The number of 18650 batteries needed for a 12V 60Ah solar street light depends on the voltage and capacity of each battery. Generally, the voltage of 18650 battery is 3.7V and the capacity is 2500mAh.
First of all, we need to convert the voltage of the solar street light into the voltage of the battery. Since the voltage of 18650 battery is 3.7V and the voltage of solar street light is 12V, we need to convert 12V to 3.7V.
12V ÷ 3.7V ≈ 3 ,24
Next, we need to convert the capacity of the solar street light into the capacity of the battery. Since the capacity of the 18650 battery is 2500 mAh and the capacity of the solar street light is 60 Ah, we need to convert 60 Ah to mAh.
60AH × 1000 ≈ 60000mAh
We then divide the battery capacity by the capacity of each cell to determine the number of cells needed.
60000mAh ÷ 2500mAh ≈ 24
Therefore, a floor lampaire 12V60AH requires approximately 24 18650 batteries.
If you want to purchase these batteries, you can do so in the quantity you need. Please note that this is only an estimate and actual quantities may vary as battery efficiency, losses and other factors must be taken into account. Additionally, it is recommended to choose reliable brands and suppliers when purchasing batteries to ensure quality and performance.
96 or 72 are acceptable.
Assembly Notes:
1. A 2V battery is generally composed of 4 strings, and the capacity of a single 18650 is 1200~3400 mAh.
2. If you use a more cost-effective 2500mAh premium battery, you need 24 batteries in parallel and 4 in series, for a total of 96 batteries.
3. If you use the best Panasonic 3400mAH, it will be 18 in parallel and 4 in series, a total ofe 72.
4. The current maximum capacity of 18650 battery will not exceed 3500 mAh.
5. Anything beyond the mark is definitely fake. Products like Shenhuo 4800, 5200, 9800, etc. are all counterfeits.
