SPECIFICATION
Specification
CHOOSE YOUR ARMOR: STANDARD VS. SPECIAL
Selecting the right housing for your exploration style.
Aluminum performance or polymer agility?
While both models share the same advanced electronic heart and 281 Wh capacity, the choice between them comes down to your environment. The TYPE 24 SPECIAL is not higher-capacity than TYPE 24 — it is reinforced for greater depth.
- ACCU THERMO 24 (Polymer Agility)
Features a lightweight and durable Delrin® (polymer) and aluminum housing. Ideal for travel and streamlining gear, with an operational depth rating of 100 m. - ACCU THERMO 24 SPECIAL (Aluminum Armor)
Built with a full hard-anodized aluminum body for extreme mechanical resistance in tight caves or wrecks. Specifically reinforced for extreme exploration with a depth rating of 200 m. - Buoyancy & Weight
The aluminum SPECIAL is heavier on land (1400 g) but actually lighter in the water (600 g) compared to the polymer version (710 g), which assists in perfecting underwater trim. - Shared Technology
Both units feature the same 3-stage power control, LED charge indicators, intelligent E/O protection, and essential safety valve.
Dual-Purpose Power Hub
The ultimate energy source for extended cold-water missions.
Simultaneous Light and Heating Control
The ACCU THERMO TYPE 24 SPECIAL is specifically engineered to manage two critical systems at once. Unlike standard batteries, it features a specialized electronics suite designed to power both your high-output light head and your drysuit heating system.
- Two-Step Switching: Equipped with a dedicated magnetic switch that allows you to manage power delivery independently, ensuring your light remains steady while your heating is active.
- Intelligent Heat Management: The internal electronics are optimized to handle the high current draw of heating vests and gloves without compromising the performance of your primary light.
- Voltage Stability: Provides consistent power output to both connected devices, ensuring reliable warmth and visibility throughout the entire dive.
Military-Grade "Special" Construction
The ultimate energy source for extended cold-water missions.
Built to survive the most punishing underwater environments.
The "Special" designation means this canister is built to a higher standard of physical resilience. It is designed for explorers who push their gear to the absolute limit in caves, wrecks, and deep-sea conditions.
- Hard-Anodized Armor: The housing is crafted from a specialized aluminum alloy with a thick hard-anodized layer for maximum scratch and corrosion resistance.
- Shock-Resistant Delrin®: Both the top and bottom caps are machined from high-density Delrin®, providing superior impact protection and thermal insulation.
- Deep-Water Integrity: Featuring a reinforced double O-ring sealing system, the canister is pressure-tested and certified for safe operation at depths of up to 200 meters.
Operation & Power Management
Precision control for extended missions.
Three-Stage Power Adjustment
The ACCU THERMO 24 SPECIAL features an advanced power control system designed to maximize efficiency and comfort in cold water.
- Effective Energy Management: The system offers three-stage power control (0%, 70%, 100%), allowing you to manage energy consumption and extend battery life.
- Tactile Magnetic Switch: Power is regulated by a large magnetic switch featuring a distinct, mechanical step that is easily noticeable, even when wearing thick diving gloves.
- Simplified Control: The intuitive design ensures that adjusting your thermal comfort and lighting is seamless, regardless of the diving conditions.
Intelligent LED Monitoring
Stay informed with the integrated LED indicator..
Real-Time System Feedback
The LED indicator is located on the top cover of the battery, providing critical information about the charge level and the operating status of the entire system.
- Battery Charge Level: Upon activation, the indicator lights up for 4 seconds to show the current capacity: Green steady (75%-100%), Green blinking (50%-75%), Red blinking (25%-50%), or Red steady (less than 25%).
- System Readiness: After the initial charge check, the LED switches to indicate the connection status: two red flashes followed by one green flash means the battery is ready, but the E/O receiver is not yet connected.
- Active Connection: Once a receiver is detected, the E/O circuit becomes active, and a steady green light confirms the system is functioning properly and supplying power.
Flagship Protection & Safety
Advanced safety features for peace of mind.
Engineered for Reliability
This flagship model is built with multiple layers of protection to ensure both the equipment and the diver are safe under extreme pressure.
- Safety Valve: The canister is equipped with a safety valve that protects the battery from internal pressure buildup, which is essential during transport and altitude changes.
- Advanced BMS: An integrated Battery Management System (BMS) protects the high-capacity Li-Ion cells from over-charging, deep discharge, and short circuits.
- Rugged Construction: Made from hard-anodized aluminum with Delrin® caps, the "Special" version is pressure-tested for depths up to 200 meters.
- Secure Attachment: In its standard version, the battery is fitted with a fixed webbing loop for stable mounting on a 50mm hip belt.
MODULARITY & COMPATIBILITY
Versatile power for any mission.
The Heart of a Modular System
The ACCU THERMO 24 SPECIAL is not just a battery; it is a central hub designed to be part of an interchangeable and fully compatible diving system. This modular approach ensures your equipment remains adaptable as your diving needs evolve.
- Universal Connection Standard: The battery is equipped with a standard chinch-type connector for lighting and an E/O cord for heating, making it compatible with all Ammonite System light heads and heated dive wear.
- Independent Power Management: Thanks to the modular design, you can easily swap light heads or change cables in the field without needing to replace the entire power source.
- System Growth: Start with a single light head and expand your setup by adding heated vests or gloves, all powered by the same reliable ACCU THERMO 24 SPECIAL unit.
- Reliability Through Simplicity: The modular components allow for quick maintenance and easy configuration changes between dives, whether you are in a cave, on a wreck, or in open water.
