Paulandjacquelyn Posted November 15, 2015 Share Posted November 15, 2015 I just saw that there is a super charger that can reduce charge time by 50%. Does anyone have this and also is there increase battery fire danger? Link to comment Share on other sites More sharing options...

ninebot156 Posted November 16, 2015 Share Posted November 16, 2015 I read that it would shorten the battery life by 50%? Link to comment Share on other sites More sharing options...
EUC Extreme Posted November 16, 2015 Share Posted November 16, 2015 That's not true. It will shorten the charging time by 50%. With the lifetime of the battery does not have anything to do. 18650 batteries will last easily for faster charging. In particular, if the battery is big.

BPINE Posted November 16, 2015 Share Posted November 16, 2015 The larger the battery the more amps you can through at is because the amps are divided among more batteries. The uni industry really need to go towards lipo in the RC world the discharge rate is far greater and the charge rate much faster. As an example a 12s 5000 mah pack can be charged at 50 amps or more in some cases. I pull over 200 amps out of a 12s lipo pack in some of my large heli's.

Even in the RC world there is a huge difference between the rate at which a LiPo can be discharged and the rate as which it is safe to charge at. Sure, you can get the charge rate down from the 1C (1 hour) historically safe to 3C (20 minutes) IF you've got a powerful enough charger but you WILL shorten the life of the pack. The newer cells on offer are capable of taking a higher charge rate but we're still nowhere near where we should be - just when are those hydrogen cells coming that we keep hearing about?? Just imagine the power required for such an act. A 12s 5000mAh pack at 1C charge will require over 200 watts of power to get it charged. The same pack at the 20 minute rate would take nearly 700 watts (nearly 3 amps of 240v mains supply) and generate a bunch of heat? Our 15S packs equate to 55.5v nominal 6000mAh (I'm guessing?) would need a power supply of a kilowatt to charge for 20 minutes, that's some big wires? In the RC world we're usually limited by a 12v leisure battery to charge from which sends the wattage even higher Estimates / dodgy calculations etc. cannot be relied on as the 'grey matter' ain't what it used to be feel free to correct where necessary?

Anyway, probably you can safely charge at 4 or 5 amps without any danger. Original charger uses 120w, which is between near 3 amps and 2 amps until achieve 63v. Then it enters in constant voltage mode. Link to comment Share on other sites More sharing options...

ninebot one p Posted November 20, 2015 Share Posted November 20, 2015 How would this work? Do you splice your ninebot one plug at the end of the out put cable. Link to comment Share on other sites More sharing options...
Cranium Posted November 20, 2015 Share Posted November 20, 2015 Some of the power supply sellers will allow you to specify what type of plug you need. The Ninebot One uses a LEMO 4 Pin connector. Or you can just buy the connector separately: http://www.aliexpress.com/item/LEMO-plug-self-locking-connector-PAG-M0-4GL-AC39V-PLG-M0-4GL-LV-glaze-concavity/32274404303.html?spm=2114.01020208.3.1.eoMCez&ws_ab_test=searchweb201556_2_79_78_77_80,searchweb201644_5,searchweb201560_9 Link to comment Share on other sites More sharing options...
