Battery & Charger

The official battery has a flashing LED on the inside and a seal encircling the entire outline of the battery, 4-pin, she 4300mAh

The 100% load is when the charger turns green and the bars flash

When the bars do not flash but are all on there about 90-95% (it's safe for your battery life)

A little advice for battery & charge

When you load the MINI, the bars are all full, but they do not flashing, battery is charging around 85/90%.

This is a good charge level, to extend a Lithium Ion battery life

Of course, I also preferred to be fully loaded at 100% when the bars are flashing.

What I don't recommend is to charge the battery "hot", just after a ride, is not very good for the health of cells. I usually wait a half hour before recharging, the battery is "cold".

It's like a marshmallow, is deformed by taking in hand then it took to its original form, you can take a look, in app, the "remaining capacity", you will see that the level of battery increases when the mini is stationary.

Inside Battery by @Smallexis

SMALLEXIS is an active member in the forum URBAN360 Forum, you can also meet him in the ELECTRICUNICYCLE.ORG forum, it is an assembly expert batteries and BMS, a true genius !

He therefore remove the battery from Xiaomi MINI, and explains some interesting points.

Smallexis :

"The first step is to open the existing battery to see how it is made. But this time we must face the facts, NINEBOT set the bar high with a fairly complex BMS and industrial welds Points directly to the BMS.

So it is almost impossible to regain BMS for assembling the new cells. Anyway I do not venture me ........... sniff!

The grid that we can see is a protective grid, no ventilation because it is sealed with silicone.

I have shit to open the ABS case, but at least I saw what I wanted.

We better understand the presence on the implementation of the bookmark "BMS FIRMWARE VERSION" because it's a little more than a BMS is used.

I doubt that the Chinese copies battery can compete, so they will never be recognized by the app.

An original product NINEBOT must be compatible since it must use the same BMS on all mini version (single cell capacity change).

I have not yet closed the beast but it should be fine. I just have to find how to replace the silicone seal that left in tatters. "

Muchissima Gracias Amigo !

"Your Mini Pro beeps errors?

In order to understand their meanings, we must first count them.

Attention: the mini can emit long beeps followed by short beeps.

You will have to count the number of long beeps (which indicates the number of the tens) and the number of short beeps (which indicates the number of the units).

Examples:

9 short beeps indicate a problem "3", which means a CPU error.

3 long beeps followed by 4 short beeps indicate a "34" problem, which means a firmware update error.

TIPS FOR NEWBIES : CAUTION FOR REMOVING PADS

To newbies users this is an important tip :

When you clean your MINI, you can not remove and simply put back the pads.

Pads that are replaced from above are not properly replaced.

The plate, under the pads, which touches the joystick loses adhesion.

The result in driving can be disastrous.

The Mini no longer respond properly, no longer has the same responsiveness, driving is derived.

The Mini is the miniaturization of a PT-type Segway

All parts are nested to each other

If you remove the pads, you must replace them beginning with dismantling the bases of the pads.

There are several notches provided for inserting the pads.

Advice:

If you remove the pads easily, as I did, do not put them back by inserting them from above.

There are 3 notches inside, if they are not put back properly, the joystick, which normally adhere to the plate under the pads, are no longer in direct contact.

The Mini will deviate from his direction, contact foot / pad will be less reactive and, of course, dust and water are going to introduce.

After removing the pads, I put them back, foolishly on top, but it was not good, there are 3 notches inside, if they are not replaced correctly, the joystick, which normally adhere to the plate under the pads, are no longer in direct contact.

My mini deviated during a ride, the reactivity was not the same..

So watching the video tutorial of speedyfeet to disassemble and reassemble the pads, step by step, piece by piece, I had to dismantle and assemble all everything in order.

Remove Tire

How to prevent air leaks and punctures?

When using the Mini, the tire can leak air under the effect of weight and terrain

The tire is deflated and there are no traces of punctures

Using liquid silicone, it will "stick" the tire to the rim

The silicone is injected by unscrewing the valve from the valve

half a bottle of 125ml is enough

we screw again

we inflate the tire to the right pressure

It will surely be necessary to wait for the next shock that will let air out, then to inflate the tire again at the right pressure, so that the liquid "sticks" the tire to the rim, hardening

And in case of puncture, the liquid silicone will harden in contact with air
