Power Consumption Calculation

Use the two tables below to determine the power supply you need to safely and adequately operate your heated garments.


 

Power consumption calculation for combined heating garments to determine the necessary battery capacities of battery packs and battery tanks

Heating products 7,4V - rechargeable battery 11,1V - accumulator 14,8V - accumulator Enter A-value
3-zone shirt - 1,2A 1,6A A
4-zone shirt - 1,8A 2,4A A
6-zone shirt - 2,4A 3,2A A
7-zone shirt - 3,0A 4,0A A
3-zone pants - 1,2A 1,6A A
3-zone pants + calves - 2,4A 3,2A A
4-zone pants - 1,8A 2,4A A
4-zone pants + calves - 3,0A 4,0A A
Overall - 4,2A 5,6A A
Overall + calves - 5,4A 7,2A A
Overall for divers - 5,4A 7,2A A
Overall for divers + calves - 6,6A 8,8A A
Heating vest (up to XL) - 3,7A 4,9A A
Heating vest (from XXL) - 4,9A 6,6A A
Heating vest (for divers) - 5,8A 7,7A A
+ gloves 2,0A 2,6A 3,4A A
+ shoe insoles 0,9A 1,1A 1,5A A
+ socks 0,9A 1,1A 1,5A A
+ socks for divers - 2,4A 3,2A A
+ Knee socks - 2,4A 3,2A A
Total current of all added heating consumers = A
A value x number of hours (planned heating time) = Ah
A = Ampere, the current value for the consumption of single or multiple heating products.
Ah = Ampere-hour, the minimum battery capacity required at 100% heating power.
Example calculation for an 11.1V battery supply:
4-zone shirt + gloves = 4.3A x 2.5h (heating time in hours) = 10.75Ah.
The battery capacity should be at least 10.75Ah for 2.5 hours of heating.
The next larger battery technology would therefore be a battery with 11.1V/12Ah.

Power consumption calculation for combined immersion heaters to determine the necessary battery capacities of accumulator packs and accumulator tanks

Heating products 11,1V - accumulator 14,8V - accumulator Enter A-value
4-zone shirt 1,8A 2,4A A
7-zone shirt 3,0A 4,0A A
4-zone pants 1,8A 2,4A A
Overall for divers 5,4A 7,2A A
Overall for divers + calves 6,6A 8,8A A
Heating vest for divers 5,8A 7,7A A
+ gloves 2,5A 3,3A A
+ diving socks 2,4A 3,2A A
Total current of all added heating consumers = A
A value x number of hours (duration of the planned dive) = Ah

A = Ampere, the current value for the consumption of single or multiple heating products.
Ah = Ampere-hour, the minimum capacity required for the diver's battery at 100% heating power.

Example calculation for a 14.8V battery supply:
Shirt + Socks = 7.3A x 2.5h (heating time in hours) = 18.25Ah.
The battery capacity should be at least 18.25Ah.
The next largest battery technology would therefore be a 14.8V/20Ah battery.
