Daly BMS and BT dongles

Hi All
Compliments of the season to everyone!

Is there an reliable seller of the DALY BMS in SA? needs to have bluetooth, etc.
Bluetooth dongles? Recommendations and sellers?

Related to this question… A BMS for a lithium Golf Cart conversion. What sort of amperage does it need to support…?


The only local Daly supplier that I know off is https://lithiumbatteriessa.co.za/collections/bms
But as far as I know Daly BMS do not use bluetooth. Their Smart BMS is with serial comms to an inverter.

The ANT BMS or the LTT/JBD Smart BMS do have bluetooth. The LTT/JBD apps are originally for e-bikes/scooters/carts, so it has a distance left option in the app (the default), or just a charge left option. I’n not sure how the ANT does.

As for the amps required you will have to look at the specs for the motor. A smaller BMS will still work, but will have a lower top speed.

Thanks Louis!

I am just giving some thought to the process and parts…
What BMS do you recommend? LTT/JBD Smart BMS with bluetooth?


This is the BMS that both @TheTerribleTriplet and I have. You can check his thread about it for more details. It is a very nice BMS and I have written a driver to connect it to a Victron system (there is also a thread for that) so it talks to it similar to an expensive battery like the Pylontech. It is also sold in the USA as a Overkill Solar BMS.

Where are you guys sourcing them? What price?

I am following the thread - so now want to play :wink:

I use this LLT model (and the seller) https://www.aliexpress.com/item/32954859072.html?spm=a2g0s.9042311.0.0.71994c4dl1ym11

You can get the JBD versions here https://www.alibaba.com/product-detail/Sales-promotion-smart-7S-24V-10s_1600127268513.html?spm=a2700.icbuShop.74.1.68c4fea4znlE6o
From the information we have it seems that JBD is the manufacturer and LLT is the authorised reseller.

There are many models. Choose the one that fits your needs best.
Just make sure it is a smart model and that the app looks like the one in my post (it should - but then you are guaranteed it will work). They all come with the bluetooth module that is connected to a UART (RS232). The easiest is to get one that also support a RS485 port (easiest is also to get the PC USB cable from them). Then you can connect the bluetooth and to the driver/PC at the same time.

Are you going to use it with Victron, @JohanB bought a Battery from Baine, and it was literally plug and play with Victron. I am not sure what you want to do, but the smart BMS in his new batteries seems to be work quite nice.

Probably not yet… just learning.
I have a Cerbo so not going to fiddle with my 48V system.
