those look a lot like the motors that Torqueboards sells. If your gonna do a dual drive, get the 6355 If you gonna do a single drive, get the 6374
I just finished my 2nd build with the same battery setup.
Awesome!
I’m ordering more stuff tonight I hope.
so it looks like the main change is the voltmeter (little round thing?) and the other board (transmitter?) between bms and batteries?
Or are there some wiring changes too?
Where do I buy that bestech bms? Are there vendors on aliexpress?ms? Are there vendors on aliexpress?
the round thing is the power switch. the red square circuit board is the meter.
Alien Power systems used to sell Bestech BMS’s. Don’t know if they still do or have any in stock.
You can order directly from Bestech but they have a minimum 2 per order. The good news is that their delivery time is good and they accept PayPal.
Here is an example of total cost:
I’m thinking of ordering more boards so if you want, we could do a group buy. Assuming your in the USA
I might be interested in that depending on the timeline.
I can just add an extra to my order and hold it for you. I can cover the upfront cost
So you are ordering very soon? If so then I’m in
I’ll email my contact this weekend. and I’ll add 1 for you.
Just remembered its Chinese New Year so they might not get back to me right away. It’s worth the wait though. These BMS’s are much better than the stuff going on Ebay.

All good. I was just thinking about that today since I made a few orders from chinese companies. Bad timing. I just barely ordered the motor, vesc and batteries so I’ve already accepted that its going to be a few weeks before I have everything anyways.
also - question: I was reading about cell level fuses on the forum, do you think that’s worth the effort?
I don’t think it’s really necessary if your just building a battery for your own use. It’s a good idea if your building batteries to sell as a business. Are you gonna build a Li-ion pack or a Lipo system like what I have? I’ve built and used both and in my opinion the Lipo system is easier to build and maintain and delivers a lot more power than Li-ions pound for pound.
I just got an email from Bestech. Their factory is closed until February 6 for the new year
Yeah I’m going to follow your lipo build. Ordered the batteries last night
Good choice. Voltage sag is very minimal with this setup. Even when powering up hills.
What’s the cost on this BMS? I’m interested in getting one as well.
