Hi,
Maybe this helps? https://www.zapiinc.com/sites/default/files/ZAPI%20SEM-1.pdf
I think the ability has more to do with maximium Amperage the controler can take, but tell me if I am wrong!
I have a Duffy 18, on 36V Lifepo4 and the original Curtis controller which is only suited for 36V.

Onderwerp: [electricboats] Replacing FLA Batteries with Lithium in Duffy Electric Boat
Hello, All,
I have an older 16-foot M160 Duffy Electric Boat, which is a somewhat rare model with a hull similar to a tri-cat. The lead acid batteries in the boat (8 220 Ah 6V GC2's) are nearing end of life, and I'm considering upgrading to a 48V 150Ah lithium ion battery, specifically NMC chemistry (13S @ 4.2V=54.6V max).
The boat has a 5hp motor connected to a Zapi SEM-1 controller. Should I be at all concerned that the NMC battery will provide 54.6V to controller? Are controllers generally able to handle this level of over-voltage?
Thanks in advance for any helpful comments or perspectives you can provide!
