Default Re: EBC-B20H 20A 12-72V Lithium Battery capacity tester just bought one

The conclusion of this battery testing machine is that it is useful for battery packs that are over 24 volts and for battery packs that you want to put more than a 2 amp load on them but it has it limitations one being that you have to have a external switching power supply for charging and your battery voltage has to be above 9 volts to able to use it

It voltage range is from 12 volts to 72 volts which works for me very well I have found a 60 volt switching power supply for this battery tester that I going to buy for it

One more note you do have to modify the fans if you can not stand for the fans to be at full speed all the time when in use
9 PC LCD Monitor
6 LCD Flat Screen TV
30 Desk Top Switching Power Supply
10 Battery Charger Switching Power Supply for Power Tool
6 18v Lithium Battery Power Boards for Tool Battery Packs
1 XBox 360 Switching Power Supply and M Board
25 Servo Drives 220/460 3 Phase
6 De-soldering Station Switching Power Supply 1 Power Supply
1 Dell Mother Board
15 Computer Power Supply
1 HP Printer Supply & Control Board * lighting finished it *

These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

1 Over Head Crane Current Sensing Board ( VFD Failure Five Years Later )
2 Hem Saw Computer Stack Board
