Re: Help Needed with Fastest possible Electric JetSki Conver

Anyone any ideas? I know water and electric dont mix but that doesnt mean i should keep it low voltage, Ill just have all connections well insulated, would i be safe enough using LiPos or should i use the older style 18650 LiIon cells as they have a harder metal shell?

Power Options for Off Grid Cabin in Northern Ireland

Hi all, I've ha d a friend ask me to look at which would be his best option for getting some 240VAC to his cabin in the mountains, The weather here is quite poor most times so we were thinking maybe some sort of combo setup like some solar pannels and also maybe weld up some home made turbines using...

Re: Bafang BBSxx - fault finding and fixes

Just turned it on without heat sink, Think I blew a mosfet, deffo seems to be lose wire though cause when i power it on i get error 30 then move wires and it comes on, Mosfets currently on this are 6 75nf75 and 3 irfb4310 rectifiers, Should i replace all 9 or just the mosfets?

Re: Bafang BBSxx - fault finding and fixes

Have you checked the connections inside the motor/ controller casing. They can come loose and are / should be glued on at the factory. Yours sounds like a intermittent connection issue and does not sound like a display issue to me. I would not mess with any of the wiring. Something as simple as a F...

Re: Bafang BBSxx - fault finding and fixes

I agree, you shouldn't have to pay the shipping. So argue your case with PayPAl. You were sent a defective item and you should not be held responsible for return shipping. Talk to your credit card company about stopping the payment. Technically, when I had my problem I contacted PayPal first as you...

Re: Bafang BBSxx - fault finding and fixes

And why are you "stuck with it"? I received a 750 kit from a Ebay that dumped right after I got it. I contacted PayPal and my credit card (American express) and got every dime back including shipping. And they didn't want to pay for return shipping and customs so I still have the bad kit. It only n...
