Re: [Electric Boats] Re: Li batteries

- They didn't even answer my email. I thought it was because I wasn't in the USA but from what you say you'd be crazy to touch them if you can't deal directly, and what happens if/when you can't?

Cheers

Morning David,

While not setup yet, I have and will be using a dozen of their 12v, 40 Ah batteries – they are the older ones that are black and not the newer, green units. I plan to hook them up in series and parallel to bring them up to 48v, 120 Ahs to power my sailboats eDrive system – a 100 ibl drive from Electric Yachts of Southern California.

I plan on using an ElCon charger, possibly even tied into the batteries BMS, but maybe not...haven't decided on that one yet. At the other end of the system I will be using a Sevcon dc to dc converter: To either power the 12v system directly or to deed a 12v, DC battery charger that will top off the house batteries...again, haven't decided on that part either, yet.

From my experience with Valence, is that direct support from them is little to no hope unless you buy the batteries from them directly. If you secured them elsewhere, say a defunct hybrid car start-up that folded – as a non-specific example – then they won't even sell a BMS to you.

But! They do make an excellent product.
