Subtronic strobes have non user interchangeable built-in batteries so far. Now, Subtronic introduces a new battery design, allowing the user to disconnect the battery for travel and to exchange batteries between dives. The concept is different from common strobe designs as the battery will come in shape of a strobe arm segment. A new S4 type plug system connects battery and strobe head. This plug system is pretty similar to the already known S6 system, except it features only 4 pins. Those pins have been designed to support higher current strength which is required to supply the strobe with electrical power from the battery.
The battery-arm-segment weight is around 300 grams and capacity is targeted around 1600mAh. Battery charging time is around 1.5 to 2.5 hours. The new battery system will be compatible with Subtronic Mini, Midi and Maxi strobes. Existing strobes can be retrofitted with S4 connection to enable usage of the new battery. A fully charged battery will allow the Maxi strobe to dump ca. 180 full loads. There will be an optional M8 connection accessory to allow the battery-arm-segment to be used with foreign strobe arm systems.
This new battery design intends to make airplane travel with Subtronic strobes easier as batteries can be fully disconnected from strobe heads. Furthermore, batteries can be changed between dives.
