Plus it's easily recreated in the future if there is any need. I have never understood those who want to build an hydrogen economy.

Don't you miss cooking with gas?

Yes, it was 9 years old when smoke came out of the battery.

One of the pouch cells, none of the Panasonic and Samsung cells.

The cheap ebikes that I sold in the early years had lead acid batteries. The more expensive bikes of 14 years ago had 36V 10AH rack batteries and pouch cells. For the last 10 years, we use only Samsung and Panasonic cylindrical cells. We stopped top up charging ever since going for cylindrical...

Look at the facts, covid is so widespread that almost all of us have been exposed to it. I myself have had covid 3 times, I doubt that another jab is going to change the probability of me getting covid again or that I will fight it better i next time I get it. This said, I am still going to get...

when a cell goes bad, for example developing dendrites which act as micro-shorts, it usually causes the cell to heat up and the block to have a lower voltage than otherwise. There is no simple way for the BMS to detect this. Eventually, the shorts spread and start a fire.

Vaccines don't cure diseases, they don't attack the disease, but prepare your body to fight the disease much sooner than otherwise. The net result is the disease becomes less severe, at least theoretically. The problem with covid vaccines is that our body still doesn't know how to kill the...

I am not sure that the BMS is at fault in those situations. It could well be that one of the cells has gone bad, causing the charging process to continue until the bad cell starts to burn. IMHO, that situation arises because the internet promotes ridiculous price comparison. Before the age of...

No, the figures relate to e-bikes and e-scooters fires.

there were very few e-bike fire incidents before the e-scooters arrived. It could well be that very few retailers realise the risks posed by e-scooters. Unlike e-bikes, e-scooters motors don't have gearboxes so they run at easily double the current and power of bikes even at slower speed...

all the big name GPTs have alignment (on morality and societal issues). If you use the word chemtrails, they assume that you are a conspiracist and won't answer your repeated questions unless you run the model locally.

How heavy are you if you don't mind?

the number of people injured by batteries fires: 51 injuries, 3 deaths out 104 battery fires last year in London. The chance of being hurt is very high when people bring their bikes indoors.

Amazon ai is a bit behind atm. Test it again next year.

Quite funny.

I think it was on YT Sam Evans the electric Viking. Apparently, e-bike fires injure 10x more than EVs fires. I can believe it. You wouldn't park your EV in the hallway would you?

I believe that's down to product liabilities If one of their bikes explodes. There are some statistics showing that a lot more people are hurt by exploding ebikes batteries than electric cars batteries.

nice bike.
