Moisture and salt resistance
The marine environment is damp and salt-laden, so the structure and protection are assessed against salt spray and moisture.
Marine battery packs: auxiliary power and starting
Yacht auxiliary power, marine starting batteries and navigation backup must work reliably in damp, salt-spray conditions. Moisture and salt resistance, high capacity and safety redundancy are the three requirements.
Requirements
What this application demands of the pack
These are the electrical and mechanical points that matter in this application.
High capacity and power output
Auxiliary power and starting need high capacity and large instantaneous current, so capacity and rate follow your loads.
Safety redundancy
Waterborne equipment demands high safety redundancy, so the protection strategy and structural reliability are settled at the design stage.

Checklist
What we need from you
Give us these and while meeting your performance needs we pick the most cost-effective option for you.
| Item | What to tell us |
|---|---|
| Equipment type and use | Auxiliary power / starting battery / navigation backup / USV / outboard / rescue equipment |
| System voltage and capacity | System voltage and required capacity |
| Starting and peak current | Starting current and peak current requirements |
| Installation environment | Inside or outside the cabin, salt-spray and temperature conditions |
| Certification requirements | Target market and the certification items needed |
| Capacity & discharge | Built from 0.1 Ah to 600 Ah to your requirement — common levels such as 10 Ah, 20 Ah, 50 Ah, 100 Ah and 200 Ah are all confirmed per model; continuous and peak rates are matched to the duty cycle |
The above describes the general matching logic only. The final selection is made by us — your requirements come first, and we work to reduce your cost as far as safety allows.
FAQ
Questions about marine packs
Which chemistry is used for marine packs?
Usually assessed from the LFP direction, which suits long-life marine auxiliary and backup applications in terms of cycle performance and thermal stability. The final choice is ours to make based on your requirement — lithium-ion or solid-state, we match the more suitable option.
Can it cope with salt-spray conditions?
Tell us your mounting position and the salt-spray conditions, and we will assess from the structure and protection direction, working with the unit to meet the moisture and salt resistance targets.
Can it be built to our starting current?
Yes. Tell us your starting current, peak current and system voltage, and we will match the model and protection parameters and complete the series/parallel design.
How is certification handled?
We hold 17 certifications and reports including CE, IEC 62133, UL 2054, RoHS and REACH. Mature models come with existing certificates, provided directly; newly customised models are checked item by item against your target market and specifications. New certifications are handled end to end by our team, with testing costs and timelines set out in the proposal for your confirmation before anything starts.
