Some key guidence
Many upgraded power delivery systems currently use Lithium, and specifically LiFePO4 technology. Due to its stability vs density it is now the go-to for high performance marine energy storage. However, there are some things to be aware of - safety is critical.
Be sure that:
- The battery management system (BMS) is designed to operate with the chosen battery and connected devices are compatible. This protects the batteries from overheating and is the single most critical piece of equipment to consider
- Cooling in your situation is adequate (both the electric motor and the control systems)
- Warranties are in place, i.e. build quality is guaranteed
- Your insurers are content with your installation
Online you can find plenty of advice on DIY options, including cheap sources of lithium ion batteries. But.....
Please don’t go buying cheap products from unknown manufacturers. If they seem to be amazing value, beware!
Standards exist both for electric propulsion and lithium ion batteries in marine applications.
Ideally, your installer should confirm that installation is to those standards (ISO 16315 for electric propulsion and ISO Tech Standard 23625 for the batteries).
