A bit of background to understand some of our choices.
We have a ship of 24 meters with is used for scouts and their camps.
The ship will lay in remote locations for a longer period of time, this means no shore connection.
Also it wont sail every day most of the time only to the camp location, so charging with alternator doesn’t happen verry often.
We have a generator on board but the less the better of course (cost perspective).
In normal use the ship wont use allot of power only a couple of lights in the evening and phone chargers and the refrigerators.
The ship has a Quattro 24|3000|70 and fits the job for us.
So a big battery pack is just fine for us.
The current batteries are at the end of life that they aren’t useable at all anymore.
We have found an traction battery pack for a fair price consisting of 12x 6Pzs 480 battery’s
With a Volt/capacity of 24 Volts and 533Ah/10h.
We are volunteers organization so funding’s are always an issue, that is why this pack is so interesting for us, It’s fairly good price for allot op capacity.
The big question is how to charge this pack. It consist of 12x 2 Volt batteries, do we need one battery balancer?
Do we need an extra protection/check for uneven 2v battery charging?
Is a standard BMV 702 capable of checking the charging state of this pack?
What are the configurations on the quattro for charging, can these be standard lead acid?
Anny tips for the charging this pack are useful.
