Ammonite Accu Thermo 24 Special

Ammonite Accu Thermo 24 Special

The Ammonite Accu Thermo 24 Special battery is a 200m depth-rated version of the Accu Thermo 24 designed explicitly as a heating system battery which you can use with any Ammonite primary light head whilst operating a Santi Heated Vest, Heated Undersuit or Santi Heated Gloves.

It operates at 12V with up to 200W heating power and 2-stage power control.

Modern power supply source

Simplicity, intuitive operation and performance reliability; up to 200 Watts heating power. The charging port of Accu Thermo 24 Special can optionally be used to connect any of the Ammonite dive light heads. The charging port cannot be used with heating systems.

Advanced functions of Accu Thermo 24 Special

LED Indicator provides information on the battery status and charge level. Intelligent E/O "knows" when the cable is disconnected, when to cut off voltage, and when to bring back the power supply after reconnecting.

Easy switch and effective adjustment

Two-stage power control means effective power management, extending battery life. The magnetic switch position change is easy to feel, even when wearing thick diving gloves.

The compact-size casing is made of high-grade aluminium coated with hard anode, while the device is sealed with two o-rings and equipped with a safety valve.

Additional protection and status signalling

The inner microchip system signals a low battery level with a strobe flash and automatically switches to backup mode (light output at 20% light intensity) when the battery is drained.

Maximum operating times:

• Heated Gloves 8hrs 50min
• Heated Vest 4hrs 25min
• Heated Vest + Gloves 2hrs 50min
• Heated Undersuit 2hrs 10min
• Heated Undersuit + Gloves 1hr 45min
