Mastervolt introduces new high-capacity lithium-ion batteries
Mastervolt has launched three new lithium-ion batteries – the MLI Ultra 12/3000, the MLI Ultra 12/6000 and the MLI Ultra 24/6000.
Mastervolt’s engineers have developed the larger capacity batteries to be deep-cycle domestic supply batteries for use onboard marine vessels and in mobile applications to provide more power, over a longer period of time, while taking up less space and weight.
“Today’s boats and recreational vehicles are equipped with an increased number of features – these additional power loads make using traditional lead-acid battery banks nearly impossible to accommodate due to excessive weight and size – the MLI delivers optimal capacity,” says Eric Lindquist, VP and general manager of power systems at Navico Group.
“These new MLI models, offer enhanced power storage capacity, in a lighter weight and smaller footprint,” continues Lindquist. “The superior performance of the new MLI lineup will help meet the ever-growing demand for power capacity.
“Mastervolt’s lithium-Ion battery technology offers an innovative solution that is suitable for so many – from racing yachts trying to keep unwanted weight to a minimum, to the camper that wants to stay off grid for as long as possible. Additionally, we believe the MLI series is poised to deliver power solutions to a variety of markets.”
The new batteries will be manufactured at a dedicated production plant, which Mastervolt has recently opened to meet the growing demand.
Lithium-ion batteries are known for their high energy density, offering fast charging, and savings in volume and weight compared to traditional lead-acid batteries. According to Mastervolt, the new models provide 20 per cent more density and 15 per cent more capacity in amp hours, and a greater battery cycle life as a result.
Available in 12 volt for the MLI Ultra 3000 and 12 volt and 24 volt for the MLI Ultra 6000, the new additions to Mastervolt’s range weigh 20 per cent less than previous models. The MLI Ultra 3000 weighs 56 pounds and the MLI Ultra 6000 weighs 103 pounds, making the MLI Ultra 24/6000 lithium-Ion battery a suitable replacement for two 12/200 Ah lead-acid gel batteries in series to provide 24 volts.
The new Mastervolt MLI Ultra 3000 and MLI Ultra 6000 both have a claimed lifespan of over 3,500 cycles and can safely use up to 80 per cent of their capacity before needing to be recharged, offering five times more energy storage than lead acid batteries, which can only safely use up to 50 per cent of their capacity before needing a charge.
The MLI Ultra 3000 and MLI Ultra 6000 can be recharged within 60 minutes.
The MLI Ultra 3000 and MLI Ultra 6000 feature Mastervolt’s Battery Management System (BMS), which ensures the battery can be safely and correctly charged.
The system is equipped with a self-learning balancing algorithm that predicts the behaviour of each individual battery cell and balances proactively, resulting in a faster and more efficient charge cycle. Mastervolt uses lithium-iron phosphate (LiFePO4) for all batteries.
Mastervolt says the new models have easy-to-install features, including two integrated carrying handles with a recess for the correct and practical installation and storing of the cables. The battery poles are easily accessible and completely protected, so no extra isolation covers are needed.
The MLI Ultra 3000 and MLI Ultra 6000 can be connected in an unlimited parallel configuration, and the built-in common-rail technology offers an easy series connection of multiple MLI Ultra batteries. These new batteries have CZone ports built in as standard, making it easy to fully integrate the batteries into an electrical system through a choice of the CZone platform, as well as the MasterBus and NMEA 2000 protocols.
Pricing for the new batteries are as follows:
- MLI Ultra 12/3000 is priced at € 3.199
- MLI Ultra 12/6000 is priced at € 5.645
- MLI Ultra 24/6000 is priced at € 5.645
