In the hope that it will be useful to the future work of folks here, I've written up as much as possible about my experience patching up a failing ZCell and nursing it along. I've also included some further general notes about Redflow's hardware and software:

The ultimate demise of my last Redflow ZCell -
New member introduction thread!Hi All,
Tim here. I'm a software engineer by trade with some electronics/hardware/electrical knowledge (no chemistry to speak of though). I'm interested in flow batteries because I think they are in general a better idea for long-term stationary energy storage than lithium. I've had three+ years experience at my home with Redflow ZCells hooked up to Victron inverter/charger gear, and have written rather a lot of blog posts about this, some of which @kirk has quoted here in the past. The latest is https://ourobengr.com/2025/08/yeah-that-went-well/ which includes some speculation about why Redflow's zinc bromine flow batteries may fail, and some possible mitigations. Not sure exactly how best I can help yet, but I'd love to see an open source flow battery get off the ground
