Hi Ross really love the design of your system. I want to source the BMS’s you have used and would like to communicate further. Any help would be appreciated.

Hello Ross, I am not sure to understand why you have 2 BMS system ? the DIYBMS (round pcb) + the tower? Am I right ? I would like to understand which one is balancing the cells, the tower ? The round pcb are just for controlling the cells maybe ? Thanks for your answer

Hi Quentin, I have since changed things, I have done away with the BMS tower and now running with the round BMS boards along with an upgraded controller for the round BMS boards from Stuart Pittaway, I have also installed a "TOP BMS" ( similar to a Daly BMS) that has Bluetooth, this allows me to disconnect on the negative side of the battery if there is a problem that might popup

community.openenergymonitor.org/t/re-diybms-for-lithium-titanate-battery-cells-lto/16310. there is 3 files together, only use the first two, ModuleV421_Round_bom_jlc.csv (882 Bytes) ModuleV421_Round_cpl_jlc.csv (1.9 KB) then a few post below take the gerber zip file (65.9 KB)that has the 12.5mm hole centre, the gerber that is listed with the 3 files has a larger hole centre which is too large Here is another link if that doesn't work 1drv.ms/f/s!AobCW_rM88t-snaLWBO1MA08ZHUO
