51v battery

[Toddmccollam]

Lithionics sells 51v batteries. Which are clearly 48v batteries they added an extra cell to, on the assumption that 48v chargers have enough play in them to handle the extra 3 volts. Is there some downside to this, would it be bad for the charger, inverter, or 12v dc converter?

Ah, after I posted this I noticed one downside is the cells I want are sold 4 at a time. So this might be irrelevant.

"48"V LFP batteries are 51.2V nominal.
16 3.2V cells is 51.2V.
24V batteries are 25.6V nominal.

So I have it backwards, 48v commercial batteries are 15 3.2v cells? I just assumed the 48v was nominal and they're really 51.2. Like they do with the 12v, which are actually 12.8.

Ok so what's 12.8V x 4? 51.2V
3.2V x 4 is 12.8V
48V LFP batteries have 16 x 3.2V cells
24V batteries have 8 x 3.2V cells

I shall stick with the standard 16 cells then. I was thinking of getting greedy and trying to squeeze in one more. I had a feeling it was a bad idea though, which is why I asked.
