Flow Battery's Flow Rate

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.

Which Side is Positive and Negative?

When your Flow Battery has a charged electrolyte inside of it, you can then 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 recommended for assembly of the stack to aid in the alignment of the components.
