I have the HQST that is in the second link you posted but mine is the 40amp. I didn't get the optional bluetooth adapter for mine. It uses the BT-2. I just have that external plug in screen which is handy. This unit is made by SRNE. Working great for the past two and half years. They sell...

The Ecoflow River Max is okay for what it is. 600 watts inverter, 200 watts solar input. It is fine for light loads. The 200 watt solar input is what I would say is holding it back. So can't charge/passthrough enough if I am running bigger loads. To be honest I have never been able to get...

Those are really nice. Pure sine wave inverter from what I remember. Too bad the batteries don't seem to last for me.

I have a bunch when I started playing with solar. 5 X Rockpals 300W - These were cheap on Ebay being sold for parts that I pieced together to make good working units. The BMS is the Achilles heel for these. Replace the BMS and unit works perfectly again. 2 X Ecoflow Delta 1 X Ecoflow River...

Jackery is popular but is behind the times now days. The solar/charging input is just too low as in how many watts it can take. Bluetti is good. AC200P will fit your use case scenario as it is LifePO4 and will have an inverter powerful enough for what you need. Ecoflow you aren't going to...

The "River Pro" only has a 600 watt inverter so that is the limiting factor. It has a boost function that basically lowers the AC voltage going out to trick your higher power devices in working albeit at a slower pace. Using that feature you can have it run a coffeemaker but don't believe it...

Make sure there is not a big voltage difference between cells in each board before putting them together. The PCB's themselves have a trace fuse for each cell and also a 5 amp fuse for the board. A big difference between boards will blow those. Difference between boards will cause an influx...

I am currently experimenting with a setup similar. I have a Dell (APC) UPS that used three 12V SLA batteries in series. The connector going from the batteries into the UPS itself is a powerpole connector. There is also a EBM connection on the back for external batteries. I have connected...

My go to place for 18650's will be "Cell Saviors". There you can get whole pack, cells that are broken down from the packs but not tested and also cells that have been run through the tests with the capacity labeled on each one. I have had very good experiences with them and their service is...

Those look like the standard JST XH. I have noticed that some BMS have a variation of them though. Same look but little smaller size.

The 5521 bullet connectors I usually see show that they will handle 5 amps max. Make sure the connector used will handle the amps that will be drawn.

I think the same thing is happening to me right now. I made two purchases at Battery Clearing House on the same day. 11/10/2021. Get an email showing both were shipped out. Well.... Two days later I received the second order but not the first. I contacted Battery Clearing House and they...

Just saw this post.... Wonder if the same thing happened...

The strangest conversation just happened between FedEx and I. Here is the background.... I ordered some modem packs from Battery Clearing House. The package never showed up. Battery Clearing House told me they will reach out to FedEx to file a claim. One day later.... (Just now) FedEx...

Interesting.... So in the video it does have four packs of 20 cells each. So not the series of the cells and then parallel that was said before.
