LiFePO4 That Charges Below Freezing?! Eco-Worthy Cubix 100 Pro Review

Looking for a server rack battery that doesn't fear the frost? Most LiFePO4 batteries require energy-hogging internal heaters to survive the winter, but the Eco-Worthy Cubix 100 Pro is uniquely rated for sub-freezing charging (0°C / 32°F) without them. In this video, we go deep to see if this battery lives up to the hype. We perform a full teardown to inspect the build quality, run a capacity test to verify the 5.12kWh rating, and see how it communicates with top-tier inverters like the Victron MultiPlus-II, MidNite Power AIO, and EG4 6000XP. In this video: - The Internal Look: Teardown and component inspection. - Performance: Capacity testing and inverter communication. - The Cold Factor: How it operates between 0°C and 32°F. - App Features: Monitoring your stats via the mobile app. DIY Solar Forum Article on Low Temp Charging: https://diysolarforum.com/threads/cubix-100-pro-eco-worthy-new-51-2v-100ah-server-rack-battery.119897/#post-1708972 🛠️ Parts & Components (Affiliate Links) Eco-Worthy Cubix 100 Pro 🔹 Website: https://ecoworthyus.pxf.io/KBJndz 🔹 Current Connected: https://www.currentconnected.com/product/eco-worthy-cubix-100-pro-48v-100ah-server-rack-battery/?ref=AzzpK9Fl 🔹 Amazon: https://amzn.to/48caxBb 🔹 Amazon Discount Code: ECOCUBIXPRO HURRICANE 1000V Insulated Electrician Screwdriver Set: 🔹 https://amzn.to/405ibtQ EG4 Chargeverter Plus | 48V 100A Battery Charger: 🔹 Signature Solar: https://signaturesolar.com/eg4-chargeverter-plus/?ref=adamd 💡 Coupon Code: GOINGOFFGRID50 Discount: $50 off orders over $500 🔹 Current Connected: https://www.currentconnected.com/product/eg4-chargeverter-plus-100a-outdoor-rated-48v-lithium-battery-charger/?ref=AzzpK9Fl EG4 6000XP: 🔹 Signature Solar: https://signaturesolar.com/eg4-6000xp-off-grid-inverter-split-phase/?ref=adamd 🔹 Current Connected: https://www.currentconnected.com/product/eg4-6000xp-inverter/?ref=AzzpK9Fl Victron 48V MultiPlus-II 5kVA 120V Inverter 🔹 https://www.currentconnected.com/product/victron-48v-multiplus-2-5kva-120v-inverter-70a-charger/?ref=AzzpK9Fl MidNite Power AIO Inverter 🔹 https://www.currentconnected.com/product/mnpower-theone-11-4kw-hybrid-all-in-one-inverter/?ref=AzzpK9Fl For more information, please check out my website with links to all the components, materials and products I have used in developing my off-grid solar system: https://going-off-grid.com 💡 Support the Channel Want to support my work?
