Why is it so expensive? Just an extra XT60?

There are just too many options available for 100Ah batteries, which provide 100% more power than this for only about 25 to 35% more money. In my opinion, the built-in XT60 interface is just not worth the extra dinero. Especially considering you can buy a handful of xt60 pigtails on Amazon for 5 to 10 bucks. Sure it wont be as pretty, but you also won't be limited to 30 amps if you added a connector yourself. Many things to consider but I'll pass on paying that much extra for a built-in XT60 cable. I'd much rather buy me a 100ah and buy connectors if I really needed xt60 plugs all for just a few dollars more than this.

I'm thinking the same thing. XT60 pigtails are a dime a dozen... well a couple bucks but still. If you shop for a sale, you can buy a 100ah battery for just a little more than the price of this.

Also buy 2 get one 50% which makes the deal better for 100Ah.

I don't get it.. exactly... It's an xt60 charging port? is it just connected to the same positive and negative terminals?

could you plug a solar panel directly into it and charge the battery with just a solar panel, or do you still need a solar controller?
If so, that would be a huge advantage of having the XT60 plug. Otherwise, don't see the point.

I appreciate eco-worthy's attempts at creating niche versions of all their products. Lots of options for a variety of use cases.

the 100amp has been less than that price this year

an XT60 cable is less than $10

This is a hobbiest battery, think video cams, drones,etc. A 100AH size and weight can be overkill in some use cases.

Technically, a small panel that meets the voltage specs of the BMS *could* charge this, some suitcase/folding panels even have xt60 in their output connector kits. But this battery is so small it is much faster and convenient to charge with a lifepo4 charge adapter, and better for the cells' health over time as it reaches 100% state of charge to balance cells.

Many portable solar panels have XT60 connectors but the reason being is xt60 connectors have become the go-to or near standard input on so called "solar" generators if you will, but the important thing t note is these generators all have built in solar charge controllers. Directly connecting a raw solar panel to a battery without a charge controller is a very bad idea. There's huge voltage & current swings with the incoming photovoltaic current coming from a solar panel. Not to mention lack of any type of regulation and can overcharge & damage the actual BMS. BMSs are not designed to regulate PV electricity for charging. Solar charge controllers exist for very important reasons. Literally nobody that understands this stuff will tell you its ok to connect a solar panel directly to a battery. Don't do it. Don't take my word for it. Go to any solar forums and ask around but be prepared to be laughed at if you ask that question. Here. https://www.mobile-solarpower.com/ This is Will Prowse's website. He's widely considered to be one of the top experts when it comes to solar. He knows his shit. I've learned so much from him. heres a more direct link to his forums. https://diysolarforum.com/

Not directly. It says in the specs its port is limited to 30 amps in/out so thats actually only half the rated continuous current than an XT60 plug is designed to safely handle for long periods of use. which is you guessed it... 60 amps. Keep in mind that's a continuous 60 amps because XT60 connectors can easily handle double (120) or even more of its rated amperage as long as it's not continuous. It being limited to 30 amps will be fine for most, but it definitely limits its full potential/capability.

The smaller portable panels I had in mind contain a SCC interface built into the unit: eg:
https://www.amazon.com/ZOUPW-Port...B0CR42CFJ9

https://www.amazon.com/SUNAPEX-Ma...T1zcF9hdGY


edit: and now you mentioned the xt60 and power stations, which also means this battery is ready to plug into most power stations for instant added capacity (for the user confused on why it would have an xt60).

yeah I agree with this. I have an application where I am trying to conserve weight. 50aH is enough. 100aH is a little bit overkill, but it's an additional 10lbs for 50ah.

I bought the 50aH non-bluetooth Eco Worthy this week for $100 shipped. I wish I had waited.

I went to the product you linked. I asked if you can connect it directly to a battery. it said this. No, if you want to charge a 12V battery using this solar panel, you will need to add a MPPT/PWM charge controller, which is not included with the product. Which is exactly what I said

The second product clearly says it has a built-in solar charge controller so thats great. So, what part of you need a solar charge controller don't you understand?

So about connecting a 12v battery directly to a solar gen. This can be accomplished by simply adding a 3 dollar XT60 pigtail to it but keep in mind, If you use it this way for a solar gen, you are limited to a slow as molasses charge rate of about 120 watts (because solar gens are limited to 10amps on there dc input) so its a far cry from instant additional capacity. But yes you can certainly do that. Better to get a device that ups the 12 volts to at least 24 but preferable 48. By doing this, you can tie directly into the solar input on a solar gen and get hundreds, even a thousand watts of charging power on solar gens that can handle that much solar. Most modern ones can handle 5 or 600 watts of solar input so that's still 500% to 600% faster than plugging in a 12v battery directly.
