Battery capacity setting in SmartShunt for 2 x 25.6V 100Ah LiFePO4 batteries in series

Q&A and troubleshooting

Hi everyone,

I’m using a Victron SmartShunt and I’m unsure about the correct battery capacity setting.

I have two LiFePO4 batteries, each 25.6V / 100Ah, connected in series, which gives me a 51.2V system.

My question is:

What capacity (Ah) should I enter in the SmartShunt settings?

Some say to sum the capacities (200Ah), others say to keep it at 100Ah since they are in series.

Any tips or corrections?

Thanks in advance!

In series you do NOT multiply capacity so your capacity is 100Ah.

Ofc you now operate a 51.2v 100Ah battery
