V battery, 17 3.6 V batteries must be connected in series; 19 or 20 3.2V batteries should be connected in series.
(1) The capacity of 60v32ah lithium battery is 1920WH and the average price is about 2300 yuan
(2) The maximum voltage of this lithium battery when fully charged is approximately 66V;

(3) If this lithium battery set is used in a general electric vehicle, it phad to travel approximately 60 to 65 kilometers.
Detailed information:
Once the lithium battery cell is overcharged at a voltage above 4.2 V, will start to produce side effects. The higher the overload voltage, the higher the risk. Once the lithium battery cell voltage is higher than 4.2V, the number of lithium atoms remaining in the positive electrode material is less than half. At this time, the memory cells often collapse, causing the battery capacity to permanently decrease. If charging continues, since the storage compartment of the negative electrode has been filled with lithium atoms, subsequent lithium metal will accumulate on the surface of the negative electrode material. These lithium atoms will grow dendrites from the surface of the negative electrode towards the lithium ions.
These lithium metal crystals will pass through the separator paper and short-circuit the positive and negative electrodes. Sometimes the battery explodes before a short circuit occurs. This is because during the overcharging process, the electrolyte and other materials crack and produce gas, causing the battery shell or pressure valve to swell and rupture, allowing oxygen to escape. enter and react with lithium. the atoms accumulated on the surface of the negative electrode then explode.
