Should model car lithium batteries use 40C or 60C?

Car model lithium battery uses 60 C.

mah value and c value, here mah represents the capacity of the battery, and C is the battery discharge rate. 1C has different concepts for batteries of different capacities (1C refers to mah value and c value). battery It can work for 1 hour with a discharge rate of 1C).

For example: Suppose there is a battery with a capacity of 2000mah which works continuously for one hour. Its average current is 2000mA, or 2A, or 1C of this battery; It's 30°C, which means the maximum discharge rate of this battery is 2X30=60A. This means this battery is safe when used at 60A. (General aircraft models will not have such a large discharge rate)

However, if the 60A battery mentioned above operates at 60C (i.e. the discharge rate maximum), I fear that it will not pshould only last two minutes. In short, the smaller the C number, the longer the maximum discharge time of the battery, so it is not enough to just look at the C number when purchasing a battery. Because this is also linked to the capacity of the battery.

Charging and discharging:

The lithium polymer battery is assembled with several cells. The voltage of each cell should be the same, so that the discharge effect is good and the discharge is good. Stable. Safety, the same voltage is called "voltage balance", so the model aircraft lithium battery charging plugs are balanced charging plugs, and a dedicated balancing charger should be used to charge them .

The 3S battery has 4 charging cables, the 4S battery has 5 charging cables, and the 6S has 7 charging cables, the number of strings plus 1. Therefore, batteries with different channel numbers havedifferent balancing plugs, so you need to choose a balancing charger suitable for the number of strings in your battery.

Voltage balance does not mean that the voltage of each cell is absolutely the same. 3.75V, 3.77V, 3.76V is not a big difference and is not a problem. Of course, the same is the best.
