Can I read cell voltage with a Victron Shunt?

Q&A and troubleshooting

Hello everyone,

Newbie: I have a Victron Blue Smart Charger IP22, this I was using to charge my 2 Fogstar Drift ECO 100AH Lithium Batteries, via fast charging directly@30A

Now I have had to set up my batteries to charge via the charging XLR port on my wheelchair controller.@13A

This I am in the process of doing(I have to make up a charging cable), I need to make a cable from a SB50 Anderson Connector to a XLR 3 Pin Power Plug.

With not being able to charge @30A, but 13A, this extends the charging time, with a bit more care on charging voltage.

This lead to the idea of using a Victron Shunt. But leaves me wondering if the Victron Shunt would give me Cell Voltage in each battery or just the overall voltage.

Any ideas/suggestions/advice would be greatly appreciated.

Apologies for the long way round.
James

Update: thanks to all for your support, I can now say that I have my Victron Smart Shunt 500a wired and working with my electric wheelchair with midpoint monitoring on my second battery. I have only to use and test the monitoring for Soc as I go.

Happy New Year to all.

Kind regards

James

The SmartShunt only monitors the overall battery bank, it can’t see your cell voltages.

The shunt can only monitor a battery’s current, not the voltage of each cell within a battery. The shunt itself is not a voltage monitoring device, it’s a current monitoring device. The BMV-712 battery monitor has the ability to monitor the voltage of 2 separate battery banks, one of them being the one the shunt is connected to.

Thank you marcham for your timely reply, it looks like I will have to install the shunt the right way, at least that way I can keep an eye on the ah.

Then, I just need to create the charger to power chair cable.

Once again, thank you marcham😀
