sorry about that, you can send it back for full refund.I don't have a lot of room in my batterycase but 10mm would probably work.
It's 13mm thick!!!! Doesn't fit. Why would you lie about that?
Some customers contacted you before about the wrong dimensions and you admitted it was incorrect but you still didn't change it on your page? False advertising!
Don't need to worry the AWG / wire gauge of Neptune 15, when compare to MOSFET's internal resistance, the wire gauge or wire's resistance can be ignored, most people concern improper use of wire gauge with high current can cause heat and even fire, on Neptune 15 the heat of wire can be dissipated via its heat sink. and the quality of silicon wire is fire-proof e.g. you can use lighter to burn and live monitor the FET Temperature value via Android client and see the max. temperature transfer with heat sink.Amp ratings? Almost no info on your webpage. In the user guide it says "DISCHARGE CURRENT RANGE 0 - 59.00A"
So I expect it to handle 50A. It comes with tiny 14AWG wires which are only rated to 15A.
So the 15 in "NEPTUNE 15" is the Amp rating? False advertising!
no, Neptune's power switch is used to shutdown the power-supply, one side is GROUND and other side is its Voltage regulator.electric_nz wrote: ↑Oct 22 2020 5:27pmDoes the Neptune BMS switch the negative terminal to the battery?
then the LED will stay ON whenever you switch ON / OFF Neptune.electric_nz wrote: ↑Oct 22 2020 5:27pmIf so I’ll run the LED +ve to the 3rd series battery and the LED -ve to the Neptune -ve output.
the only way is to extend the on-board LED outside but it's 3.3v onlyelectric_nz wrote: ↑Oct 23 2020 3:48amOk thanks. Is there any way to easily power lights from this bms?
can you show your Neptune 20 include the balance plug ?4r3st3r wrote: ↑Dec 13 2020 7:51amI have just wired up my Neptune 20, following the diagram in the manual. But, when I log into my app, it displays each cell as 0V, despite them all being ~3.7V when measured manually. What am I doing wrong?! I have attached a screenshot of what it looks like in the app.
Thanks!
try connect balance plug without main discharge wire and POWER reset system4r3st3r wrote: ↑Dec 13 2020 7:51amI have just wired up my Neptune 20, following the diagram in the manual.

I am using it in a 14S system, so I have changed the cell number to 14.
What does this mean? Which is the balance plug? How do I POWER reset the system?
Here is a photo of the battery pack with the wiring connected. I am using a 20->14 convertor supplied by you.
How do I power it off/on? The button you provided does not seem to do very much? But I think that is only for stopping / starting discharge maybe?
did you connect the POWER SWITCH ?
Hi Danny,
sorry wrong diagram, the POWER SWITCH port should be on the SPEED SENSOR port, we uploaded the wrong diagram.

Hi Danny,
I have got it to work now, I disconnected the button and then unplugged and replugged everything else and now the bars are displaying on the app, so perhaps the button is faulty? It doesn't matter as I don't intend to use it anyway?
Thanks so much for all your help!
I saw your Neptune's shrink plastic has been removed, can you tell me why ? what's wrong with the design ?
Sorry we don't know about ANT BMS's features and we believe features can be enhance via both software and firmware upgrade.cheeko wrote: ↑Dec 13 2020 6:02pmSo i just got email after 2 years the Netptune 20S is ready,
what are the real benifets im currently using a ANT BMS and i know somepeople say there crap but after 2 years not one cell is out and it runs perfect.
Only reason i can see to upgrade would be size of the unit.
Tell me some cool features please
Regards

If the wires are short, yes, it doesn't add much resistance, but i would not say that it can be ignored since it means that all other parts will heat up more and connectors could overheat and unsolder.speedict wrote: ↑Oct 16 2020 5:40amDon't need to worry the AWG / wire gauge of Neptune 15, when compare to MOSFET's internal resistance, the wire gauge or wire's resistance can be ignored, most people concern improper use of wire gauge with high current can cause heat and even fire, on Neptune 15 the heat of wire can be dissipated via its heat sink. and the quality of silicon wire is fire-proof e.g. you can use lighter to burn and live monitor the FET Temperature value via Android client and see the max. temperature transfer with heat sink.Amp ratings?

you can compare with speed controller 3 phase wire's gauge#, motor 3 phase gauge#, it should use 12 AWG for 100A as well right ?madin88 wrote: ↑Feb 02 2021 7:28am

14AWG is definitely to small for a 60A rating and it was right and necessary to use 12AWG
the POS(+) internally connected to Neg(-) with TVS_Diode, it can be bypassed, but why bypass ?madin88 wrote: ↑Feb 02 2021 7:28amIt looks like Pos (+) and Neg (-) wires are going to the BMS and away from it. Is the Pos (+) wire necesssary for the BMS to work, or can it be baypassed (as with standard BMS)?
If i order more than one BMS, would i have to order also the firmware for each?
Will there be support for iOS in future?
no schedule yet.
Yes how true! would say it only works because for the most part these cables are located outside of the frame and have enough airflow.speedict wrote: ↑Feb 02 2021 8:11amyou can compare with speed controller 3 phase wire's gauge#, motor 3 phase gauge#, it should use 12 AWG for 100A as well right ?
if connectors is overheated and melt solder down (~130C) then the speed controller's switching MOSFETs should already been damaged, or the bad contact of connector caused.
Ok thanks for the infos. Because it would make assembly of ebike batteries easier.the POS(+) internally connected to Neg(-) with TVS_Diode, it can be bypassed, but why bypass ?
