MASTERVOLT MLI Ultra 1250 Battery Wins 2021 DAME Design Award
AMSTERDAM (November 16, 2021) – Mastervolt, a division of Brunswick Corporation’s (NYSE: BC) Advanced Systems Group (ASG), has been awarded a 2021 DAME Design Award in the Machinery, Propulsion, Mechanical and Electrical Systems and Fittings category for its MLI Ultra 1250 battery. The announcement was made during the first day of the METSTRADE show in Amsterdam.
Making its world debut this year, the MLI Ultra 1250 is the most compact battery in Mastervolt’s range and is ideal for both marine and mobile applications. This is due to the high energy density within the battery cells which together offers up to 70% space and weight savings compared to traditional lead-acid batteries. Weighing just 15 kg and measuring 330 x 173 x 210 mm, the MLI Ultra 1250 offers a considerable benefit for vessels and vehicles where space is at a premium. It has been designed as a drop-in replacement for size Group 31 and Group 49 (85-90 Ah) batteries.
The DAME Awards jury stated, “Mastervolt’s MLI Ultra 1250 lays a significant marker in terms of where battery technology is headed.”
“We’re absolutely delighted to win this prestigious Marine industry award, recognizing our commitment to market leading innovation,” said Ton de Winter, President of ASG EMEA. “We are excited that the Mastervolt MLI Ultra 1250 has been recognized as an alternative green energy source and for its size and affordability making Lithium Ion battery technology more accessible to a wide group of boaters. This also supports our commitment to Brunswick’s ACES strategy, providing unrivalled electrification solutions to our global customers.”
Available in both 12 V and 24 V models, the MLI Ultra 1250 has a realistic lifespan of over 2000 cycles at an impressive depth of discharge (DOD) of 80 %. This deep cycling means five times more energy storage than lead acid batteries thanks to exceptionally high efficiency and the minimal build-up of the infamous ‘memory effect’. As with the whole MLI Ultra range, the MLI Ultra 1250 can be recharged within 60 minutes.

Is there another marine LiFePO4 battery with BMS, cutoff switch, heating pad, and NMEA 2000 output all built in? (Plus deeper system integration with MasterBus or CZone.) This looks like an exceptionally safe and high-performing “drop-in” lithium solution and we judges were impressed.
There will no doubt be people that look at this smallest MLI and complain about it’s cost per watt vs other “drop-in” solutions, but the level of built in safety features as well as the ability to communicate to external systems via MB/CZone is why this will be our preferred battery for systems that cannot physically fit the larger MLI’s. I’m waiting on 7 of these to be delivered for a project underway and looking forward to getting hands on with them.
