Hi all it been long time in 1 year i need new pack.


I love small size this bms . Are they sill the best ?

my neptune 15 so far working great !

So I'll be applying 53.6v at 2 amps to the charge leads? you should use 54.6v CC/CV charger because 13s * 4.2v = 54.6v, if your charger output 53.6v it's mean 53.6v / 13 cell = 4.12v fully charge to each cell, whether your charger is CC/CV type or not, cell will be charged up to ~4.1v, but it won't...

some people use Neptune 15 to charge cell up to 4.1v to prolong battery.

remember port status upload here, see if i can interpret it, or send direct to Speedict support.

Too late, I have already spent way too much time on this, and I certainly won't disassemble my customers bike again. My plan was to sell bikes with speedicts but the errors and lack of support have made me search for another solution, which I found a long time ago already. Oh sorry, my point is as ...

I forgot to mention : -In Road legal 2 mode, now and then suddenly it accelerates full power 15A without any reason. -When using the "instant legal" shortcut on the phone, all settings of the Speedict get erased and my bike won't work before I set everything up again (wheel in the air for...

the Neptune lite sounds interesting and i would like to experiment with it. Anybody know where i can buy the JST PH 2.0mm female 15 pin connector plug w/wire ? That is what i would need to connect my 15s lipos to the board right? best i could find was a 12 pin http://g01.a.alicdn.com/kf/HTB1k3MxHVX...

My mercury is ok, i spent a lot of time to fine tune it.

I thought the upper limit was 13S?

the last diagram was misleading, this is the another one i capture from user guide, it support multi-cell via wiring scheme.

yes, now not fixed to 13 cells, just downloaded the user guide the multi-cell support via different wiring scheme.

It sounds likes it's not suitable for my kW fast charging requirements, where balancing currents could be much higher. as per danny...

Hello Speedict I would like to buy your new product. Have few questions 1. When you starting to ship? 2. I dont see energy consumption per km also no estimated range. How come? I think this is the most usefull info for mist users. Will you plan to implement also these function? (Is it possible to a...

Any chance of answering these questions- Is there an operating manual? What is the maximum through current? and the maximum cell balancing current? are the cell voltages programmable, eg like 3.60V instead of 3.65V for Lifepo4 ? I don't think danny has time to answer here, as per their information ...

Speedict has launched new product, which is BMS ? able to live view 13 multi-chemistry battery cells + balance, support both iOS and Android now ...

Speedict new product ?

Looking through the main Speedict thread, there are a couple things that concern me that maybe you could address. First, it sounds like the data download time is really slow, like 20 minutes. Has this been improved? Also, there were some problems with inrush current damaging the device; any comment...

good to heard that someone put Speedict client on wearable !

Sorry I only read first 11 odd pages soo far ... *edit* ok spent 5 hrs reading thread / watching speedict vid clips now #1 when will USB phone charge version be released #2 when will BMS individual cell logging be released ( not really interestd in it but saw talk of it and no further details since...

Thanks for your answer, Rosich. I will measure the throttle signal soon , hoping it's 5 Volt. But you never know, it's a very old (>20years?) construction, so perhaps not a throttle with a hall element. I think the twistgrip is of the wire-wound resistor type, I am not sure. Nowadays hall sensors a...

This sounds superb, much more integrated functionality than anything else I've ever heard off. Do you have a list of the actual specifications? When is it available, pricing? copy it from speedict facebook post 01. 12 cells Li-ion, LiFePo4 cell protector 02. upgradeable up to 16s Li-ion or 20s Life...

Question about the Speedict Mercury. I have a (chopper) bike with a 36 V- 350 Watt brushed DC motor (Angel brand). Sadly these bike is not road legal in the Netherlands, it has no PAS sensor, only a throttle (variable resistor twist grip). The controller has a main current input and also the 3 wire...
