Hi Lucy, all our sailboat kits come with a display that shows temp, rpm , current draw and voltage. Hope we don't go to jail over this.

Re: [electricboats] ThunderStruck 10kw kit overheating?

Hi Brian,

From an old and a,

Almost completely satisfied customer. We have Several years now on our AC 34 kit on one side in our 1990 Catana 42 Catamaran "Toolbox". System still works great and does all we need but I would still like to be able to have a display to show voltage, amperage, and RPM at the same time at the helm. Anything new?

Cheers,

Ric Sanders

I think you mean parallel (not series).

If you just have the one large 48V battery, any number of those chargers could be used to charge it,
depending on tradeoffs how much other load you want the generator to supply and how much battery
discharge you want to keep up with (or how fast you want to recover battery SOC).

IOW, my suggestion to use four chargers was before I heard about the four 100Ah batteries being paralleled.
Once in parallel, less than four chargers could also work.

Re: [electricboats] Need smart people help

Thank you Bobkart for the suggestion. I like the idea of using two, gives the system redundancy. I also found the Lester Summit II 1425w inverter. Anybody used these with success?

I also just realized that i will need to series the battery packs for 48v 400ah Lifepo4 with one 200amp 16 BMS.

Re: [electricboats] Need smart people help

I use a pair of Meanwell HLG-600H-54A chargers for my 10kWh pack (16S LFP).
It tops out at just over 58V, but that's fine.  They draw ~700W each, so four of
those would just use up the 3kW your generator provides (with headroom).

Re: [electricboats] ThunderStruck 10kw kit overheating?

Your motor and controller both have temperature sensors along with a lot of other essential metrics made available over CANbus. The fact that the base thunderstruck kit doesn't come with a way to see any of this is criminal. Get the CAN to bluetooth translator or a display you can mount at your helm. Installing some sort of cooling won't help like you want if you don't know what the operating temp is.
