The ALM 12V7s HP (HIGH POWER — up to 45 A continuous charge/discharge) is the next generation of NEC Energy Solutions pioneering Advanced Lithium Module, now with integrated protection for short circuits, over and under-voltage, temperature, charge and discharge add to the inherent Nanophosphate® cell safety. Consistent energy capacity, even under high discharge and deep cycling, allows system right-sizing, while arrays up to 48 V and 2.6 kWh extend application flexibility.

If your end use application is unlikely to see charge/discharge currents above 23A, consider purchasing the ALM12V7s (standard) version. The only difference between the high power and standard versions is the quantity of power electronics to support higher current levels. All other specifications are identical (amp-hours, watt-hours, voltage)

ALM 12V7s Applications


  • Base stations, broadband nodes
  • Long cycle and float life supports stable or unstable grid applications
  • Low weight eases pole-top utilization

Uninterruptible Power Supplies are ubiquitous not only in data centers and small offices, but also in a broad array of industrial applications – anywhere where computers are used in critical applications. The exceptional power delivery capabilities, long life, and light weight ALM 12V7s enable UPS systems including:

  • Industrial Automation, Server UPS

Off-grid power systems demand fast and frequent charge and discharge cycles, often in harsh environments with portability requirements. The ALM 12V7s’ long cycle life, fast charging, and light weight are ideal for these challenging applications:

  • Oil / gas / mining, remote sensors, electronic road signs, lighting

Most applications have a combination of frequent and deep charge/discharge cycles and harsh environmental conditions. The ALM 12V7s offers consistent power delivery across state- of-charge, fast recharging, light weight, long life, and robust safety. Such applications include:

  • Autonomous robots, Industrial machinery
  • Security systems, Emergency lighting

Medical equipment increasingly relies on advanced batteries for operational portability. However, sidelining equipment for hours to accommodate battery charging or frequent servicing directly impacts the cost and quality of patient care. The fast recharging and long operating life of the ALM 12V7s maximizes the value for:

  • Mobile Carts, Diagnostic Equipment
The ALM12V7s is available with nominal and high power (HP) models to match application requirements. The ALM 12V7s EverSafeTM battery technology provides protection against operation under many unsafe conditions such as over voltage, under voltage, over temperature and short circuit.
