A picture is worth a thousand words. Can't get it to turn on and give Bluetooth signal. Push button makes red light beep 3 times then shuts off for a while.

Once you have everything connected, Just charge the pack with 5-6V over the actual voltage and this will wake up the BMS with few beeps. Once stop beeping just disconnect the charger or lower the voltage. This will allow you to connect by Bluetooth.

Example. If you pack voltage is 60V rights now, set it to 65-66V.
 
My charger is set to 67.5 and mr battery is at 61.3. I tried hooking it up to the charger and turning it on. Same result

I cant see well but make sure you have the negative from the battery to B+ and the P+ to the negative from the charger. The positive straight from the battery to the charger. The last cable from the series also to the last cable of the BMS to positive as well. For example if you have a 16S configuration and the BMS is a 20S capable, make sure the B16 and B20 are in positive connected.
 
When charger is plugged in...it sparks unless I plug it in the wall last. But regardless ...the bms button won't do anything at all when it's on the charger. It only beeps on when it's off of it

When the BMS wakes up, will beep few times and will start flashing a red light. Then you can disconnect the charger and you should be able to access the BMS by BT.
 
If you see on my picture. I plug the charger on the end of the connector. The other one goes B- to the negative of my battery and the red goes straight to the + charger or the load.
 
buy one of the current DALY offerings and ignore the naysayers? 3 years on DALY now and once you get past the initial bullshit, they simply work. ever ask yourself why DALy has a huge heatsink?
