  1. No it's not better because every 10-15 loads, you need a full charge to make the equilibration of the cells. So you need a 63V output charger to do it.

    ok I will buy it and give my feed back in few weeks
  3. Android Wear Watch

    Do you think this model is OK for using wheellog app on it? https://www.gearbest.com/smart-watch-phone/pp_507114.html?wid=21
  4. A new surprise inside a Ninebot One C+ battery

    2 cells were damaged due to a BMS default. I have already got the same problem with GW battery with Panasonic cells. So the cell's quality is not the reason. I would juste show that Ninebot use different brands for its battery and not only Samsung or LG.
  5. Today I have opened a 220Wh original NINEBOT battery (from a 9B1 C+) in order to make a repair (change the BMS and replace 2 damaged cells). And the surprise was to see the brand of the cells which is DLG. I beleived models C & C+ had SAMSUNG cells and E & E+ models had LG cells. But 2 years ago I have seen on my 9B1 E (240Wh) that its battery was made with SAMSUNG cells (rather than LG brand). And now I've seen DLG brand rather than SAMSUNG inside a C+ model. Can we trust about battery's informations?
  6. Thank you. It was exactly my goal.
  7. OK put 5 differents chargers for 5 differents wheels which have not the same battery capacity and explain that to the boss of a bistro who makes you big eyes when you ask him if you can use his socket. Furthermore, the maximum power is indicated on the back of the charger. In reality the power gradually decreases towards the end of the load, so it is not linear and the calculation of Wh even more apporximative. This tinkering is not at all essential but it can help give a better image of the wheelers in a society where we are always looked like a problem. But maybe I'm wrong.
  8. I present my weekend tinkering, which makes possible to measure the electricity consumption (in Wh) of the devices that will be plugged and used on my power strip. The goal is to be able to reassure the "boss" of bars, when we take a break for refill (and drinks), that one does not eat its margin in electricity with several wheels in charge (quite the contrary, it costs almost nothing) So in starting supply I used: - a power strip : - a measuring and display module designed to support up to 260V and 20A : here is the full link : https://fr.aliexpress.com/item/Accurate-Energy-Meter-Voltage-Current-Power-AC-80-260V-20A-Voltmeter-Ammeter-Blue-Backlight-Overload-Alarm/32694047316.html?spm=a2g0s.9042311.0.0.XUkW81 - for the cutting I used a jigsaw and a cutter, for the assembly I used hot glue and black silicone. To get the following result : I have "sacrificed" the 2 right sockets to position the meter box, the connection is as simple as it can exist: 2 wires in input and 2 wires out without even worrying about any polarity. In practice, 1) I have a socket with 5 free sockets which allows to measure and accumulate consumed Wh (reset to zero with the small black button). 2) the power supply of the power strip and its housing is switched on by the original switch, the operating voltage is displayed. 3) on the same screen I see in instantaneous: the power (in W), the operating voltage (in V), the amperage (in A) and of course, the consumption (in Wh). In the example presented, by plugging my heat gun (power 2000 W to position 2), I have 8.43 A circulating for a measured power of 1953 W.
  9. From E+ to P speed

    Did you ask them if you can buy only the covers with a shipping to USA? If not, you can ask to me to buy it for you and I would ship them to your adress. Just tell me if you need my help for that.
  10. I have made some tests to compare the distance and the speed between 9B app and a GPS (orégon Scientific). The result is the 9B app show a little bit higher speed than the GPS (18 kph for the App vs 16,5 kph for GPS). It's the same for the distance with 1 more km for the App every 18 km. Anyway I don't know any App which give the real speed, I have made the same compare between my GPS and GW MCM4 app, close to 2 kph more for the app when the GPS give 20km/h, and 1 more km for the distance every 10 km.
  11. Where is my 9B1 battery?

    Harder, better, faster, LONGER :
  12. What is actual ninebot power adapter output?

    Some others compoments should be damaged and you couldn't do anything against that. Anyway with the trimpot, you can go down to 50V from 63V, so the trimpot was not the problem.
  13. What is actual ninebot power adapter output?

    50.1V is too low and there is no use to try to repare your charger. best price for a new one seems to be here : https://fr.aliexpress.com/item/2017-Original-Xiaomi-Mini-Scooter-Charger-Mini-Pro-Charger-Xiaomi-Accessories-Ninebot-nine-hoverboard-charger-segway/32820213265.html?
  14. What is actual ninebot power adapter output?

    My charger is not really adapted for a 9B A1 because there is only one battery 155Wh to charge. The original 70W charger is only able to deliver 1.1A in order to respect the speed of load that cells can support without any damage. With a 2A output charger (120W like mine or original 9B1 E charger), it's too high for keeping the good health of cells (of a 155Wh battery)
