When you say $89/kwh, are you talking about just cells, or assembled packs? I’m just about to buy a 5kw Lifepo4 server rack battery from EG4 for a diy project. It’s closer to $220/kwh This is what I’m planning to buy, but you know something better I’d love to take a look. https://signaturesolar.com/eg4-lifepower4-lithium-battery-48...
Do you know if these batteries be used as a replacement for batteries of a lead-acid UPS? I have a Tripp-Lite rack-mount UPS with an extension battery, but its battery has degraded and it can only sustain my computing load for 3-4 hours. It'd be great to replace it with an LFP battery.
I have seen Na-ion replacements for lead-acid, the chemistry is forgiving enough for that. No idea how good are they.
