Set Victron smart ip67 to 24v output

Hello,

I purchased the below charger, the Victron blue smart IP67 24v/12a model, and am running into an issue configuring it for my Tesla battery module (6s 25.2v max). When connecting the charger to Victron connect on my iPad I'm able to design a custom profile, but when I set the absorption/float/storage voltages to 24v (trying to keep the battery at 80% as full to help prevent cell degradation and balancing issues) it reverts to a minimum of 25.6v. Is there any way at all to actually get a 24v output voltage on this 24v charger? Or is the minimum actually 25.6? Charging a 6s lithium-ion battery to 25.6v instead of 25.2 will cause an early failure of the pack, if not something more catastrophic. Currently, I have to set timers on my phone and keep a very close eye on the charge levels to avoid overcharging, and that defeats the sole purpose of purchasing a programmable smart charger.


Thanks!

Hi @Kubi Okyay , welcome to the Community!

Unfortunately off-common-nominal voltage battery banks (such as you have) are not supported in Victron (or, for that matter, any other brand of which I'm aware) chargers.

Hi, according to the victron connect demo's you can go down to 24V if set to power supply mode.....

Maybe useful?

Cheers, Leslie
