Lithium 12 volt battery Is there a clear leader?

Sounds something like a Goal Zero type power pack minus the remote control 10 watt flood light.


Clicky

I would have to have a ten pound battery. It's all about a herniated spine :(

David ... what do you want ... ??

1. Cheapest but DIY messing around?
OR
2. Plug and play and then spend your saved time doing other things?

Here's one plug and play model I would choose if I could sell enough stuff on craigslist to afford it and wait until it was restocked: https://starkpower.com/product/12-volt-125ah-battery/

Why are they out of stock?

I would only use one with a removable and serviceable BMS. One that can be serviced in the USA. Sending a non serviceable battery to China for repair at those prices is not worth the chance and they are not going to just dish out new $1000 batteries because you think you have a problem with it. Many don't even have serviceable BMS.

For that price difference between battleborn and the cdn unit--it would pay for a trip to pick it up. Have a holiday!

In my earlier post, I was not talking about LiFe batteries. I'm not a fan of that chemistry, and either is Tesla. If I recall correctly, they use regular 'ol LiCo right now but are looking at switching to NMC down the road.

Would I tell someone unskilled to build a big LiCo battery for their projects, no.

Just because it's home made doesn't mean it can't be "dropped in" ... The only reason the LiFe are drop in is because A) they're underpowered from what they could be and B) the manuf is relying on the chemistry to tolerate abuse from a lead acid charging system

Check out Jehu Garcia on the YouTubes... he's no rocket surgeon but that doesn't stop him from building his own LiCo Powerwalls. It doesn't hurt that he owns a battery recycling company, so he has a lot better access to cells to cherry pick from.
