This community seems not to do a lot of tweaking, so here I come.

I already have an Ecoflow Delta 2 power station with an open 52V port (the famous 1kohm resistor hack). That allows me to connect a 48V-to-12V converter and run things like two refrigerators and a diesel heater at the same time. Around 15-18A instead of the official 10A which would otherwise shut down the power station.

But I got a great ebay deal on a new Extra Battery so I bought one to double my capacity. Unfortunately the 1kohm hack doesn't work with the Extra Battery and the BMS circuit board doesn't have any permanently awake sections. You can either bypass the BMS (bad idea) or try to figure something out.

In my case after long hours with the multimeter, I've decided to give up and simply buy another BMS and connect it alongside the original one. Both BMSs are invisible to each other, which is great, and the additional BMS lets me use the battery separately from it being woken up by the Delta 2. From the engineering standpoint, that's perfectly fine. I simply also want to run many 12V items off the Extra Battery with the help of the 48-->12V converter.

What you can see in the photos are the following things...

1. The original BMS has 8 pads from each cell on the top side and 8 pads on the bottom side. Fortunately they are labeled. One side has odd numbers B1, B3, B5 etc. the other side has even numbers B0, B2, B4, B6 etc. This makes connecting the balance wires absolutely easy.
2. I used a Lifepo4 Daly BMS with a limit of 60A. Drawing 30A at 12V is only around 8A at 48V so I have plenty of headroom which I don't need anyway. The BMS was around $25
3. HUGE THANKS AND BLESSINGS TO THE ECOFLOW TEAM IF THEY READ THIS. Many modern companies are very mean because they install traps that make any tweaks impossible. Some BMSs lock up permanently once disconnected, some lock up when an unknown power source is connected, some use complicated communication protocols to make any tweaks impossible etc. Ecoflow is a great company because the products are made with the highest quality but at the same time are user friendly. If you disconnect the BMS from the battery it will work. If you solder things, it will work too. If you do the famous resistor hack, everything will be fine. Big, big thanks to Ecoflow for not being assholes. I really appreciate it.
4. There is plenty of space inside for the additional BMS, the converter and some fuses, switches etc. which is great.
5. I 3D printed a back plate with holes for ports and a switch in order not to damage the original one and I have a 12V/30A outlet, an inlet (58.4V max) which also outputs 52V, a switch that turns the converter on. I like the clean looks.

Now, my Delta 2 accepts solar panel charge through the XT60 port and charges both batteries. The Extra Battery accepts charge (58v) from my DC-DC charger and also has the converter (XT60 in the upper left corner) as an output for my 12V appliances. Both batteries share the charging, discharging power because they are connected with the original, non-modified cable. Super cool.

I just bought a used (and old) DNP DS80 printer in order to be able to print up to 8x12in.

This is the result of years of lost fights against inkjet printers:

- whenever I want to print after a long break I need to clean the heads.

- when I clean the heads it turns out they are either leaking a bit or not all the nozzles are printing

- by the time I make one successful print, I have already wasted half of my ink capacity on trials and errors

- somehow the prints are always far from what my screen shows, even after calibration. Always a lot of tweaking.

The result is a high price per print and a lot of wasted time and life.

The DNP DS80, although older than maybe some of the persons reading this post, gives absolutely wonderful, brilliant, astonishing results. An 8x12in print is $1 or a bit less, which is great.

It's not my first thermal sublimation print but I clap my hands like a toddler each time I see the results. They are just like traditional photo prints: continuous gradients, no raster, vibrant colors etc. I can also make one print today and make another print 4 years from now. No inks to worry about, no printhead alignment, no clogged nozzles. Just turn it on today or in 2033 and make as many prints as you want.
OMG, I am so happy

Yes, 8x12in is not a big format but nice enough for most household needs or for most customers.

Hi. I have this "Ecoflow Delta 2 Extra Battery". I would like to wake up the mosfets in the BMS in order to have any power at all, either from the XT150 socket or the P+ and P- pads on the board.

I know that the 1kohm resistor works for the power stations but I don't know what wakes up the extra battery.

I want to install a 48V to 12V step down converter in this battery and also an XLR port to recharge it with a 58V charger. That's all I need but I need to wake up this board.
