Important Concepts for Upgrading Batteries
Battery Capacity
Battery capacity will be defined as Amp hours (Ah) at a certain Voltage (V) or Watthours (Wh or kWh). Wh/kWh is a more accurate expression, avoiding confusion about V. The battery capacity should be matched to the daily energy usage with a 20%-40% buffer to increase battery life expectancy.
Battery Voltage
Most recreational boats have operated at a system voltage of 12V in years past but more and more boats are moving to 24V and even 48V with higher loads and faster charging capabilities. Operating at a higher voltage reduces current and voltage drop. This will reduces cable size resulting in weight and cost savings.
Charging Algorithm
All batteries have a recommended charging algorithm. For lithium, adhering to these recommended charging parameters is important for safety and battery lifespan. When considering an upgrade to lithium, it is important to make sure that all chargers are programmable to the recommended charging parameters.
Lithium Battery Chemistry
There are many different types of lithium batteries on the market. Each one has a different set of attributes related to stability (safety), energy density, & cost. Lithionics and Victron use exclusively lithium iron phosphate which are known as having a very good balance between energy density and safety. This is a different and safer chemistry than the batteries that caused many of the boat fires that have been publicized.

Other Things to Consider
Charging Capabilities
A high output (HO) alternator can greatly increase your charging capabilities and improve your system’s performance. Read our FAQs about HO Alternators and lithium batteries for more information.
Monitoring
Monitoring the state of charge (SOC), the charge rate, the discharge rate & the V of the battery bank is necessary in order to maintain the health of the battery bank. There is a wide variety of products available depending on the features desired.
Wiring
When installing batteries, it is important to ensure that all the batteries in the bank are loaded equally during charging and discharging. This means that cables of equal gauge and length should be used when connecting the batteries in parallel and to the system positive and negative buses.
