J'ai une question s'il vous plaît, il faut combien d'accu de 21700 5000mah pour faire une batterie de 48V?

[@rosalina6082]

Ik heb een vraag: hoeveel 21700 5000mAh-batterijen heb je nodig om een ​​48V-batterij te maken?

[@gulsmvlogs4170]

For 48v 13s battery you will 13 rows of cells, if you have 4 cells in a row that 13x4= 52 cells. It depends on how much capacity you want, for good capacity for e-bike you need to have 6-8 cell in a row, I think, you can find many videos of 48v battery on youtube.

[@rosalina6082]

Thank you for your response, by the way my problem is that I have a 48V battery with 21700 5000mah batteries, but I don't know the exact amperage because there is nothing displayed on the battery?

[@gulsmvlogs4170]

@@rosalina6082 I could not understand "because there is nothing displayed on the battery?"

[@rosalina6082]

I'll explain to you, I bought a battery except that I don't know anything about this battery, there is no indication. I tested the battery with a multimeter it shows 54V

[@gulsmvlogs4170]

A 48v battery should show higher voltage on fully charge, so a 48v battery can show 54v.

What batteries did you use?

[@gulsmvlogs4170]

NCR 18650, 3400 mAh

[@rosalina6082]

But I don't know if it's 10Ah, 15Ah or 20 the only thing that has it is battery 21700, 5000mah

[@gulsmvlogs4170]

I am confused! Do you have a battery pack or just single 21700 cell?

[@gulsmvlogs4170]

You should 1st try to find them in your local market, just need to make sure they are original. If not then you can buy from aliexpress, read the reviews of other buyers, but they can get quite expensive with the shipping fee I think!
