I meant to be adding to this thread but have been busy with other things. Anyway, I ordered 16x 280's from Jenny out of China on May 26th and received them July 6th and 7th. They all look really nice (no bulging, dings, or dents) and are the same voltage (3.33). I wish I had asked to buy some...

I thought lithium ion batteries were limited by watts or watt/hours per box to comply with shipping regulations or something like that. That might have been just for lithium polymer though and could have changed by now.

Looks like the Docan site is down, or gone rather? All I am getting is 502 error. I swear I just looked at batteries there a couple days ago. Anyone else having this error? https://www.docanpower.com/

Regarding a case for your build, if you were to get the 100ah cells linked in post #10 by Jim, 16 would fit in this milk crate. The crate measures 12x18 internally while the pack would measure 11.4x15.4. You would have to sawzall the top off as it is a bit high at 11" and said you have 9". The...

Another way to go about it is to look on alibaba for what you want and then contact supplier and request a quote for door to door pricing (DDP) to your location. The prices are regularly better than aliexpress. By the way, what are the dimensions of the battery compartment?

Great point. I had forgotten that some of the pre-builts do not handle being wired in series. I'm also in complete agreement with the rest of what you said. Edit to add: 16x280's in the above configuration would measure 23"x14"x9 high if you are wondering if it would fit in the amount of space...

That 280 peak is only for 5 seconds so if you pull over 100 amps going up a hill, you might not make it all the way to the top. That said, I believe you took some readings and came to the conclusion you wouldn't be pulling over 100 anyway even up hill. Worst case scenario is you do not mow on...

First you are going to want to know the size of the cells you choose, then determine how many you will group together, then find/make a box that size. For instance, here is an image of 16x 135ah cells in an 8x2 configuration. This layout measures 13.5" wide and 15.125" long, and 7.25 high (plus...

You are saying a lp furnace that "uses the least power". I'm assuming you mean electric power? Have you looked for one that operates with a thermocouple? After the pilot is lit, the heat creates the electric power needed to turn the gas on and off and is self regulating using a thermostat on the...

That's true and I am in the same line waiting. He did however mention purchasing quite a few 150ah's that were ready for immediate shipping if I remember correctly. That's probably the direction I would look first before buying through Ali. Like I said before, if the output works, 16 could fit...

Good day. It appears those batteries you linked to will be able to replace the agm's in your mower. I would expect you can also use your charger without issue. Thoughts; You do not have to match the amp hours, only the voltage. The size difference between the agm's and lifepo4 might make it so...

I bought them from Amazon in 2019. The one you are seeing is the current production and I doubt you'll be able to find the same 10 pound ones. I'm wondering if they have strengthened them or added a better coating or something that added weight. I wouldn't hesitate to buy them.

Yes, that is the same as the label on my panels. I have not actually weighed a panel but they are light and I believe the 10 pound claim. If they are saying the current batch is 12 lbs, I would believe that too. As often as the specs change, it seems like they just build these with whatever bulk...

For size, I was referring to footprint, but I do that with the assumption that the rated output would align with the size. So far, the smallest I have found is this one. I would like something more along the lines of this size. I just don't know if something like this exists for LTO cells or if...
