I bought an extra battery for elektrosamokata Segway Ninebot. Everything was not as good as expected.
Additional battery may be installed on scooters Ninebot ES1 and ES2 (the latter being converted to ES4). Battery doubles battery capacity and increases the maximum speed of from 20 to 25 km / h.
In all picture shows that the battery is mounted on an additional platform. I assumed that because of this the battery can be placed if necessary and shoot when it is not needed. It turned out that it is not. The platform is screwed on the 4 screws and the battery to it on the 2 screws.
Even if these screws with an uncomfortable head screws to unscrew and remove the battery, use the scooter without unscrewing the platform will not work - it closes a charging socket staff.
Battery weighs with a platform 1.6 kg.
When I installed the battery on the scooter, she refused to work (shows a connection error). I struggled with it a half-day was about sad carry back to the store until you update the firmware realized scooter. It was found that the battery was a new firmware, and an old scooter and they are not compatible. Who would have thought. :)
With the additional battery scooter can cover greater distances on a single charge. Maximum speed is increased only at maximum capacity "red S". In this mode, the motor current is much larger and the battery consumption is higher than in other modes. The forums write that were combustion controller scooter cases when operating in this mode and does not recommend its use.
It turns out that plus an extra battery only half. And there were many disadvantages:
1. The battery is very expensive - I bought it for 8990 rubles (Ali even more expensive). It housed 20 18650 Battery. Even expensive and branded batteries of this type costs about 170 rubles apiece, and those that are there are not more than 3000 rubles for all.
2. Very uncomfortable that the battery is not removable.
3. Worse, even removing the two screws, you can not use the scooter without a battery - charging connector is closed the battery mounting platform.
4. Charging connector is positioned so that it is impossible to charge the scooter in the folded state.
5. Though the battery and weighs 1.6 kg, the difference in weight _ochen_ felt.
6. Because the battery has shifted the center of gravity and the scooter is inconvenient to carry in folded condition on one wheel.
7. Wear it too inconvenient - have to take for the very end of the pipe and scooter outweigh.
8. Though Ninebot and firm, yet the battery in a plastic housing is potentially dangerous than the battery in a metal tube.
I'm your battery, perhaps, take off. I hope my experience will be useful naynbotovodam.
