Im going to make a big bms order with a company that I find very good, and reputable.
Maybe even more than Bestech which has been the standard for DIY electric skateboards.
One of my customers ordered their BMSs to me to install them in his batteries and when the package got stuck on the customs, a lady from their office in China called me on the phone to notify me and when the package came, they even send me some gifts
Their bmss are very small and all have really nice alu anodized heatsinks to help with the heat dissipation
And they can also come with mounting holes so you can bolt them down to your deck/enclosure
About dimensions, I will measure them tomorrow and post the exact dimensions of them since I don’t have my caliper with me now
Since I use a lot of bmss for my battery packs, and the BMS market is not really full of options Im thinking of starting a small BMS store
I would appreciate your opinion on them, and they as a company are willing to cooperate to make a bms suited for our needs, Im in no way affiliated by them or paid by them to advertise their products.
The prices should be around
10s 70A -50$
12s 70A -60$
10S 100A -100$
12s 100A -100$
10s 150A -140$
12s 150A -140$
This is just a thread to see the interest in them, Im not selling them so thats why its in the electronics section.
Charge only cheapest option
Charge only waterproof
Charge & Discharge 50A waterproof
Charge & Discharge 70A
Charge & Discharge 100+A

That was one of my first questions, they said that they do not have one developed, but the lady said that she will ask the engineers if its possible to implement one.
But a bird from Bestech told me that they are developing one ATM, I asked that around 3 months ago and asked again a few weeks ago but its still in development
Is there an option to have adjustable balance voltage? This is the main thing missing from the BMS market. What if I want to charge to 4.1V and balance at 4.1V? There is nothing on the market…
Almost all setting can be adjusted
I used to put that the balancing starts at 4.05V and the max voltage to 4.15V in my bestech GBs
But that would be needed to set in the factory, but if you want a bms that you can program i can send you an pm (xiaoxiaing bms or something like that)
I have been looking for a BMS with a simple bar graph display of each cell voltage.
I messaged you about these already didn’t know you started a thread.
Simple OLED display like bc-8s lipo monitor would be great.
I found the balance accuracy of these is ordinary. But ok for my needs they are pretty cheap from BG.
