Wanptek Official Store, AliExpress, are claiming that battery backlash/recoil depending on translation, is the reason why my bench psu failed after just a few minutes at 20A CC (27.6V). KPS3020D model.
They're now just sending the "Order ID - STATUS Finished" logo when I message.
Aside from the fact I appear to be dealing with rogues.
Has anyone else had problems with these units or this company? Any suggestions on how to handle this. It's beyond my 15 days.
I have a heap of batteries to try and balance and the summer is running out.
I don't have a mains power supply to connect to, solar is all there is here.
I'm trying to balance at 12V 4S using my old 12V 45A psu but that's messing with the BMS (JKB2a8s20p) as it thinks the previous cells are the new set and shows spurious data.
What was set up to be a straight forward operation is potentially going to leave me with no power for the winter and probably no heating as I will have to spend my firewood money to buy a new psu.
