48V 700Ah -- 16 series Winston cells like these, with a custom BMS integrated over CANbus with the Victron inverter/charger/MPPT:

But don't forget this is a series hybrid boat, with a 9kVA generator and a 15kW motor (continuous rating -- 25kW peak), so it needs a hefty battery bank... 😉

Wow, your batteries cost more than our entire 70ft boat.

Nice! When you say custom BMS how has it been customised?

Never said they were cheap -- but then neither is the boat... 😉

 

BOAT = Bring Out Another Thousand is proving spookily accurate yet again, guess how much the generator supplier hiked the price by a week before delivery... 😞

It's a custom BMS made for Finesse for exactly this purpose -- a hybrid boat, with proper integration with Victron electrical gear, the drive system and generator.

So in what way is it customised?

Ask Finesse... 😉

 

There are various things they do that they've spent a lot of time and effort working out, and understandably don't want to give details out so their competitors can get the benefit without doing the same -- as an interested (and paying!) customer I know details about some of them but I'm not going to tell either... 😉

Not enough zeroes, as I said... 😞

Series hybrid is the obvious solution as long as there remains a canal system on which to use a boat. 

 

Many yarrrs ago one would have found hanimals used for the purpose of towing boats. I still think all this propeller nonsense is going to end in tears.

I'm not sure anyone on here has them to be able to make a recommendation. 

 

Lots of satisfied customers of lifebatteries on Facebook though. 

 

Lifebatteries are selling batteries from XD Battery who use the same components as Fogstar I believe. i.e Eve Grade A prismatic cells and JBD BMS.

If you look here, you'll see some of them are marked "archibald", which you'll find here.

 

They're also sold by Bimble who's datasheet show Mark at Lifebatteries as the EU contact.

Only 2 of their battery range have built in heating

 

To be clear, I wasn't recommending them over Fogstar. Rather just stating that the components are the same. In fact, although the customer service was good, I had to return one of two orders for replacement, and wasn't overly impressed by a third.
