ETL Listed to UL 1741, NEC compliant
Our lithium ion batteries are LiFePO4 Lithium, iron, and phosphate.
Our LiFePO4 energy systems are non corrosive, non gassing and non flammable. These battery systems are the safest batteries in the world. Virtually no maintenance other than monitoring. Systems include Master BMS and numerous slave BMS depending on Li system size and capacity. All API LiFePO4 energy systems have a programmable low voltage disconnect system that protects the batteries from complete discharge. We also have a high voltage protection system. Our latest generation, generation 11, incorporates our proprietary BMS system(s). Over a year in the making for R&D, engineering, prototyping, testing, and manufacturing. We are now manufacturing our own proprietary API BMS. State of the art, 15-62 vdc (no more power supplies needed), plus CAN and trigger ports. Our new API BMS incorporates our proprietary, totally unique, cell balancing system. No other BMS in the world can do what we do. We can control solar, wind, hydro, generators and/or loads if needed.
BMS remote monitoring system for the API LiFePO4 48 VDC nominal systems.
Our API lead acid batteries are industrial grade, rated at 1300 cycles at 50% DOD. Close to 20 years life is not uncommon at 20% DOD. We recommend cycling lead acid batteries 20% DOD. This keeps the battery at its highest efficiency and many times we can get close to 20 years of usage. Plus at a normal 20% DOD you have plenty of reserve power for emergencies should your backup charging system have issues or problems. All our API lead acid batteries include single point watering systems. Single point watering systems simplify the once a month maintenance required for proper lead acid battery performance. Just plug in the watering system, turn it on and it fills the individual cells to the desired level. There are electrolyte level indicators on each filler cap that indicates the level of electrolyte and tells you when the cell is full. Once all cells are full simply turn off and unplug and you're ready for another month of trouble free power.
Usually free freight to U.S. Industrial grade 2 volt cells. Either in individual cans or one big can for all cells. Individual cans per cell are more expensive but easier to move. A big can may require a forklift to move. These batteries are rated at the 20 hour rate. 5 year warranty. #2 connections required. Too many configurations to quote so call us at 707-485-0588 or e-mail us if you don’t see what you want. All Hawker batteries come with a 5 year pro-rated warranty.
