Hi Morne, What model Pylontech's are these, with the water and under voltage cell issues? Reason I ask is I have a few U2000 and U3000 cases with working bms's, and the cable/software to scan Pylontechs. Bought due to my own battery issues a few months ago. Fortunately, my other four swollen U2000s and two U3000 batteries were warrenty replaced by Pylontech after 5 years in service. All were replaced with U3000Cs. I'm not too far from you, just next to Swartkops air force base.
