powersupply
100 W
I got 2 SmartBMS (Smart BMS 5~13 Cells in Series) from bmsbattery.com through an ES member.
http://www.bmsbattery.com/smart/330-lifepo4lithium-ion-smart-bms-for-513-cells-in-series.html
Most parts looked hand soldered, so I inspected them thoroughly.
I noticed several shorts and there were part discrepancies between the 2 boards.
Only one board turned on though it had one resistor shorted.
The other had some shorts, too, and missequipped parts which I need to replace.
Another member here had a toal of 3 SmartBMS from bmsbattery.com fail/never work.
What blew me was the greediness of bmsbattery.com.
I read that they omitted the SMD LEDs at some point, but this???
Though they advertise this SmartBMS as "Smart BMS 5~13 Cells in Series", they did ommit the 13s pin and even cable for a version ordered as 12s.
I just can urge everybody to really inspect their SmartBMS from bmsbattery.com.
And when you order, order them as 13s, so you get all the parts.

Good luck with your SmartBMS from bmsbattery.com !
