Need BMS suggesting for array of 20 Lithium Ion 48v 15.6Ah batteries

[Wackestone]

Hello,

I have 20 of these batteries bought from a surplus supplier. I am not sure what kind of BMS I need to wire these properly so they will be monitored and also be capable amp-wise.

Thank You!

if you had 20 of these in parallel you would need 20 BMS. I think i would try them without a bms. It does not look like they use one with the e-bikes

Thank you Craig. This can be a bit intimidating to get started and I wasn't sure about this.

What are you intending on using these for? Multiple ebikes? Some ebike batteries come with inexpensive BMSs. The leads on that one look very thin and I cannot tell from the website if it has an integral BMS. It is a 13S configuration so I would investigate further to understand the charging parameters before I charged them. Did they come with a charger?

I was planning on pairing them with some solar panels a solar charge controller and an inverter for an emergency power bank. Investigating them beyond this has been difficult as information on them is sparse.
