Just bought a pallet of these to replace a 20 year old industrial battery bank of twelve industrial 2 volt 1460 AH VR AGM cells going on their 25th year! With a commercial desulfater attached! I'd like to see lithium attempt this! 😂 Lithium would absolutely FAIL under the -21 °F winter conditions that these batteries will go through. PLC AGM would survive a EMP or MCE far better than a BMS on a LiPo4 battery.... Cheers!
I’d gladly use AGM or PCC but between higher cost per kW than LiFePO4. The next biggest issue is just how heavy they are vs LiFePO4. With new Na Ion (sodium) batteries about to hit main stream markets. It makes an even tougher case against lead.
@@THEOFFGRIDMOUNTAINHOMESTEAD Where is the heat energy going to come from in an off-grid system? Particularly for enviromental monitoring/telecom were it's not powering an inhabited structure. Even if it's technically worth it to enclose and heat the batteries, it increases the complexity and part count of the system and increases potential points of failure. And batteries that include heaters get expensive.
Um… Inverters and electronics give off heat. Example: cell tower stations need Air Conditioning even in winter. Otherwise one could implement some of 👇 Closed cell foam insulation DC heaters DC mini splits Gas fired heaters Liquid Fuel heaters etc etc even AGM/PCC/FLA still suck and lose capacity etc in cold temps. Internally heated lifepo4 is still cheaper than lead based batteries of same kWh, charge controllers can monitor temps etc all kind of low temp workarounds
ATL E is out of business and no longer sell these batteries. I own two and frankly I am not impressed with AGM batteries at all. My lead acid and LiFEPO4 work better for high amperage use.
Anybody that needs to charge below freezing, or whose application will see calendar ageing outweigh cycle ageing as a cause of failure. Additionally no need for a complex BMS, and is compatible with a wide range of off the shelf chargers and accessories.
