Hi,
I am planning on buying the the 10s4p battery from enertion that is is in the Raptor2, the Enertion Spacecell Elite, that is made of Samsung Q30 cells. I want to use it in a DIY Project and look for a BMS.
-How would the battery be connected to the BMS?
-on the website it says that certain parameters of the BMS are adjustable. How are they adjusted?
-Is there a better BMS that I could use?
This is going to be my first build and I have little to no experience with batteries.
The connector on the space cell will not fit the Bestech 10s bms.
The bms comes with a cable/connector set
You will need to remove the balance connector from the battery and splice in the cables that come with the Bestech.
Be careful to snip the balance wires one at a time and don’t strip them until your ready to splice them. Then do one wire at a time.
You can easily identify each wire with a voltage meter.
Connect the black ground probe to the Black main wire of the battery then check each pin with the red probe.
The pin with the lowest voltage is cell 1. the pin with the highest voltage is cell 10.
Cell 1 and 10 will be on the outer edges of the connector. The rest will be in numerical order on the connector.
Best to start with pin for cell 1, snip it’s wire and splice it to the wire that goes to pin 1 on the bestech bms and work up in numerical order from there, pin 2,3,4,5,6,7,8 9,10
The Bestech 10s bms comes with two cable sets, 1 with 8 pins for cells 1-8 and 1 with 2 pins for cells 9 and 10.
I have been using this particular bms for over a year on 2 builds and they have been rock solid.
They are very robust.
It is highly recommended that you use some type of static protection while handling the bms.
I use a wireless anti-static wrist band that absorbs any static build up.
Cool, thank you very much. On the website it says parameters like the overcharge protection und Overcharge release voltage are adjustable. How are the adjusted? And it seems the minimum I can buy is 2 units? Did you get your BMSs from thier site too or is there another site I can buy it from?
I bought mine directly from Bestech. The settings are adjustable at the factory so you have to request any changes during the ordering process.
I don’t know of any vendors for these.
The min order is two.
I have ordered at least 8 of them, 2 of which are on my 2 builds and all the rest I sold on this forum except for 1 that I got for a local skater.
Whilst that is indeed true, you needn’t cut the wires off the BMS’ to resolder them if JST connector is of the same family as the one on the Enertion pack.
You can simply pop the pins out of the male connector (female pins) on the space cell and pop them in to the one that comes with the BMS…
I own a Raptor2 but I am not shure if they make thier own BMS.
The BMS they use is very small, its the circuit below the display (this is the best Picture I have right now)
That is a good idea as long as they are the same size.
I’ve been at Fry’s electronics and seen several tools that they sell for removing the pins.
I think it would be well worth having the tool.

I doubt enertion make it,too time consuming,if you can find the serial number/model number then your on to a winner,post it here if you do,it will help others out!
Ok, so I have opened it up again and I believe the BMS used is a BWPB-277. The problem is, my chinese is a little rusty So I don´t know if its worth the efford to get one of these. I found it nowhere else but on this site. If you have any ideas on how to get one please let me know. And if you know anyone who sells a single Bestech HCX-D223V1 please let me know as well since I can buy them only in batches of at least two from the manufacturer.
Hi. What are the exact specs on it? (I ask because on the datasheet they say that you can adjust certain paramaters). I live in Germany, would it be possible for you to send it here? How much do you want for it?
