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!
sorry about that, you can send it back for full refund.

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!
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.

Hi, I have a Neptune 15 and was wanting to connect a 12V flashing red LED rear so that it switches on with the power switch.

Does the Neptune BMS switch the negative terminal to the battery?

If so I’ll run the LED +ve to the 3rd series battery and the LED -ve to the Neptune -ve output.

Any issues with this? Thanks

no, Neptune's power switch is used to shutdown the power-supply, one side is GROUND and other side is its Voltage regulator.

then the LED will stay ON whenever you switch ON / OFF Neptune.

Ok thanks. Is there any way to easily power lights from this bms?

For my 20c I'd say just get yourself a little 12v buck converter. Current requirements would be super minimal for a light and maybe a few accessories. Probably the easiest way around it all. Then you can just run it straight from the main wiring harness, no need to tap into the BMS etc.

the only way is to extend the on-board LED outside but it's 3.3v only

I 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!

why display only 14 cells (RED bar, even it's not shown) ?
Check OOPTION-> DEVICE -> CELL #
and make sure Android client is for Neptune 20

I am using it in a 14S system, so I have changed the cell number to 14.
I have tried with Neptune 20 and Neptune 20 Lite clients, and neither displays the bars.

Here is a photo of the battery pack with the wiring connected. I am using a 20->14 convertor supplied by you.

Thank you for your help! I am sure it is something I am doing wrong!

i mean connect the 2 x 11 pins balance plug / connector to Neptune 20 first, and then power off the Neptune 20 and power on again, you should see 4 LEDs either stay ON or flashing, 1 x GREEN, 1 x RED and 2 x BLUE LEDs.

how's the 4 LEDs status ?

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?

The LEDs are as so:
Blue: ON
Blue: ON
Red: Flashing every second
Green: ON when connected to app

power switch is for turn on and off Neptune 20 or use to reset the system

if you can see 4 LEDs either flashing or stay ON that's mean hardware look normal.

can you show me your OPTION -> DEVICE page setting ?

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!

sorry wrong diagram, the POWER SWITCH port should be on the SPEED SENSOR port, we uploaded the wrong diagram.

excellent !

not because of the button, it's plug into wrong port with our wrong diagram, tomorrow we will upload the correct version, sorry about this.

So 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

Sorry we don't know about ANT BMS's features and we believe features can be enhance via both software and firmware upgrade.
Most of our efforts were spent on hardware design such as size, hardware feature such as power take from top (highest) cell not other e.g. cell #3 to prevent long-term cell imbalance (I am not sure other BMS also take power from highest cell).

wow, looking so awesome. new design looks really stealthy and cool. both Neptunes (15 & 20) have now 12AWG so I don't have to solder my own wires anymore (old versions had only 14AWG original). heat sink looks very different and no srews anymore that protrude - i like details. it is a pity that the BMS will be hidden in my batteries :lol:

If there would be a beauty contest for BMS Neptune would win ! at any category ! and of course against the ANT BMS :lol:

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.
14AWG is definitely to small for a 60A rating and it was right and necessary to use 12AWG :thumb:


It 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?

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 ?
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.
we did experiment by using lighter to burn the wire for 1 minute and live view its temperature as the result just raised around ~3C degree
anyway we already upgraded AWG12 on both NEPTUNE 20 and 15 for customer feel comfortable, for NEPTUNE 10 we still use AWG14 without any issues for skateboard application.

the POS(+) internally connected to Neg(-) with TVS_Diode, it can be bypassed, but why bypass ?
each NEPTUNE purchase must include 1 x HW and 1 x FW, the reason we split into FW and HW is because of import tax declare on shipping invoice.

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.
The problems are the connectors. If an ebike battery has been installed 100x it's contacts might wear out and the resistance increases, and big wires help to keep them cool and usable instead of adding additional heat :wink:

Ok thanks for the infos. Because it would make assembly of ebike batteries easier.
