Today I presenting you the possible scam warning about LifePo4 12 Volts 200 Ah batery from AliExpress brad name WULILLS. I will discuss quality and performance on capacity test. 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 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: NOCO Genius 10 in lithium iron phosphate mode - 2h shows FULL than 7 hours using 12A 12V Foxur battery charger in LiFePo4 mode. Chapters 0:00 Intro 0:43 Voltage Display and charging 2:00 Preparing load test with inverter and bulb 3:23 Voltage drop on broken battery 4:21 Same load test on lead-acid car battery 5:26 Conclusion Battery can provide maximum 50 Watts of power , everything above causes voltage drop and #BMS restart. I will keeo you updated about this matter in the future.
