Most of those who trade on gold don't hold physical stock, even when they deal in physical gold. Money is just a means of exchange. Just look at bitcoin. As long as you can exchange bitcoins for physical gold, then the two are equivalent. The rest is just trade. If war broke out for instance...

flood? we are on a cliff, in town centre.

Saneagle got the faulty items to play with, we don't though. We are looking at prevention.

Battery fires are a relatively small risk. If you get the chemistry right, thermal runaway can be eliminated altogether.

Your example falls into the area of QA in design and manufacturing while the bulk of battery research goes still on their chemistry at the moment.

The risk factors are well-known though. Larger cells are less risky. The problem is how to maintain good gravimetric density with larger cells. Still, the risk is small compared to ordinary petrol oe diesel. The average car has 30-40 litres of petrol or diesel, or about 400kwh, much more than...

We paid France £50 millions in the last 3 years. They stopped and slashed about 30%-50% of the boats. That's roughly 100,000 migrants in the same period, £500 each. We are now offering migrants £3,000 to get on that Rwanda plane. Each person on that plane earns rwanda £1 million plus us...

I use E85 fuel and don't feel guilty about it.

thermal runaway in lithium battery is usually caused either by external short circuit (damaged BMS by overcharging for example) or internal short circuit (damaged separtator for example). To improve the separator. manufacturers now re-inforce them with ceramics.

for most people, kits are not stronger than factory built bikes in the same price bracket. Where kits can and do offer more is flexibility, especially for those who need something a bit special. There are for example very few factory made folding bikes having crank motors, or large capacity...

Besides the slightly higher price, factory made bikes are neater. Cables are routed internally, battery are integrated into the frames etc. Your problem is test riding.

that's the anti-explosion device, just for controlled venting. You need to poison the electrolyte to stop the conduction through the electrolyte. If you act fast enough, that would prevent the electrolyte from heating up.

one thing that puzzles me a long time. I am amazed that nobody has thought of killing the electrolyte or one of the electrodes to prevent the thermal runaway.

That depends on the donor bike. It's best having a chat with Andy. He is online a few hours a day on the website livechat or call him.

I watch on YT the other day a hydrogen powered e-bike. The hydrogen is stored in a solid medium, the rider unwrapped the new hydrogen battery and slotted it in the battery compartment. The recharge at the hydrogen fuel station takes only a few seconds. To prove that the battery is safe, the...

20mph speed limit yes, road bumps and bollards: no. Flower boxes: not worth the money.

the 13AH battery is made with older technology, no match for the new batteries made with 27100 cells.

If you want to install new firmware, you can use stm32 programming kit.
