Timestamps
00:00 13s wiring for 7s-16s ANT BMS
00:10 connect B- wire and black balance lead to #1 cell negative
00:25 next attach white wires to cells #1-#7 positive terminal in order shown
00:37 for 13s configuration, ignore the last two white wires on the first harness
00:56 on the #7+ cell, you will connect two balance wires.
1:11 the second harness red wire and first white wire next to it are connected to the #13 positive terminal
1:34 attach all the wires in order shown, with the last wire going to #7 cell positive terminal
2:00 plug in both balance wire harnesses
2:19 plug in the wire connector with tiny red and black wire
2:24 using a 3-5v voltage source (such as a battery) momentarily connect black to negative and red to positive
3:42 if you hear a beep and see a tiny flashing light, the BMS Bluetooth is on and ready to connect
4:22 download the ANT BMS iOS app from the store
4:42 Open the ANT app
4:48 showing weird voltages because its set for 16s
4:56 click “parameters” at the bottom
5:03 click FastSettings
5:24 enter 12345678 as password
5:51 select battery chemistry so it presets all values for that type of
5:56 enter number of series for your battery and wiring
6:05 enter AH (AH per cell x number of cells in PARALLEL) in this case its 5ah x 1 cell = 5ah
6:26 the settings didn’t stick because Bluetooth connection was weak
7:43 reconnected and set 13s
7:58 all 13 series are reading correctly now
8:09 Vparameters (Voltage parameters) all set to default LiFePO4 values during FastSetting
8:15 unitOverVProtect set to 3.65v for LiFePO4
8:24 changed chemistry to Li-ION to show preset difference
8:30 now all voltage settings are for Li-ion chemistry.
8:51 back to LiFePO4 because my cell chemistry for this tutorial
9:03 notice cells are way out of balance and the BMS is doing nothing about it
9:19 go into balance parameters
9:24 UnitBalLimitV sets the maximum voltage for any cell and will bleed anything over this
9:33 set balance limit to 3.4 to show what happens
9:41 now the only cells over 3.4v are being bled down indicated by the highlighted cell
10:45 Pack Parameters: settings for your specific battery
11:00 here you can also set the current SOC voltage curve for your cells and ambient temperature
11:33 CurrentParameters where you can set all the critical current limits for your system
11:39 charging (and regen) limit and discharge limit are important to set for your controller settings
11:47 you can set these much higher than the BMS rating, so try to stay with the peak a rating or lower
12:26 an autobalance was initiated due to high cell difference , all green cells are being bled down.
12:47 temp change cell differential limit to 0.500v for demonstration
12:58 still autobalancing because ones it starts it has to complete or be stopped manually
13:03 i click Stop Autobalance
13:07 now only the cell over the balance limit setting (3.4v) is bleeding
14:00 bleed is only about 90ma so very slow
14:16 first balance can be sped up externally with a hobby charger to quickly charge or discharge individual bricks
15:19 I plug in charger. -1.9a shown in current meter
15:33 now many cells are over 3.4v balance limit so those all start bleeding down
16:06 the charge balance is also set at 3.4v so this will also trigger balancing
16:21 charger unplugged so current is 0.00
16:26 only cell #10 is over the balance limit and cell differential setting still too high for autobalance so only cell #10 bleed
What ant app are you using? Mine looks different. There are 3 different ant apps
Im using the latest iOS version normally, but I also have an older app no longer in the app store that works for read-only.
There are also many Android versions scattered around.
