Hi, I'm looking for LiFePO4 batteries that are compatible with the Growatt SPF5000ES, AND are available in Spain....

I found Pylontech batteries, but I'm not sure if they are compatible.

Any suggestions?

Any LiFePo4 battery with a nominal 48v is compatible.
Unless you want BMS communications.
Which is usually more trouble than benefit.

Also Pylontech batteries are 15s. And not recommended by most members here.
You're better off with a 16s battery.

Ah, thanks for the info. What exactly is 15s vs 16s? And I thought BMS is THE way to go

Yes, you need a BMS.
You just don't have to use BMS communications.
(When the BMS tells the AIO how and when to charge the battery)
