Lithium Battery 12,8V Bank Composition, How to split Bank up

Hi

Planing to ugrade the battery bank on my boat. Is there any advatage / disadvantge using bigger or smaller batteries ?

My thoughts:

If I want to setup a bank with 600 Ah in total I could split up 2 x 300 Ah or 3 x 200 Ah. What wonders me is that when I use the 3 x 200 Ah config it is in total lighter and also bit cheaper. I also whould give me some advantage if one batteries fails.

Does the 2 x 300 Ah have and advantage ?


Thanks for your help

@mark.a

the more batteries, the more cables and connections are required, which naturally can become a problem. In addition, the larger batteries can handle more charge and discharge currents.

I would go with 2 x 300Ah.

Hi Stefanie, thank you for the answer. I really wonder why that setup is about 36 kg heavier

Hallo Sefanie, gerade gesehen, dass Du Deutsch sprichst und gerade ein bisschen bei Dir/Euch im Blog gestöbert. Sehr interessant :-) und viele Informationen. Auch der auch der Teil zu Signal K ist sehr interessant. Wie hast Du das Digramm von allen Victron Teilen gemacht ? Gibt es da eine Software für ? Laut Diagram habt Ihr die 400 Ah Bank ja auch in 4 x 100 Ah geteilt. War das aus Platzgründen ? Lg
