If you want your vanadium redox flow batteries to have a long useful life, you need to protect them from extreme temperatures. Too low temperatures (below 30 °F) call for high voltage charging while extremely high temperatures (above 90 °F) require that you reduce the charging power. Definitely, you don’t want to keep changing these parameters, so the best solution is to find other ways to protect your vanadium redox flow batteries. A good idea is to keep them in temperature-controlled battery storage containers.
