Most of us have something in place since the winter of 2022 when the power outages were systematic due to russian strikes on civilians and infrastructure, amplified by lack of air defence. Most of us needed to work though so some got UPS, EcoFlows, generators, solar systems, even DIY batteries if the budget is low. This year it's more of the same.

What DIY batteries? Have you considered the new sodium/aluminum battery type? I am wondering if that battery could be easy to DIY because sodium and aluminum are cheap and available.

DIY batteries here are usually battery banks assembled from Chinese LiFePo4 cells, plus a Chinese BMS.
