Yes that's the best I have seen! :) I have to make a new battery for my golf standup scooterhttps://endless-sphere.com/forums/viewtopic.php?f=7&t=3573 My A123 LiFePO4 cells have about 3000 cycles 8) Please put me on the list for 1 unit, thanks!

I have found this in another post, it seems to be a feature of my controllers Is it possible to inactivate this feature?

Hello, dear forum members! I have the following problem: On my golf project vehicle I have two motors with 2 controllers from the company Freego Power Company (9 MOSFET, 36V-9M-3600-1) in parallel on one throttle running. At full throttle the two motors are going automaticly into cruise mode...

I have bought my speedict from Speedict Technology LTD. in Hong Kong and it was in use since 05/2011 and wanted to do a firmware upgrade, but this failed, now no firmware is installed. I also have tried to reinstall the last working firmware 2.0 but even this failed. :( Now, is it dead or what...

Hi, I have problems with the connection of the Celllog CMS/Balancer rev. 4.2.6 with the MeanWell Charge controller rev. 4.2.5. The Celllog CMS/Balancer tests are ok and I want to connect to the MW charger with the TPpacks Charge Controller. There is a two-wire HVC/optp output which I should...

Hi, I have found the error. It has been an interrupted trace on the second channel! Now everything is working! :D

no cells connected! Please check the voltages on this photo, I took it with the camera in a better resolution!

Hello! I hope somebody could help me with the problems I have, perhaps Fechter :cry: As you see on the photo the second channel does not work as it should. Only the second led is lit and the main led is red. But shorting the pin 7/8 of the optos it gets green. I have the meanwell plugged...

I too had problems with these single cell chargers. 4 out of 12 of these chargers made troubles and did not charge anymore, but I did not change the polarity. Some died on heat problems maybe, I don't know really. The last one was very curious, when I connected it directly to a multimeter it had...

I use these: https://s.p10.hostingprod.com/@www.voltphreaks.com/ssl/catalog/product_info.php?cPath=3&products_id=28 But they should not be used without a space between two or more of them, because of heat problems!

Yes, thank you Andy, this was my fault, now the BMS is working perfectly. First do all connections to the BMS an then connect the charger!

@fechter My BMS board is not permanently connected 1. the charger is off 2. connecting the multi-pin tap wires via one big connector (ok) 3. connecting the three powerpole connectors coming from the charger to the BMS board (ok) 4. connecting the batterypack main connector to the BMS board...

Good news! I am waiting for the new board because my v.2.3 makes big problems. I had this problem once before, but now it is even more stubborn than ever. Perhaps I connect the BMS to the batterypack in the wrong order? I am doing like this: First I connect the multi-pin connector to my 16s...

The first four units behave as they should do, with a voltage of 14V all four red leds lit. Possible there is a burnt trace or a bad transistor. Curios is , that applying 56V to the BMS (12s) all leds lit and the green led comes up.

Sorry I did not test it with the higher voltage before the shunt mod, so I cannot say if the max. current was 9,3A as it reads on the label of the PSU.
