  1. yes it's better to switch to output protection in order to be direclty on + and - battery poles
  2. This is the link for my first post for 9B1 DIY battery (on french forum but you can use a translator): https://forum.urban360.com/index.php?/topic/223-fabriquer-ou-plutôt-assembler-sa-propre-batterie-pour-9b1/ And you can read this post too : https://forum.urban360.com/index.php?/topic/1091-batterie-ninebot-one-hs/&do=findComment&comment=17515 Hope that will give you some help.
  3. Original BMS on 16 inch NINEBOT ONE model don't make the difference on number of parallel, you can add an other series with 15 cells without any problem. thank you for your humorous message even if a fall is never funny. Need to move my feet and to make some break to avoid problem.
  4. under 42V, the original charger does not detect the output power of the battery (such as not being connected) and that is why it does not give full power to the load. But you are right, there is a very small current going to the battery and the voltage increases very slowly. In this case, you'd better use a lower output charger (10S or less) to increase the voltage near 40V, before trying with the original segway charger. the other solution is the "electroshock" method which was described in this post, by connecting 2 batteries in parallel (the faulty battery to a functional and well-charged battery). There is an instantaneous high current transfer so you have to do it only for a few seconds at a time. it’s more barbaric, it requires a second battery but it wakes up
  5. it's seems to be a different problem from the main subject of this thread and the solution should be different too. the spark is normal as you link first your charger to the battery, because if the charger is not "power on" current will go from battery to charger (inside condenser ask for "juice") that's why you always should plug your charger to sector before to link to the battery. BUT IN YOUR CASE, I ADVISE YOU TO NOT DO IT. If your battery stop to load at half full it can be 3 issues : disequilibrated cells, BMS failure or charger output decreased. First, use a voltmeter to check your charger output. Second, check cells with NINEBATTERY app. If charger is Ok and cells are OK, so it's your BMS the problem no risk, no glory
  6. I have no picture but I can say there is no other choice to link both batteries than to do it before the XT60 connector from each battery. I have directly soldered wires for external plug on it. And same problem for the external plug, no more possibility to put it on the shell due to the shape. open your shell and you will understand what I'm speaking about.
  7. I have put an external plug on my Z10 and this plug is link to both XT60 inside the wheel. So Battery 1 and Battery 2 are linked together and the wheel works perfectly. With my externel plug I can link my external battery (14S4P that give 12,8Ah) that give power to both battery and I can have a faster load if it's needed.
  8. It makes me think about
  9. Hi the community, This is the BMS from an old S300 (16s lifepo4 cells). Cells are dead and I want to replace this battery by a new li-ion battery (14s with it's own BMS). But the S300 will not start as this wire (at SIN place on original BMS) is not link to the motherboard with the new battery. Does somebody know what the function of this wire is? How can I link it on a generic BMS, if it's possible? Many thanks in advance.
  10. Yes original 9B1 BMS is the weak point of this wheel, but I have 3 or 4 times (not on the same battery) replace it by a 16S "no name" BMS that give more security for driving. If cells are OK, you can try to do the same and you will found all details on following link :
  11. I only use the GX external plug (I have added) for : - high speed load over 5A (I put my 8A charger or both 5A and 8A at same time = a 13A charger) - my external battery in order to raise my range I use orginal Z10 charging plug for normal load (at 2A) or for medium speed load with a 5A charger In my case, I can't connect chargers and external battery at same time to the GX plug. That's why I link my 8A to the GX in order to load my Z10 and I use my 5A charger in order to load separately my external battery. If I wanted to load internal and external batteries at same time, I can only use my 5A with the original charging plug of the Z10.
  12. Yes it's possible like the description you've given. One extra battery for each internal one. My Z10 is composed by 2 packs of batteries, I have linked both batteries on output power wire and put an external plug. Maybe It can works with the S2. yes exactly, I have 2 chargers and It's faster to load batteries separately.
