Can you REALLY mix different battery sizes and brands in one solar bank? They said it was impossible (and dangerous), but I built a 100kWh DIY "Tower of Power" to prove them wrong.
In this video, I’m giving you a full, in-depth tour of my massive 100+kWh LiFePO4 battery storage system. We are breaking the "golden rule" of solar by mixing and matching different battery capacities and brands—including LiTime, Watt Cycle, and EEL Battery. I’ll show you the exact wiring strategy, overcurrent protection, and custom DIY battery cables I used to make this system safe, reliable, and incredibly budget-friendly.
Whether you’re building a whole-home backup or an off-grid power system, learning how to safely mix mismatched batteries is the ultimate "money-saving" skill for DIY solar enthusiasts!

E-bike savings are real, and in this video I break down how an e-bike plus solar saves me $988 per year using actual numbers. I also test the Mokwheel Onyx in the real world, including range, hill climbing, braking, comfort, and whether this flagship e-bike is worth buying.
