My 7th JKBMS and it works perfectly as it should. Service is great and personal.

I have ordered this BMS after not getting the desired functionality from other BMSs.
The decision was based on some YT reviews.
I was so impressed with the functionality that I ended up buying a second one and will buy more in time to change my existing 12v batteries as well...
Balancing works really effective! The app and available settings are excellent and you can fully set this BMS up to do exactly what you want.
The 6mm bolted connections are soooo nice and one of the key reasons why I bought the first one.
Service from Cell Supply SA was brilliant and prompt with both purchases. The type of service making you wanting to buy more products whether you need it or not!!!

Fast and efficient delivery.

BMS was easy to install and setup. Definitely worth the buy

I ordered more than 30 JK BMS from Cell Supply SA and the service is very good and fast. Dankie Darius vir jou tyd en is altyd behulpsaam.
The BMS is easy to install and works perfectly. I recommend this company and BMS.

After many years as a diy'er finally found a professional knowledgeable down to earth helpfull supplier . Guys 100% for you thanks for help you changed my outlook with this excellent lifepo4 and bms combination..

Great product , easy installation and Daruis goes above and beyond to assist with any quaries. I would recommend cell supply to anyone in need of cells.

Great Service ; same day delivery!, Good Products and well priced.

I have opened a lot of LIFO batteries and most of them had either 72 , 90 or 100 Amp hour cells, which is much too small for big loads. And their cycles are limited at 4 000 to 6 000. The 280 Amp hour cells is different ball game as you just need 16 of them to build a proper 48 Volt x 14,3 kWatt hour battery. With a 200 Amp JK BMS that has the convenience to programme the battery via Blue Tooth. Now you are able to discharge that battery at a maximum rate of 190 Amps and you have a JK BMS that are able to constantly balance the 16 cells. You are also able to build 24 Volt as well as 12 Volt or even 36 Volt batteries with these cells and you will be able to get 8 000 cycles out of them providing you are not over charging or under charging them.

Incredibly fast delivery.
Friendly professional service with sound advice.
Product working like a charm, first time.
What can I say but: 10/10
