Settings for Numax battery for Victron 75/15

[Sabino]

I have a 12V 105AH Numax DC25MF.
I asked the company for recommend settings, the came back with
Voltage settings 12v

Daily charge 14.8
Float charge 13.5
Equalize charge 16.2

How should I set up the Victron controller?

Many thanks.

I would think that the daily charge would be the absorption charge on the victron. The float charge as it says. An equalize charge is only needed for two batterie.

14.8v is far too high for a standard flooded cell battery. Just use the Victron standard setting for flooded cells.

Sorry I misinterpreted the question, so deleted my answer

Many thanks everyone for taking the time to answer. I was at the football last night and am just now getting to the PC.
I'll have another look at the settings today hopefully.

Many thanks for your replies

The battery default choices I see are

Default (Gel Victron deep discharge 2) which it is still set at

then

AGM Spiral

Gel Victron deep discharge (1)

Gel Victron deep discharge (2) This is being used

Gel Victron long life (OPzV)

I don't see one specifically for my flooded wet cells.



Many thanks again

In the manual, gives for each preset the voltage values.
Which one is close to yours?
Failing that, you need a Bluetooth to connect to it via victron connect app, and select user defined. Then you can put the voltages you want.
I’m sure one of those presets, 2 or 3 will suit your battery.

May I point out the equalise charge has nothing to do with the number of batteries. It's nothing more than an overcharge to remove sulphate crystals.

Know how to apply an equalize charge that benefits the battery. It removes sulfation that may have formed during low-charge conditions.

Hi, Can you name the company that provided you with these figures ? They simply do not make sense and some plainly wrong.

Default setting are the correct ones for flooded cells see here:-

Thanks for this information. Many customers give Tanya good feedback and that in my opinion is because they do not allow any negative feedback to be posted. They are no more than a stockist and I have found them tom be wanting and having to return batteries that were delivered under 12.4 Volts. I'm now of the view they should be avoided altogether after providing customers with this type of information.

I wonder why there isn't a preset for FLA batteries on the Victron App, it must be confusing to a lot of people
