Want 10kWh of power for your EcoFlow Delta 2 Max without spending $5,000? I'm showing you the "illegal" step-by-step hack to unlock expansion ports for cheap 51.2V third-party LiFePO4 batteries!
The EcoFlow Delta 2 Max is a beast, but its proprietary expansion batteries are EXPENSIVE. In this video, I reveal a simple way to add cheap third-party expansion batteries. Plus show you how to leverage the dual port design to still use your OEM EcoFlow accessories with your Delta 2 Max. While EcoFlow officially supports expansion up to 6kWh using OEM batteries, this DIY method allows us to reach a staggering 12kWh or more battery capacity! That is enough power to run your entire house through a prolonged outage!
SAFETY WARNING: Working with high-voltage DC and AC power is inherently dangerous. This can cause personal injury, death, or property destruction. This video is for entertainment purposes only. Performing this modification WILL likely void your warranty!
HUGE NEWS!!! You can now buy a pre-made adapter cable that is much safer and accomplishes exactly what you see in this video!
