Rechargeable Li-Ion batteries are amongst the most efficient batteries. They are ideal for the use in marine and offshore technology. They provide the highest capacity while being of low weight and volume. SubCtech produces complete battery packs, the PowerPacks™, in cooperation with manufacturers of high-class and certificated industrial cells. The PowerPacks™ are easy and safe to operate with the matching charging technology SmartCharger™.

Our Li-Ion batteries are used like standard batteries. An electronic circuit provides that the batteries run smoothly. The PowerPacks™ switch off on low tension to prevent damage. The operation disconnects for the time of the defective condition in case of overcurrent or short circuit.

Li-Ion batteries can deliver high current, in contrast to other battery technologies. PowerPacks™ are chosen especially for the marine industry and work much more efficiently than for instance Alkali prime batteries or Ni-Mh batteries, even at very low temperatures.

The PowerPacks™ are offered on different standard configurations. The rugged and corrosion-free housing made of titanium or POM and can be used in depths of up to 6000m.

Connect the battery to the SmartCharger™ and leave it attached until the light signals “green” when fully charged. A special handling is unnecessary. The SmartCharger™ technology enables a safe and gentle charging of the PowerPacks™. The end housing can remain closed during this process. Thus, the packs can even be charged built in or in water.

The Li-Ion batteries are already profitable after the third charging process. They are environmentally friendly. Good operating data of the Li-Ion technology simplify projects and usage. Under rough conditions – such as very low temperatures, high currents (also peaks) or under difficult offshore conditions – our Li-Ion PowerPacks™ provide more power than Alkali primary cells or older storage battery technologies. The easy handling is an important characteristic that makes our PowerPacks™ ideal for usage on board or under extreme conditions like under ice or in the deep ocean.
