Flow Battery Flex-Stak

Disassemble and reassemble your own flow battery (Vanadium Redox Battery) stack of individually connected cells with the Flex-Stak.  The Flow Battery Flex-Stak comes in a 1-cell stack configuration that makes it easy to switch out the provided cell with your own test cell.  The stack is an excellent learning tool that gives hands-on experience with promising vanadium redox battery technology.  Whether it’s advanced research, creating your own lab or conducting professional training the Flow Battery Flex-Stak has a load of practical applications.

The Flex-Stak is a fully assembled, tested, and ready for use flow battery!  Only a flathead screwdriver and torque wrench are necessary to assemble the Flex-Stak so you can concentrate on creating your very own powered applications.

• Electrode Area: 10 cm²
• Ports: 4
• Flow Rate: 10 to 80 cc/minute at 1 Amp 1 Volt for charging
• For Charging: 1 Amp / 1 Volt
• Liquid is fed into the bottom and out the top.
• Dimensions: 3.25" x 3.25" x 2" (8.26 x 8.26 x 5.1 cm)

The Flow Battery Flex-Stak's flow rate should be started at 10 cc per minute and go up to 100 cc per minute. The overall flow rate will be determined by the state of charge of the electrolyte.

When your Flow Battery has a charged electrolyte inside of it you can than tell which side is positive and which side is negative. When charging the Flow Battery make sure that the liquid is fed into the bottom and out the top.

Please note that the Flow Battery Flex-Stak does not come with guide dowels.  1/8" guide dowels are reccommended for assembly of the stack to aid in the alignment of the components.
