GT16 beeps and tilt backs


Recommended Posts

Hello,

In couple of weeks I'm going for GT16 as an upgrade for my Segway Ninebot S2, which has over 2 000 km now. Even though, I'm usually pushing at top speed, I got used to ride only with my wrist protectors. As for the GT16 I have actually bought a sturdy scooter type helmet (no chin, but with the glass that could be pulled in and out) and the thin foam knee protectors (for dirt bikers) that go hard on inpact. Just in case I would encounter some sudden cut off, which has never occured to me with the Ninebot and makes me a little bit scared, as it's Rockwheel, you know. Yet I haven't actually found any post that would suggest these actually happen with the Rockwheel.

One thing that still bothers me is possible overcharge. As I actually live almost at the very top of the city. My ride always starts as a downhill ride. Not the whole time though, more like 30 meters steep, then 200 meters flat and so forth. Never thought about it with Ninebot and never had a single problem. Yet in other post here I read, when the beep from overcharge happens, you have to stop like RIGHT NOW, or faceplant is inevitable. Is there also a TILT BACK for every type of beep, including overcharging? With my new helmet I'm not 100% sure I would always hear the beep. And the added noise from the traffic wouldn't help it either.

I'm going for the 858Wh from the Rockwheel Store at Ali. The description is a bit outdated since it's talking about 60V vs 80V, but it actually seem both to be 84V and only difference is battery capacity. So I hope, buying the cheeper one does not go with the extra overheating as the description suggests since it's actually talking about 60V. Also it's hard for me to distinguish V2 from V1. I hope it's already only V2 their selling. With all the beeps and tilt backs in place ?

Welcome to the forum. ??

 

I have the GT16 with 858wh for more than 1 year  with over 1300km and can’t say anything bad about it. I bought it from the same seller.

 

As far as I know they only sell the 84V version. So with the 858wh Version you will not make any mistake. ?

 

@Yi Chen maybe the description text at the GT16 article on AliExpress needs to be updated. Thanks 

 

But with 100% charge I would not recommend start riding immediately downhill...

Thank you, can't wait.

Makes sense, yet it's gonna be a bit hard to check the wheel all the time while charging and plug it out before it hits 100% (plus it need to be fully charge from time to  time anyway).

What about the beeps. Are all the beeps accompanied with the tilt backs?

It isn’t at all hard if you use a charge doctor http://hobby16.neowp.fr/buy/ you can set it to stop charging at a particular voltage or when the current drops to a threshold value (say 1 Amp for example).

You are correct, the simple balancing circuits in most BMS (Battery Management Systems) only start to balance the cells once close to full voltage. However you do not need to do it too often (say once every 10 charges or so) especially if you don’t fully charge or fully discharge. I.e. balancing is most important if you know you are going on a long run where you need every Wh and may run the battery low as well.

I never tried that or made an experience with 100% charge riding downhill and if it is tilting back... Also if we ride with the kingsong KS18A and the rockwheel, the batteries got earlier empty on the KS18A instead of the rockwheel. ?

But ones I think it was about 15-20% charge it beeped shortly with tiltback if you are to fast. But most of the time I started charging at 20-30% till 100%.

@Scatcat maybe you can share your tiltback/beep experience? ?
