Stop overpaying for proprietary batteries! I finally cracked the code on the EcoFlow expansion port. In this video, I show you exactly how to bypass the expensive OEM ecosystem and add massive, cheap LiFePO4 battery storage to your EcoFlow power station for pennies on the dollar.
The Secret: It all comes down to a simple $0.40 component—a 1k Ohm resistor—that tricks the Battery Management System (BMS) into unlocking the extra battery port.
Here’s what you are going to learn in this video:
The "Resistor Hack" Method: How to fabricate a simple DIY cable to jump the communication pins and enable voltage input.
The "Splice" Method: How to tap into your existing EcoFlow extra battery cable to run BOTH OEM and cheap external batteries simultaneously!
Step-by-Step Guide: Complete wiring instruction and safety tips for connecting external cheap 48V LiFePO4 batteries.
This works on the Delta series and potentially others.
For the record: I'm not anti-EcoFlow or their batteries! In fact, I LOVE them! I have promoted their stuff without any requests from them heavily on my channel! I just think there are ways some people can save some money on their setups and make their money go further. Also, there are situations where the OEM batteries are still a much better solution!
HUGE NEWS!!! You can now buy a pre-made adapter cable that is much safer and accomplishes exactly what you see in this video!

![The 60V Solar Limit Is Finally SOLVED [CHEAP FIX]](https://i.ytimg.com/vi/qCgUGNSbtc0/mqdefault.jpg "The 60V Solar Limit Is Finally SOLVED [CHEAP FIX]
The 60V solar limit found on many portable power stations has made it unnecessarily difficult to connect affordable glass solar panels. But these Callsun 275W panels may finally solve that problem. I connected two panels in series, measured approximately 51.1V open circuit, and saw roughly 478W of solar input during 105°F weather.
The pair provides 550W of rated solar for approximately $495.99 before any available discount, while several portable-power-station-branded alternatives cost significantly more for less rated capacity. I also test their partial-shade performance, real-world output, dimensions, weight, construction, and compatibility with high-amperage portable power stations.
