Makspower MP 100 Mk.2 Dynamo for Lithium battery (Yanmar)

Original price was: kr 8.490,00.Current price is: kr 7.990,00.

Makspower MP100 Mk.2 Dynamo

Built-in voltage regulator:
For robust and easy control of alternator temperature, charging voltage and safe charging

External sense: The dynamo's sense wire checks the voltage on the battery bank's + pole, for maximum charge and full control that the batteries are not overcharged.

Maximum charging voltage:  14.4 volts
The built-in voltage regulator stops charging at approximately 14.4 volts or slightly below. This is the perfect maximum charging voltage for lithium batteries and most lead-based batteries such as AGM and GEL.

Charging at idle: about 50 Amps +, which is more than many original alternators at full speed.
Makspower MP 100 Mk.2 is perfectly programmed for cargo of Lithium batteries and lead-based batteries

Description

Makspower MP 100 Mk.2 Dynamo for Lithium Battery

For Yanmar engines sets a new standard for fast cargo. 
 
After two years of testing in the demo boat SØNDAG, where the MP 100 MK.2 alternator has been charging Makspower 1200 Ah lithium battery bank, without a single failure, we can see that this alternator has delivered the goods. 

Upgrade to Makspower MP 100 Mk.2 alternator and utilize the lithium batteryes incredible ability to take against A lot of power. 
 
Makspower MP 100 Mk.2 has charged 5-6-7 and 800 Ah straight up in the fastest possible way. 
The alternator charges up to 180 amps + when cold and around 120 to 130 amps at working temperature. 
 
Makspower MP 100 Mk.2 is perfectly programmed for cargo of Lithium batteries and lead-based batteries 
Max charging voltage: 14.4 volts

Built-in voltage regulator:
For robust and easy control of alternator temperature, charging voltage and safe charging

External sense: The alternator's sensor cable checks the voltage on the battery bank's + pole, for maximum charge and full control that the batteries are not overcharged.

Maximum charging voltage:  14.4 volts
The built-in voltage regulator stops charging at approximately 14.4 volts or slightly below. This is the perfect maximum charging voltage for lithium batteries and most lead-based batteries such as AGM and GEL.

Charging at idle: about 50 Amps +, which is more than many original alternators at full speed.

Prerequisite for installing the Makspower MP 100 Mk.2 alternator:
With amps that can exceed 180 A, the electrical system must be dimensioned for that much current.
Upgrade from Hitachi alternators:
The original power system of Hitachi alternators is not capable of handling this much power. It will charge two to four times faster with the Makspower MP 100 Mk.2 alternator.
The cables from the alternator to the battery separator (electronic battery separator such as Victron Argofet 200 with two or three outputs or equivalent) and all the way down to the battery bank must be at least 50 mm. For best results, use 70 mm cables.
This applies to the plus side and the minus side. 

It must be possible to equip the Yanmar engine with pulleys for a flat belt.
It is not possible to run this alternator on a V-belt. The belt will slip.

Converting to a flat belt is very easy. You do it yourself.

New tensioning arm: Yanmar supplies a tensioning arm with a set screw that makes tightening and retightening the belt very easy.  

Valeodynamos originally supplied with newer Yanmar engines
This dynamo uses a flat belt.
This means that the Makspower MP 100 Mk.2 alternator fits right in.
It is likely that the original belt from Yanmar can be used (same length).

The Valeodynamo is normally delivered with the original tensioning arm.
It is necessary to keep the belt tight and easy to retighten.

Which motors can be converted to flat belt and Makspower MP 100 Mk.2?

Yanmar engines that can be upgraded to flat belt serpentine belt:
2YM15
3YM20
3YM30
3JH4E
4JH5
Other Yanmar engines can also use the Makspower MP 100 Mk.2 alternator

In the tensioning arm kit from Yanmar there is a special bolt that does not fit.
Makspower has a proprietary bolt that you can order from us. 

Considering the Makspower MP 100 Mk.2 alternator for lightning fast charging:
Contact Makspower and state which Yanmar engine you have.
We check what it takes to convert to a flat belt.

Do you have a Volvo engine?
Contact Makspower for twice as fast charging. We have good solutions for most Volvo engines used in sailboats.
