Id like to start a thread for orion bms users and for future users.

State the setup and share some settings and ideas to help myself and others improve the setup and SoC reading.
Some canbus settings and tips and tricks for relay setting to have an external battery heater etc.


My setup is:
Orion bms 2

Battery: 3 modules renault zoe gen 1.
3 modules in serie of total 100V
estimated around 70Ah . 2.8V-4.3V

If anyone have a good setup for Kia soul cell or others that are not included in orion setup please share.


I was trying to configure the SoC reading but charging the pack from a low voltage , 2.8 to 4.3, to max voltage with 1/3 C rate. 20A in my case. Continuing reading voltage value and Ah to try plot the charge curve.

One problem I noticed is that if you already have drift points set in orion the Ah meeter will adjust, drift, to accumulated Ah value and therefore adjust the SoC value on the fly. So theres no Ah meeter in background calculating the total Ah you charge with. So top tip to do this in the beginning is to have no SoC drift points when trying to plot the first charge and discharge curves.

The shunt capacity is pretty good for balancing. They state up to 200mA. I had a module out of balance before starting and had to leave it balancing for more then 20h for reaching withing 0.05V with the rest of the pack.

ill share some pics

I don't have anything to share yet, but I will be using an Orion2 with my electric racing kart. It will be monitoring a 42S10P 18650 pack combined with a Kelly KLS14401-8080IPS controller.

How do you like the BMS? For me it's oddly the least expensive one available, is supposed to have great support, and will easily support canbus controlled charging.

Nice setup you building, what are you expecting for power output and performance from the kart?

I can confirm the support is superb with fast answer and they understand easy what you are building or problems. For example they havnt got a plug and play for battery heating but they have a work around to control relay for a heater.

will be interesting to see in the future what they will add.

The first battery I'm building will have a usable capacity of 3.4 kWh. I'm expecting a possible peak power output of 55 kW (full beans with a fully charged battery for a very short time - for example, a drag race).

For a sprint race with B&S 206 karts, which is what I will be starting out with, it should be peaking at around 6 kW with an average of 4.2 kW over a lap, for up to 45 minutes per charge.

For a sprint race with 100cc karts it should be peaking at around 13.6 kW with an average of 9.5 kW over a lap, for up to 20 minutes per charge.
