As for fermenting, Mr. Potato Head is just going to have to ferment in place as a learning lesson for jumping into my spokes while going after that beer can so hard!

Re: A potato made me crash my bike and faceplant.

Time to build something more robust. My bikes would plow through a potato stuck in the spokes like it was nothing. Well, now that my mind has cleared up from the heavy punch to the chin, it was one potato the the spokes grabbed, but it was the sack of potato's and the beer can that really locked up...

I will add it to the pile. As for now, the California recycling program has completely collapsed. In any case I am just happy to have my teeth.

A potato made me crash my bike and faceplant.

I hate crashing my bike. I seem to get at least one bad one per year. So this time I was riding back from my local market with a reusable shopping bag hanging from my left handle bar grip. It is something I have done 100's of time before. It was not heavy. I only had a small bag of potato's and four...

Re: Main Wires Fuse Protection

...... About fets blowing I meant the fets of the BMS, why would they blow? ........ That is a question I can't answer except to say that the fets were severely over-volted either on the positive side or the negative side.

Re: Main Wires Fuse Protection

The way you have described the scenario, I don't think you will get any protection from blowing the fets with a fuse inline with the positive battery wire. The phase wires are on a different trace then the power input to the controller and the fets will blow when the phase wires short out. A fuse on...

Re: Noob Electrical schematic !

Hi skidafunk, welcome to ES! Here are a few thoughts, not in any order: Most throttles have kill switches built into them. Why the kill switch? Doesn't the SVMC72150 have an electric lock built in? Why the 30a fuse for the 5a charger? What is the contactor for? Between the ignition and contactor and...

Re: Normal vibrations?

Sounds like something mechanical. Prop up your rear wheel, and with the bike off, spin it and see if it is doing the same thing. Look at all the parts to see if something is rubbing, like maybe a brake part.

Re: Making a 3s parallel pack

A little more general information: When the batteries are in parallel they self balance. When they are in series you need another way to balance them, like a bms. Balancing your cells is one of the points of a bms. What you really need to do is make sure all your cells are the same voltage when you ...

Re: Is it okay to use a 52v 14s battery with a 48v ebike system (48v controller and 1000w motor)

The answer is that you have to check the specs on the capacitors and mosfets in your controller. That means opening it up and taking a look. Most of the time 48v controllers can handle 58.8v, but there are no guarantees. Sometimes one can open a side cover on the controller and see what is inside, b...

Yes, that would be the Northridge 1994 quake. It was a deadly quake, but caused a lot of monetary damage as well.

We will need a lot more information to help with that question, but 1 cell going low usually means you have 1 weak cell.

Re: Controller Trips under load

A few things, Your battery seems to be charging and balancing to the 3.3 nominal voltage (+ or -) of LiFePO4. Full charge is 58.4v. Your BMS is a Best Way Protection Board number 013A (BWPB-013A). I can not find exact data on that board, although it seems to be set at the factory to certain paramete...
