  1. Do you know if your e-bike has battery cell balancing? It's possible that the individual cell is ok but can't charge as well as others in the string. This would cause the whole string to go down.
  2. Yes I agree. There are many who think they have enough knowledge to overcome all obstacles. That is where regulatory authorities come in. They will require these e-bikes to have been type tested and a certificate of conformancy issued. This would be much the same as washing machines and other domestic appliances. Maybe have the BSI Kite Mark
  3. Electronics can indeed be cheap. There is, of course, some degree of electronics regulation because all these e-bike are fine being recharged. But that could be only constant voltage with no current limit. A high internal resistance cell would overheat possibly to the level of combustion. This is where the other type of regulation comes in. There are regulatory authorities tasked with protecting consumers from being sold goods of dubious/dangerous quality. They require government legislation to act against these shoddy goods. So governments need to get their fingers out and pass legislation to ensure the unaware consumer has some sort of protection.
  4. The BMS (battery management system) is a bunch of electronics used to control and limit the current passing into and out of a lithium battery pack. It also limits the charge voltage to a level so as not to overstress the battery. A battery cell monitoring circuit is generally included in the BMS which is used to make sure all the cells get charged to the same level. I have seen cheap e-bikes on sale in Thailand. There is definitely no battery cell monitoring going on and the BMS must be presumed to be in the charger if it exists at all. If you buy one of these cheap e-bikes the result could be this: https://news.sky.com/story/call-for-government-to-fund-safe-e-bike-subsidies-after-battery-fire-12915065
  5. This is where health and safety training is vitally important. If "his colleagues" had a bit of training they would have immediately disconnected power which may have saved this mans life. Note: There was absence of a ladder so how did the guy get up onto the roof?
  6. Not surprised. Mine would demand same also. How ever many you have and wherever located they will be in the wrong place and never enough..............
  7. Due to high volume of access. = Your fault not ours.
  8. But only has one eye.................
  9. As one envious man was heard to say to his pal with a new haircut. "That's a really good haircut you have. Was it done professionally?"
  10. Yes but give them time to get the ticket booths built first and erect the sign of prices for farang and Thai visitors.
  11. Yup. The one in the picture looks like a juvenile golden tree snake to me. Harmless to humans although bite can hurt similar to a hornet sting.
  12. In Thailand, government bureaucrats wield tonnes of power especially over the poor citizens who mentally cower before them. It is incumbent on these bureaucrats to have their "customers" run themselves ragged for no real reason other than for their personal satisfaction.
  13. Yes. They all went to the Putin school of truth, ethics and diplomacy.
  14. Cups not big enough for that amount of tea perhaps?
  15. So first he was arrested by Pattaya police then he was apprehended by immigration police. I'm guessing he was released on bail by Pattaya police and, whilst free to prepare his case, was picked up by immigration police. What was he detained for by immigration police.
  16. Do you mean signature witness? My local hospital GP does it free.
  17. Turkish - Seni seviyorum
  18. Camsahamnida 감사합니다 This one worked a few times. 사랑해 니 팬티 벗어
  19. You could get one of these and adjust the pressure switch how you want. https://shopee.co.th/product/15521089/10544863728?gclid=CjwKCAjwkeqkBhAnEiwA5U-uM5pO3Pu_ykNow0w6BzyT8bcEZs2MKdsIto0hHRlnInzHFxpSF4AI0BoCDAEQAvD_BwE
  20. Too many spots of yellow paint for me...........
  21. I like the idea of the screen. Although it's not clear from the picture, I guess your roof fixed box section will be attached to the high points of the roof steel. Will you be making it in removable units for access/ease of replacement?
  22. All back to normal now. What did I do? Well nothing actually. Problem is now filed under Wierd.
  23. Tried that...............Nah. Nothing. I normally click Windows start button bottom left then click on news. That gets me loads of item windows which is fine but when I click them nothing is the result. White screen with that circle thing going round in the middle. I can get what I want on Sky news so it's no big deal. Just wondered .............
