Our community has rated this post as helpful. If you agree, why not thank dbowmanKY

Before the review, these were easy to find around $1.00 per amp hour, same battery but 40-50% more money after the review. To Me LiFePO4 is LiFePO4, very little difference between the brands, although there is some bad ones out there, most do what they are made for. However when You go premium price, (like this), You better have a top notch battery, trust Me, these are not the best You can buy.

Many like these are used for solar storage, also great for trolling motors, not good for car or truck starting because of the high current draw. They have a Battery management system that will usually prevent them from going over 200 amps at one time.

Like I give a sh!t what you buy lol. Go buy Dumfune (sp) or Humsienk (sp), I'm sure they are cheaper and get your jollies off of them nod Those are great budget batteries if that is what you want.

This is not an impressive price per kWh, but their 314 Ah battery is competitive (without Bluetooth).

Yeah I would agree. Did you purchase the 314Ah battery?

Or better yet, their 48v 100Ah server rack battery is at a low price https://slickdeals.net/f/19012807-wattcycle-48v-100ah-server-rack-lifepo4-battery-630-ac

Im curious how you landed on "LiFePO4 is LiFePO4"? My understanding is BMS, Wiring, build quality, overcurrent, temp cutoffs, etc all matter. I know (or thought) a quality charger matters as well as a bad combo mean 🔥💥.
