I'm using JBD BMS with Bluetooth & balancing. So far, I'm happy with them. In addition to these marine batteries, I also built a 48v (16s - 105ah) battery for my golf cart. It's using a JBD BMS from the start and have had no issues. It's a 250 amp BMS and has done a great job of balancing as...

The charge current was 25 amps, 14.6 volts. I watched it and the JBD BMS did bleed down the two cells to get them into balance prior to charging. The current balance settings are set at Start Voltage 3.3v and the delta to balance is .15v (15 mV). Max voltage is 3.65 and I have them set to...

Just a quick update on my situation. I went through my cells and individually charged them to 3.65, most all of them dropped to around 3.45-3.49 afterwards. After putting a load on them for a bit and getting them down about 10% I plugged the charger back in. I noticed that while the DALY BMS...

Thank you very much for all the info, I was not aware that I needed to parallel all of the cells. I thought if I individually charged each cell to 3.65 they would be good. I'll get to work on doing this and report back after I verify all the cells are top balanced correctly. I'm assuming if I...

Thanks for responding. I did top balance each sell individually when I built them originally. Although the BMS has an active balancer, I do notice that the first cell in the pack on the cranking battery is always higher than the other cells. It's also the cell that trips the over voltage alarm...

Does anyone know of a German made BMS system? Talking with an engineer at a particular battery company he told me that they stopped working with all the China made BMS systems and have switched to a German made BMS that has been flawless. Unfortunately, he would not give me any other information...

Just adding the info about the "Power-On Sequence" that EZGO RXV carts perform when the key is turned on. I believe the very first test when the motor tries perform the 1/4 turn in both directions is when my BMS is failing. Understanding the Power-up Sequence The car will perform the...

This comment was posted on another page in regards to my issue... I think this start-up sequence may be on the right track. As I mentioned before, everything is on and working, full connection via BT app and SOC meter working until I turn the key. When everything works properly you will hear a...

Super nice build! Thanks for sharing. Any issues with the JBD BMS? How is the Bluetooth app? I built a 48v pack for my EZGO RXV with a 250amp Daly BMS and thinking of switching over to the JBD. Thanks, Josh B.

In regards to the overcurrent protect, I just manually set the value to 350A through the bluetooth app. I wasn't exactly sure if that value was for continuous or "peak". I had read from others that the max this motor/controller would pull could be 350 amps momentarily during a full throttle...

Thanks for the reply. The cutout isn't when I'm running the cart, not even pressing the gas pedal... just turning the key to the "on" position. My SOC meter shows perfectly on the dash, when it cuts out the meter shuts completely off and zero output from the BMS. Once it's on, I can run the...

Long post here, but need some help with my Daly 250amp BMS that’s randomly dropping output only when key is turned on. This is being used in my Golf Cart & I tried to include all the details below. Cart: 2015 EZGO RXV Controller: Stock Curtis 235 amp with programming to 30 Mph Cells: 105ah...
