You can connect negatives of both batteries and connect it to negative power supply on the
controller, and then the positives through the 3 position switch, so at one time only one battery is connected.
I dont understand everything, but one thing i can tell you for sure, batteries are not phisically connected through the original motherboard, there is some kind of electronic switch I guess.Dreadedb wrote: ↑Sun Mar 10, 2019 5:56 amHey all,Zik wrote: ↑Tue Dec 11, 2018 6:56 amYes in deed, I did found an abandoned Lime, looks like a ES2, don't have a external battery just a GPS module in front and this is the motherboard that I found.ZombieScoots wrote: ↑Mon Dec 10, 2018 7:26 amLooks like the ES4 has some new way of wiring that doesn’t fit the motherboard you purchased. So it definitely won’t be plug and play. But I’m sure a new clip can be added
1. Charging port
2. This is connected through the tube to the lower part of the scooter
3. Dashboard connection
4. Connection to battery
5. Goes down through the tube to the lower part of scooter passing by a long rail just in front of battery.
6. To battery
7. That cable was unplugged. I assume to connect directly to a kind of programing interface.
8. That cable goes to GPS module, I assume one of them brings the signal to the motherboard to turn on the scooter.
And this is the GPS moduleUserhost wrote:Anyone know how to open the plastic, rectangular Bird head unit non-destructively? I don't want to break anything, but I'm interested in seeing how these things work. The non-destructive part is important because I want to return this Bird to service once I'm done studying it.
Just opened
As you can see the circuit on the left holds the SIM card
Connection description
Pink arrow cable comes from motherboard.
Yellow cable it's the connection between that circuit and the big circuit to the left that holds the SIM card. I assume the white or the orange cable says to other circuit turn on the scooter.
The red arrow cable it's unplugged cable that I found in the back of module. I assume for programing.
So now I ask.
There's any way to replace the motherboard of this model? It's very different than the original one.
Or just run a jumper wires from one side to the other two complete connectivity and omit the SIM card entirely?
Been following this thread pretty closely, apologies if this has already been answered.
I've come across an es2 style lime identical to the original post. Ive got a replacement controller and display for it and all the color codes for the motor, hall sensor and throttle match so I'm pretty confident on wiring.
My question is about the battery and charging port wiring. The stock charging port has 2 pairs of red and black cables connected in parallel. With the original board, the pair with the white connector (4) go directly to the battery, and the pair with the black connector (not numbered in the picture) go directly to the board.
The controller I've got (generic in aluminum housing like many others) doesnt have the connector (black) for the 2nd pair of cables from the charge port.
Does anyone know if the black connector from the original board is simply parallel connected inside the original lime board to the main thicker battery input? Super easy to test but I don't have the lime board anymore.
My plan is to connect the thicker battery pair directly to the controller (6) , the 2nd thinner pair from battery would connect to the charge port (4). The black connector from the charge port wont be connected.
In short- because my controller doesnt have a power input directly from the charge port like the original board, can i charge from the original port via the white connector (4) and leave the 2nd pair open? The black connector enters the lime board really close to the thicker main battery input, but are they parallel connected?
Is connector 4 the recharge lead and connector 6 the discharge lead? Or is the mystery black connector in direct parallel with connector 6 acting as the recharge lead and connector 4 some type of balancing lead?
Probably overcomplicating things I just don't fully understand multi-cell lithium batteries.
