Multi voltage battery chargers - 110 and 230v

[rhys_o]

Do chargers exist that can work at both 110 and 230v? It seems mad that you'd have to pick one or another. I have a large 280Ah LiFePo4 battery and want to be able to give it a lot of juice (30a+). Victron is my usual go-to but in this instance I can't find an option in their range.

You could look the Sterling pro charge ultra range, 80-270V AC

The rolls Royce of chargers where money is no object, good luck

Awesome, thanks both. They come with a hefty price tag. I think I might just get a high amperage switching power supply ~15v 30A and just link it up to my existing Victron Isolated DC/DC charger. Thinking that I won't ever be running the engine whilst on shore power so can't see it being a problem.

Anyone see any potential issues with that?

Edit: I realised that I have spare server power supplies (70a @12v) that will run on 110 or 230v that I can use as the switching power supply for the DC/DC charger. Only downside is that they're noisy, I'll look at replacing the fan with something a lot quieter.
