jer Posted February 14, 2016 Share Posted February 14, 2016 I have seen a reference to a 240 Watt charger for Ninebot 1 e as an optional accessory. Does anyone have one and/or are they available ? This would be great for charging on the move at a cafe, bar etc, anywhere you can borrow a power socket for a while. Having owned one for a couple of weeks my main conclusion is it doesn't like going on low charge. Battery level indicator is very non linear Takes mud and water no problem. At the bottom of the web page is mention of the 240 watt supercharger http://www.ninebot.com/ninebot/NinebotOne/index.html Thanks Jer Link to comment Share on other sites More sharing options...

jer Posted February 24, 2016 Author Share Posted February 24, 2016 I think they exist in the manufacturers advertising, not in real. This led me to the next stage as I was wondering if chargers were available that could control charge rate and level, such as are available in remote control sports. This would enable batteries to be stored at roughly 50% charge and fully charged just before use. Lipos don't like being fully depleted or stored fully charged, so this is quite a handy feature. Alas I don't think such chargers are available. Revoelectrix who make the top dog chargers for radio control have no plans to make generic quality chargers for electric unicycles. Maybe someone know something more. Jer Link to comment Share on other sites More sharing options...

Easiest "Solution": You skip the 2nd phase of charging (saturation/constant Voltage phase) and stay with ~85% charge. @HJ found a charger here It has more or less the same casing and has written in the description: "Charge for Lithium Battery > 57.6V * (3.6V * 16S) Lithium battery > 59.2V * (3.7V * 16S) Lthium battery > 67.2V * (4.2V * 16S) Lithium battery > For 16S Li-ion / Li-Polymer Battery Packs" So could be, that you can choose one of the three voltages for charging (3,7V could be around 50% charge). But i did not see any switch/dial at the pictures - could also be, that you just can take a choice while ordering for one of the voltages? However - if you really want this option, you could modify the charger @Craniumfound and add some more trimming potentiometer and a switch to choose between different pre calibrated voltages(~charge percent) ... Or as easy solution, you take two of them - calibrate one for 50% and one for 100% Link to comment Share on other sites More sharing options...

Another option is the Charge Doctor V2. It allows you to cutoff charging when the battery reaches a specified charging current. http://hobby16.neowp.fr/2016/02/07/charge-doctor-v2-auto-shutdown-function/ Link to comment Share on other sites More sharing options...

Available here as well, unfortunately sold out.

SuperSport Posted February 26, 2016 Share Posted February 26, 2016 I know, not totally related, but sort of related. I've got one of these generic 75 watt inverters. For Kicks, I tried to charge my NineBot with it while I was driving using the original charger and it WORKS! I was surprised because this thing is only rated 75 watts. It's a way to top off while driving somewhere if needed. I only got 3% in about 5 minutes, so not fast, but it works. On a long drive, it would help.

I takes ca 1 hour, that's why I would prefer 240 watts to bring an emptish battery back to 100% I discovered that 90% indicated charge does not mean 90% actual range. ie I went from 100% to 30% on the out journey and 90% to 0% on the return trip over the same route This thing is a bloody pain to carry.

smallexis Posted July 26, 2017 Share Posted July 26, 2017 If the power of the original charger is 120W and can supply 1.9A, a supercharger with 250 W would be close to 4A. And for a 9B1 E + battery, it's a little bit more high to preserve the battery life. so have a look at : https://www.amazon.fr/dp/B0747XXD3C Link to comment Share on other sites More sharing options...
