Synsynk batteries

Does anyone have any experience with these? Anything to be concerned about?

Asking for a friend…

They have a decent warranty when paired with a SS inverter. Just make sure to read the warranty terms. 10 years on cells, 5 years on the BMS…

The Sunsynk 5.12 and 10kw batteries were never true sunsynk batteries and they were 0.5C.
the battery were chosen by Herholds and rebranded as being Sunsynk.

The new 5.32 Sunsynk battery on the other hand is true Sunsynk with a 1C rating.
