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.

Is there another bike shop not too far away? And what is it that you need done? In case of difficulty finding a friendly bike shop, please email support@wooshbikes.co.uk we will put you in touch with someone who can help.

it is because the difference in approach between KT and Lishui. KT let the customers set up the parameters for their controllers while Lishui supplies firmware to OEMs. Being an OEM, I can select which firmware to use to minimise support issues. The result is clear: nobody asks how to change the...

They drink too much of the stuff

You need to test ride the bikes as many as possible because of your lack of space and fitness. Which part of the country do you libve?

Doesn't her fazua have a rear hub kit?# edit: you are right, it has a crank drive motor and a hub gear.

Wheel size doesn't much affect weight though. Katy is happy with the size of her fazua. She only needs a bigger battery.

:D :D if you don't pay income tax, are you still not nicking anything?

I don't disagree. The choice comes down to personal preference.

Likewise, you can go for a 48V crank drive kit if you need more power. The advantage of cranks versus hubs is cranks can take advantage of chainring to cassette gearing while hubs can't.

thank you. I thought he got the bikes mixed up.
