PR1211: BATTERY BANK WITH 11 AH POWER AND included quick release system

The PR1211 with quick release system is the middle member of the Metalsub battery tank series. With 12 Volt and 11 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.

Quick Release System

This type of battery tank is equipped with Metalsub's unique Quick Release system.

This system provides a very compact, streamlined, strong link between the battery tank and the supplied base plate, which is attached to the diving cylinder. The battery tank can be placed or removed with a single press of the button of the resilient locking pin. No tools needed!

The link is incredibly strong, so you do not have to worry about losing or loosening the battery tank. This quick coupling is also made entirely of hard anodized aluminum and stainless steel.

The base plate is provided with thick rubber strips to prevent damage to the diving cylinders and of two types of slots with which it can be attached to the diving cylinder with a standard plastic bottle band or stainless steel clamp band.

Single or double connection

The PR1211 is also optionally available with a dual lamp / charging connection: ideal for underwater filmmakers who like to use two lamp heads to eliminate shadows. If sometimes only one connection is required, then the other connection can easily be closed with a waterproof, flameproof cover.
