24V 8S BMS with Bluetooth

Hi all!

I just ordered 8pcs LiFePO4 Cells 3.2v 200ah from RJ Energy to build my own 24V200Ah battery, but they didn't have a BMS with Bluetooth in stock.

Can anyone recommend a good BMS with Bluetooth and low temp cut off?

Hey Alexander, did you order these direct from the RJ Energy site or through Aliexpress? I like that they have all sorts of Ah ratings available, requesting a price via their website for 120 Ah cells now. Seems like the aluminum terminals are small and weak, anyone else had issue with this? I'm sure they're trying to make them light as possible..

Hey @Fish Freak I ordered these directly from RJ Energy, contact Carl Wu sales7@rj-lithium.com, he has been very helpful. I don't know if shipping to the US is working now, but they took under a week to Norway.
 
Is that what's happening for everywhere now or just Malaysia? Are they shipping from China to US now to, anyone know?

Singapore and Malaysia are essentially banning travel... Not sure about other nations... China is still shipping stuff to me though...

Damnit I hate these cryptic replies that MAKE you wait a little longer, and if you say you can't say and in the same sentence say 'low temp cutoff', I KNOW you're talkin' about WILL :) !!
 
I could tell but then I'd have to kill you. =P actually i just ordered this bms, will recommended it wills video , will work on 24v and 48v

It seems to me that many people just do not understand hat there are many types of BMS' out there with different features, functions, capabilities & complexities. There are also HUGE differences between them all, there is no single or "couple" of choices to pick from.

Take a look at TinyBMS which has all the goodies, is premium capable and another completely different animal that would work well... I was tossed up between this and the Chargery, went with charger but it was close.
Wow! Nice reference. Might point out, however, one conspicuous omission. This BMS. And it would tick all the boxes for a "Digital Protector" in that first table. Cheaper than any of the others in any of the categories listed as well (except the Perkins ... also Open Source), not to mention, comes w stellar support. Only limitation is 8S max but can handle up to 750A system (a shunt measuring limitation).
