If you consider buying this battery you may face problem with broken unit as I did so watch the video before you make an order.

I bought it on March 2033 at WULILLS Official Store on AliExpress.com site and this video shows how it performance look like.

This #Wulills #battery #lifepo4 has a serious problem with quality. Possibly cell are not top -balanced or BMS is damaged because it can not handle even smallest load despite the fact that I was charged using 2 different chargers:

than 7 hours using 12A 12V Foxur battery charger in LiFePo4 mode.
