Pull on the connector with your other hand, not the wires. Next unplug the blue yellow and black wire (your may differ in colour). Remove the BMS and put the new one in, plug the power wires first :B- and P- then CH- and at last the white sense plug.

What to do if the battery is damaged by BMS?
For the BMS damage, the battery may work after replacing with a new BMS. Generally, we suggest measuring the voltages of the cable bus at the same time to check if any series of battery cells damaged or not. Measure the voltage of two adjacent cables, all the voltages should be the same with a small.
How do you fix a bad BMS?
This is called a hard reset and can possibly fix your BMS issue when sometimes a soft reset (jumpstart with a charger) failed!!! ALSO you need to test all the BMS sense wires, make sure they are all equal voltage (or close). Changing the BMS will not help a pack with a low voltage cell group.
What is an e-bike’s BMS?
BMS or Battery Management System is one of the essential components of an e-bike’s battery. It’s a small circuit board that stays inside the battery and ensures that the bike’s battery works appropriately and smoothly. However, sometimes you may face some battery issues like your e-bike’s battery isn’t charging or discharging.
What is the BMS of a battery pack?
The BMS — or Battery Management System — of a battery pack is the part that regulates both input (charging) and output (discharge) voltage and current from the cells.

How do I reset my BMS circuit?
Hold the wires just as they are for 15 seconds, and that should cause the BMS to reset itself. Once that's done, turn off the battery charger and remove the adapter. You can now check to see if the BMS allows the battery to charge and discharge as normal.

Does a BMS charge batteries?
Electric vehicle systems: energy recovery The BMS will also control the recharging of the battery by redirecting the recovered energy (i.e., from regenerative braking) back into the battery pack (typically composed of a number of battery modules, each composed of a number of cells).

Can I use lithium battery without BMS?
Well, actually, no – lithium batteries don't need a battery management system (BMS) to operate. You can connect a few lithium battery cells in series to make a battery pack without any sort of lithium battery management system, and it will be able to power various loads and be charged just fine.

Can I charge battery without BMS?
Using a lithium ion battery without BMS is not possible with safety. You can have one cell with overcharge protection. But 2 cell (7.4 V) or 3 cell (11.1 V) packs require a BMS to charge the battery fully without any problem.
Can I bypass the BMS for discharge?
You can bypass discharge and use the BMS for charging only. If you wire your BMS so it is only in use when charging your e-board, and gets bypassed when the batteries are being discharged, you can get away with this.
How do you wire a BMS?
For our BMSs, the second balance wire (the first thin red wire) will be connected to the positive terminal of the first cell group. Then the third balance wire connects to the positive terminal of the second cell group, and so on. The last balance wire should connect to the positive terminal of your last cell group.
Will a BMS balance cells?
When any one cell in the battery pack exceeds the Start Balancing voltage, the BMS will begin the balancing algorithm for all cells. The BMS will look for the lowest cell, then place a load on all cells which are more than the maximum difference in voltage above the lowest cell.

How do you wake up Daly BMS?
BMS should wake up with a load on the battery or a charge on the battery. There are also a couple pins on the BMS you can short to wake it up as well. I tried with a led or a heating resistance.
Is a BMS necessary?
The lithium-ion batteries can be used only in specified conditions, and therefore battery management system (BMS) is necessary in order to monitor battery state and ensure safety of operation. The different BMS structures have been compared and their advantages have been shown depending on battery system size.
What is a BMS failure?
Cell failure: Some of the cells inside the battery may have failed, or. BMS failure: The battery management system may not be operating. To get to the core of the problem, you have to test everything one by one. The first (and easiest) thing to test is the charger. You measure the output voltage.
What is the purpose of BMS in a bike battery?
The main role of the BMS in a e-bike's battery is to make sure all the cells of the battery are in balance during charging and discharging. "Cells" of a battery pack are actually cell blocks, made up of multiple 18650 cells in parallel (to give additional current capacity).
Can a BMS overcurrent protector trip?
If too much current is drawn it'll trip. The most common way in which a BMS over-current protector can trip is when they're charged from being completely flat.
Is BMS easy to get?
The good news is that BMS are easy to get online and not expensive. The bad news is that it can be a bit confusing which one to get! The most important part of a BMS is the size of battery pack it's rated for. You might know you have one of the following battery pack sizes: 24V, 36V, 48V, or 52V.

I've been a lurker for a long time around this website picking up what i can for my new love in the EUCs and i picked up a Zipwheel 16" as my first wheel back last year and have used it for about 5 miles daily up until last month when i was involved in a RTC with a speeding motorist i managed to get out the way but i was unable to get the wheel out in time and it was launched 15ft up the road cracking the case open and throwing the battery.
SinisterPrime
I appreciate your reply, the damage seems quite severe in the sense there is scorch marks but not knowing what its a part of circuit is damaged i didn't want to risk charging it.
SinisterPrime
Thank you very much your replies i have checked the cells around the outside and the whole thing was wrapped in plastic wrap then cardboard seems the out wrapping bore the worse of it but the BMS landed PCB down so took the damage.
custom battery
Hi all, I'm playing with the idea of building my own battery pack - as part of a plan to build a whole custom unicycle based on microworks parts (learning from lessons of others on this forum such as @DebboR http://forum.electricunicycle.org/topic/1881-another-30kmh-microworks-and-battery-upgrade/ or @mokwichi http://forum.electricunicycle.org/topic/2035-tg-f-5-500w-motor-upgrade/).

I thought 60v was pretty standard for these. Tomek's BMS has 59.2v which is weird.
9B Metrics
9BMetrics is an impressive IOS application developped by @Paco Gorina for the Ninebot One. It polls the unicycle to gather technical data (speed, current, voltage, pitch, roll, temperature) at a very fast rate (30 times per second) and stores them in files that you can display graphically on your IOS device or send to your PC for further analysis.

How to remove white wire from balance lead?
Start by removing the white sense wire plug (balance lead), do not pull on the wires but use a screw driver like this and try to move it a little and go to the order side and repeat. Pull on the connector with your other hand, not the wires. Next unplug the blue yellow and black wire (your may differ in colour).
Do you need to cut the temp sensor on a Luna BMS?
There is a temp sensor on all Luna BMS, so no need to cut or crimp just put it back were is was on the cells. First step is to unplug the big white sense plug then cut the wires one by one, tape over them so you won't create a short any were, remove the old BMS.
Is the BMS still made?
1) Your BMS is still made and it's plug and play (with bullet connectors on the 3 power wires) and the white sense plug with 10,13,14,15,16,20....wires and up is also the same. 2) Your BMS is still made but the power wires are soldered directly. 3) Your BMS is obsolete and the white sense plug does not fit....
Does a BMS have a B0 wire?

Does Sebz have quick connects?
Sebz. Your pack is a few months old and it does not have the quick connects. You have 2 options here, either you unsolder and resolder the wires on the BMS directly or you cut the wires and use a good quality butt splice and good quality crimper.

I have been having trouble with what the Evolve Service Team said is the BMS chip. My board shuts down very fast, it doesn´t changes to ECO when I go uphill. I bought a new motor controller but it didn´t help with the problem. Is somebody out there who knows what can I do to repair this BMS?
goodblake-eskate Member
So what is wrong with your bms? My board has an issue where it randomly shuts off typically when braking which I believe they said was a bms problem. I've sent in twice abt a year ago seems to be an issue still. Think it's bc it so hot here right now it causes the board to overheat since it didn't seem to be an issue in the cooler months
