True. But read further down in the "Feature" section (see pic).

The 20A discharge is from the CHARGING PORT CONNECTION so not from those fancy gold plated battery terminals which would be 1C discharge.When they say different things withing 3 sentences ...... I would consider it a VERY high risk purchase.
Bob B:, You're correct. The discharge rating is on the "Golden Terminals"...you're on the right track. Each type of battery has a discharge rating. My SOK batteries (what precipitated this part of the conversation) has a 100A max discharge rate each. It states it clearly on the side of the battery. This info can be critical, because if you draw more than what the battery can discharge (rated) either the BMS will shutdown (or melt), or the wires inside will melt. Either one is not good. IMHO, higher the discharge rate is an inherent safety factor. But, then again, one pays for these features/capabilities. One of the reasons why I'm moving up to a more capable battery like the KiloVault which has a 150A charge and discharge rating...but I'll be shelling out more dough. SOK battery is good to learn on and can be applied in wide production applications. I'm running my home office off of the two batteries without using Shore Power (recharging them using solar), but I haven't tested my vacuum cleaner on it yet which will draw a lot of amps. I need a bigger inverter before testing.I guess I've never seen a rating that was for discharge ... on the charging port. Just seems .... Illogical.
Did you logically look at the pic of the battery on Amazon?I guess I've never seen a rating that was for discharge ... on the charging port. Just seems .... Illogical.
I'm not entirely convinced these features are "unusual". My Rockpal 500 watt battery has all those features, except that it doesn't have terminals...but does have a cigarette adaptor. IMHO, it looks to me they took a battery box, added some cells, a usb port, and terminals, plus provided a adaptor to charge. I built one that is fundamentally the same. It doesn't have a 20A discharge rating, and it looks funny...but strangely enough I can run my home office (including my 75" flat screen) for about 10 hours from these little jewels. . Do you see the USB adaptor? It's has a PD port and 3.0. I also can carry these batteries around since the cases have a sturdy handle. What is nice is that these batteries fit perfectly inside the cheap Harbor Freight cases ($12 each).Did you logically look at the pic of the battery on Amazon?
It has the unusual feature of a charging port on the end of the battery and USB plugs.
Also has the usual battery terminals on top that are 1C or 100Ah discharge rated.
That is too bad, I have 6 I hoped this would be a case that would hold all of them.@Michael S I went with the same case @David Smelser recommended. Works perfectly for 4, but just a hair (1/8” or less) too small to add 5th/6th batteries.
