In my opinion, that solution is extremely overpriced for what you get. The kit is $700, then you have to buy two of their batteries and you're looking at around $1,400 total. All that for roughly 60Ah of capacity? With AGM batteries, you generally don't want to go beyond 50% depth of discharge...
Seriously, no one is forcing you to buy an EV. If you want to drive in the extreme cold and go on extended road trips all the time, then yes, having an EV as your only vehicle probably isn't the smartest move.
All is I can say is it's really nice not having to worry about stopping for gas every...
I'm still not seeing how the economics of this route makes sense for this type of application. Looking at this model for reference (the most compact version I can find), if I hooked up 2 in parallel, I'd only get roughly 60Ah for $1,400. Compare this to a 105Ah LPO setup, it'd only cost $300...
What are you even talking about? I have an EV, so I can unequivocally say this is completely false.
Winters are pretty mild, not sure what that has to do with anything. If I am stuck in traffic, being in an EV is great. It's nice and quiet and I don't have to burn any gas just to keep my...
Oh, you’re thinking of cylindrical cells. That is one option, but I was planning on using prismatic cells for this build. Same idea, just different form factor:
I just looked this up. While it’s impressive it can output at such a high amperage, it looks like it’s only 30Ah. Probably a decent...
Their website clearly states that since Dakota Lithium is no longer producing the 18Ah batteries, they are putting a pause in selling their battery mount.
I considered the option of utilizing the DV8 storage container but this configuration appears to work for my needs (100Ah capacity) and...
Cool, maybe don't buy an EV then? Or consider all the time you'll save not having to fill up gas every week or so because your EV can charge at home overnight. I'm not even going to address the image you shared due to so many factual inaccuracies.
Thanks for the resources! I've had my eye on SendCutSend for a while but haven't had a good excuse to try them out yet.
This is intended for a DIY project. I've already got a full time job, I'm not really interested in trying to sell this at the moment. Just looking for feedback on the design...
Thanks for the feedback everyone. Giving me some more things to think about.
I'm thinking the BMS will be mounted on the underside of the main enclosure so it'll remain with the cells as one unit. I've never liked the idea of storing a charger or inverter in an inclosed space like the under...
Update: Project is complete. See this comment for final results.

I've been noodling on this idea for several months now, and with how well my portable power station build went, I'm kind of interested in building a proof of concept just for the heck of it. I decided to draw it out to at least...
You could try disconnecting your battery and connecting your terminals directly to the jumper box. That’d be an easy way to test how well it starts the engine when the battery is “dead”. You could also do this multiple times to see how many starts it can do on a single charge.
