Mastervolt Batteries
Mastervolt makes selecting the right battery simple. Whether you choose a low priced battery such as AGM or an innovative and advanced Lithium Ion battery, Mastervolt has the right battery for every application. Mastervolt has divided its entire battery range of 36 types into seven series and five different battery technologies. Each series has its specific features.
All Mastervolt batteries offer you these advantages:
Maintenance-free.
Safe – no gassing.
Easy to install.
Designed for cyclic use (charge/discharge).
Minimum self-discharge.
Two year warranty.
GEL batteries
In Gel batteries, the electrolyte is absorbed by a Gel. This type of battery is entirely maintenance-free and has no gas formation with normal use. As no extra ventilation is required, Gel batteries can be installed anywhere. They are ideal as service battery and for cyclical use, and can be charged very quickly.
Perfect service battery for medium sized and large 12 V and 24 V systems.
Extremely long lifespan..
No gas formation with normal use..
Fast recharge, high charge current possible..
For intensive cycle use with a high number of charge/discharge cycles..
Very low self-discharge..
High return on investment..
Two year warranty.
AGM batteries:
In AGM batteries, the electrolyte (mixture of water and sulphuric acid) is largely absorbed in glass fibre. This type of battery is entirely maintenance-free and there is no gas formation with normal use. Not requiring any ventilation, AGM batteries can be installed anywhere.
Their construction gives a very fast discharge at very high currents so AGM batteries are ideal for systems that require high currents (for instance when starting an engine). The battery poles can be unscrewed and this type of battery can be combined with every standard battery terminal.
Excellent starter function.
Perfect upgrade for flooded lead acid batteries.
Same initial power surge in an AGM 12/90 Ah as 180 Ah flooded lead-acid battery.
Glass-fibre technology ensures low internal resistance.
Lithium Ion:
Lithium Ion is the battery technology of today. Do you want to be the fastest or best performing? Do you want to save energy or burn less fuel? Do you want your investment to last longest? Do you want to be ‘out there’ longest without getting anxious about your energy? Then Lithium Ion is your choice of batteries.
Lithium Ion batteries have a high energy density, offering savings of up to 70 % in volume and weight compared to traditional lead-acid batteries. They are perfect for cyclic applications, making over 2000 cycles with very deep (80 %) discharges, effectively storing 5 times as much energy over its lifespan compared to lead-acid.
A few of its outstanding features:
Space and weight savings up to 70 %.
Three times the lifespan of traditional batteries.
Extremely fast charging and discharging.
High efficiency: not wasting energy.
Safe operation.
Safest Lithium Ion technology available
The term Lithium Ion encompasses multiple chemistries, having slightly different compositions of materials. These differences result in variations of energy and power density, lifespan, cost and safety. As safety is our primary concern, Mastervolt chooses to use only the safest available Lithium Ion chemistry, Lithium-iron phosphate (LiFePO4).
Mastervolt brings Lithium Ion technology in two product ranges
MLI series; Large capacity series, fully equipped for extreme cycling, like running airconditioning, pumps or electric motors for long periods of time with short intermittent charging.
MLS series; Small capacity series, suitable for smaller applications, such as portable/mobile equipment or backup power.
Safe Operation
The Mastervolt MLI series is equipped with an integrated Battery Management System (BMS) and communication through MasterBus/ CAN. Even in the harshest cycling conditions this guarantees efficient and safe operation of the battery.
The MLS batteries come with an integrated automatic safety switch. Safety always comes first.
Weight Reduction
As speed and performance are crucial aspects, a Lithium Ion battery with 70 % less weight than similar lead acid batteries offers considerable benefits. A vessel or vehicle with a storage capacity of 20 kWh on board, can easily save up to 500 kg and achieve a substantially better performance.
Superior Performance
Mastervolt Lithium Ion batteries have a realistic lifespan of over 2000 cycles at a depth of discharge (DOD) of 80 %. This means five times more energy storage than lead acid batteries thanks to features such as extremely high efficiency, the almost complete absence of self discharge and the minimal build-up of the infamous ‘memory effect’.
Suitable for large battery banks
The MLI series is ideal for electric and hybrid applications, and can be connected in parallel unlimited. The built-in common-rail technology offers an easy series connection of multiple MLI Ultra batteries.
Easy Installation
The MLI series includes two integrated handles with a recess for the correct and practical installation of the cables. The battery poles are easily accessible and completely protected, so no extra isolation covers are needed.
The MLS batteries make a great ‘drop-in replacement’ for a system with lead-acid batteries, because no system changes or additional components are required.
