View product information of Battery tank FX1210



The FX1210 with a fixed mounting plate is the middle member of the Metalsub battery tank series. With12 Volt and 10 Ah power it provides a very long burning time (at full power) of more than 4,5 hours when using a 24 Watt lamp head and up to 2 hours when using the most powerful Metalsub cable lamp of 60 Watt. This battery tank is a nice compromise between compactness and large capacity.


Despite the compact dimensions of this battery tank, it’s a full member of the Metalsub family:

  • Manufactured from a very high quality aluminum.
  • Equipped with Metalsub's unique anodising layer, according to US Military Standards (MIL-A-8625-E type3 class2). This protective layer is also impregnated with Teflon, which guarantees a high degree of corrosion resistance.
  • Equipped with an overpressure valve, so that any gases which arise during charging can safely leave the battery.
  • Designed according to the "less is more" principle: no unnecessary buttons, lids or openings.
  • The battery tank has only one connection that is used both to connect the (exchangeable) lamp head and to charge the lamp.
  • The streamlined, rounded, minimalist design without sharp edges also ensures that underwater lines and nets do not easily catch on this tank.
  • Equipped with Metalsub's very robust cable light coupling: connect or remove in seconds with just a quarter turn.
