As far as I know, the Aliexpress store I linked to is from the manufacturer. Their website: https://heltec-bms.com/
And yes, low temp cut-off works fine and is configurable.

8s or 16s?GOOD NEWS: Overkillsolar.com has it in stock
I always crimp them into a single 6ga copper lug.For the multiple 10AWG wires coming out to the Battery ground and the negative bus, do you put individual ring terminals on each wire, then stack them in the stud or do you create a single terminal?
I used a #4AWG Lug. It was a tight fit on the Tinned ends of the wire, and I had to file down a couple of high spots. I used a hydraulic crimper for it. If you want to lengthen the wire, Use a HD Butt Splice to #4AWG. I bought a small bag of heavy duty butt splices just for that. Then use heat shrink over the top of it.For the multiple 10AWG wires coming out to the Battery ground and the negative bus, do you put individual ring terminals on each wire, then stack them in the stud or do you create a single terminal?

That's the vendor that has notoriously had shipping and supply problems. There are other vendors of it.found what looks like a similar item on Aliexpress cheap BT BMS with low temp
thanks for the infoThat's the vendor that has notoriously had shipping and supply problems. There are other vendors of it.
I've placed 2 orders with them. The first one went off without a hitch. Second go around I ordered a bunch of stuff. It said it shipped and then the shipping was cancelled It took me a couple days for the seller to respond. They claimed that the shippment was too expensive and the package was returned to them, I asked for a new tracking number and they gave me the tracking number of my first order (insert eye roll). After pressuring them they shipped my stuff via DHL air and I got it all within a week.That's the vendor that has notoriously had shipping and supply problems. There are other vendors of it.
Normally it is recommended to use a charge booster (battery to battery charger) to charge using the vehicle alternator. If not, your alternator might be using itself 100% to try to charge the battery asap. Therefore they recommend a 30a charge booster (So that the battery charger at maximum 30a and not using the alternator for 100%).
Thanks for your reply but in my case it is a motorhome (so not a trailer) so then I guess I do need the DC-DC charger right?
Allright so I am thinking of ordering this BMS to work together with my 4*200ah cells.
I will be using it in a RV and it will charge through 300 watt victron mppt solar charger and through the vehicle alternator when driving.

Now my question is:
- Can you set the maximum charge rate on this BMS (using bluetooth).
If that would be possible, I guess the charge booster (in this case more limiter) is not needed. Am I right?
