A very common question you come across online is: Can you use an ES1, ES2 or ES4 battery in your E25
NineBot scooter? Well, the answer is “Yes”! You absolutely can, and it works well.
I filmed this as an installation guide and as a proof of concept that you can use these
external batteries in your NineBot . But, there's also a strong warning I need to share. Please,
do not follow these instructions until you watch the entire video. Okay, so down by the
charging part here there's your charging port, and there's a cover here. You just pry this off
just from the sides gently, and then under there, there will be two screws. There'll be one here,
and one here. You remove them and when you do, you remove the cover for the charger.
And then you remove the plastic here, and that's the port that your battery will plug into,
so the battery itself here comes with this metal piece. This is where the battery plugs
into your scooter, and this piece will screw into the battery like… so what we have to do
take this piece and affix it to the scooter on these holes here, and they line up: one,
two, three… with one, two, three. So after you remove those three screws from your scooter you
replace them with the three longer screws which come with the battery. So I've already taken
one of them and put them through the metal bar here, and I will line it up like so.
And, I will screw these in.
And what worked for me was the Torx T10. Okay, so after you get them the three screwed in here,
we're just going to take the battery and insert it. Line up the port on the battery
with the port on the scooter, and the holes here and here will line up with the posts here,
and here. Then, it's as simple as taking the longer screws and fixing the battery permanently.
And for these longer screws I needed the T15. I needed a longer bit as well,
a short little stubby bit like these bad boys won't reach far enough.
All right, so I got it on there, it's on there and give it a good tug make sure all
your connections are good… you don't want that to fall off while you're… while you're riding.
And you can see that it's got a full charge there, let's turn on the… all right it's good. It still
works so that's a that's a good plus. And, let's see what it says on our range… and look at that,
it just doubled my range to 44 kilometers. So that is great, it's exactly what you want to see.
Holy crap, am I happy I didn't upload that first part of the video yet! Here is a warning! Cruising
along this this shared use path here. This is a shared use path so I can ride on it. And then,
suddenly, look what is not on my NineBot! It was on here, everything was fine and then suddenly
is falls and it hits this latch. Which again is my fault… I should have had this up while I was
driving. But it hit it and that collapses, so this comes down, and of course you lose all steering. I
am so lucky. I was just on that main road over there, I would have nowhere to wipe out. Here,
I crashed on the on the grass I still got a pretty good knock. What happened?
The screws are still here, these haven't stripped, what's going on? Well, these things rotate!
They rotate in place! So for goodness sakes you have to use some Loctite!
The Loctite thread Locker when you put this on, because it just vibrated loose…
a little over a week later I'm still actually kind of sore from the crash. But
got it all taken apart again. So the issue is these screws here,
they rotate in place. They sure do. They didn't come with any locking washers or anything like
that, so we're gonna go ahead and use some thread Locker on these and re-attach this to the unit.
All right, so I've reattached it in the exact same way that I did before with the three screws
on the the mounting bracket and then the two in the battery itself. Now, these two didn't come
loose at all, it was the ones on the bracket. Those three on the interior that really caused
the problem. I'm going to get a strap or something as well to keep it on there, I'm very paranoid now
after falling. It was not a pleasant experience. And, of course, I was a fool for driving around
with this down I… it never caused a problem, until of course it did. So make sure you have that
locked up. If that was up and it fell here, far less chance that I would have had such a drastic
wipe out. Having said that, make sure you're using thread Locker when you're putting this
on because it's a big problem having that fall off in the middle of your ride. It’s
dangerous and a hazard, so learn from my mistakes, and from my accidents. And again, I'm just super
thankful that it didn't fall off where there was concrete all around me because… all it would take
is hitting hitting your body or your head on a curb and “lights out”. Like, it could really
cause some damage, so thank goodness! Lesson learned! Take the experiences that I had and
be safe! Enjoy your scooters everyone, take care!
