0:00 Default settings always is for max series, 16s for the 7s-16s version.
0:10 its a hot mess right now because only 13s connected but its set for 16s default.
0:30 go to FastSettings and set correct series and AH, clicking “settings” afterwards. Then click battery chemistry type and then hit “SAVE”
0:45 first use you enter password 123456789abc
0:52 now we see everything looks ok now.
1:18 default balance settings will work for most batteries, but we can set them for better monitoring.
1:28 UnitDiffOffV tells the BMS when to stop balancing. It can be set for 0.000v difference.
1:50 it will not automatically balance unless 3 conditions exist.
2:18 ChargingUnitBalStartV is the minimum voltage before autobalance can automatically start. Let’s set it to 3.8v for now.
2:30 once battery voltage, voltage differential, and charge current conditions are met, 60 seconds later it will automatically begin balancing
3:26 autobalance has been initiated. The ANT waits to allow the cells time to get to resting voltage.
3:35 the ANT uses passive balancing, which is sufficient for a healthy battery properly matched.
3:50 the green cell groups are being bleed through load resistors to bring them down to match the lowest cell.
4:00 some BMS use active balance, which transfers energy from the higher cells, into a capacitor, then dumps it into the lower cells.
4:10 If your battery is 💩 then you need an Active Balancer. But a good battery with passive balance is better.
4:19 we do not want autobalance starting on its own or it will mask any problems. So I set start Diff to 0.500v
4:58 UnitBalanceLimitV is an overflow setting. Any cell higher will bleed, so we set that high so it doesn’t ever bleed.
5:28 we will manually stop auto balance.
5:39 no more green lights. Balance stopped
5:43 now we manually start autobalance session
5:48 now it’s balancing down to 0.000v differential as long as battery is not charged or discharged, which interrupts it.
6:20 Voltage parameters are set according to your needs and your charger. It can be set 3.800v-4.350v max cell voltage. 3.8v for charging to storage voltage only.
6:58 recover voltage should be set slightly lower so charging can resume after you let it balance. But not so high it allows rhe charger to cycle on and off rapidly.
7:20 temps parameters can be set if you have the temp probes connected. Defaults cell overtemp is 60c but can be set 40c-80c
7:36 cold weather users need to set low temp settings for charging also according to cell datasheet
8:52 the current limits have a lot of flexibility so stay within reasonable amps and time limits.
9:03 this is a 180a BMS but I can set it for 600a. Not good because the temperature protection might not react in time.
9:12 these should be set mainly based on battery characteristics, DC power cable size, BMS rating
11:18 right now it thinks it has 71% SOC,
11:35 remaining AH just tells the BMS what your AH is initially, after that its not used. Let’s set it to 5ah.
11:43 it changes to 5AH (33%) then automatically calculates it from the SOC table and corrects it to 52%
12:18 these are the SOC calibration table. You can change these to match your cells and climate.
12:22 SOC Method 1 lets it automatically use the SOC table. SOC2 just uses electrons in minus electrons out
13:00 AH set to 0 so SOC os 0 and not automatically adjusting
13:28 AH set to 5 so SOC 33% (of the 15AH total capacity i entered in Fast Settings)
15:00 i think one of the SOC methods allows it to correct with a longer time delay.
18:37 systems parameters allows you to set when the bluetooth sleeps, and what will wake it up.
18:49 NoCurSleepTime is 1800 seconds default, but you can set it to 0 and it will stay awake always.
19:27 MOSFET overtemp can be set 40c to 85C. Colder gives more protection, but it can also shut down under normal riding if too low.
19:51 charge temp can be set lower. 45c is recommended. Release at 40C.
20:33 Balance charge current blocks balancing if over this limit. You don’t want to balance a difference caused by surge.
20:57 should be set to whatever current causes enough voltage surge to create a difference. About 10% of the AH should be ok.
