edit: this link seems to bring me to a different, larger form factor battery. fix link to the correct one?

edit2: scratch that, further down the page they advise that the original "310 ah" version is done and that the mini 314ah will be the one shipped. cool

Wow, how they heck are they packing this capacity into that housing. Impressive

I have a smaller humsienk lifepo4 battery I've been pretty happy with

Not that hard, they're basically just lining up the cells in a tight configuration. This thing will weigh a ton though.

I'm in the market for one of these high capacity mini batteries for my camper. Since I plan on using it year round I've been searching for a heated battery. Anyone have any recommendations on how to heat this one from it own power? Most heaters I find are 120 volt

I would be careful ordering from this company. Their product descriptions are misleading. They will more than not likely ship the battery you are expecting. They previously posted a similar misleading sale for the 300ah and free upgrade to 314ah but shipped the 300ah batteries. See this previous deal https://slickdeals.net/f/19164070-humsienk-12v-314ah-upgraded-lifepo4-battery-f-s-237

I'm getting a sales tax of $39.31 at checkout which is close to 15%. My state has a sales tax of 9.9%. Anyone else seeing this anomaly or can explain why it's higher?

Any 12v 314ah battery is going to weigh a ton. And these smaller sizes aren't achieved by lining up the cells. The prismatic cells in all these batteries, big or small are all stacked in the same side by side configuration. It has more to do with everything other than the cells, like better cable management, more compact BMS, less internal bracing, etc, etc..

It says on the ad it will be upgraded to the mini but I don't see anywhere during checkout does it indicate I'll be getting the mini or bluetooth model. I wish they did more to ensure me that I'll be getting the smart mini w/bluetooth model.

I thought that screenshots would help when I ordered the last deal. I did not get the upgraded battery, other slickdealers also mentioned they did not get the upgrade. I assume their 'typos' are intentional on the upgrade graphic on the site. If you look at the details the numbers are slightly off. It shows a capacity of 3840 (which is a 300ah not a 310ah), not 3968 like the picture shows and 313ah not 314ah on the mini version. Good Luck.
