  raspberry pi EP-0099 4 channel relay module schematic
Posted by: RustyOx - 30-06-2022, 04:46 PM - Forum: Rusty Ox - Replies (3)

I bought this for my home automation project, it is planned to be used to control siren and flashlight for my security system.

Board was bought from Amazon.

I noticed that the NC, NO is labelled wrong. The NC pin on board is actually normal open (NO).

It doesn't fit well on my Raspberry Pi 4 case, after cut some bits and drill a few holes ( for heat dissipation purpose), I have managed to put it in the Raspberry Pi case.

  BionX 40.8V (11S) system is working fine on 36V 10S battery
Posted by: RustyOx - 26-06-2022, 01:15 PM - Forum: Rusty Ox - No Replies

Before making my third pack of battery for my electric bike (Trek Ride+, BionX G1 I2C system, 4P11S 40.8V battery), I connected 1P10S 3aH battery and it works fine. 

The console shows battery level bar of about 2(I can't remember exactly bars as I forgot taking photos), internal diagnostic code (3772) shows message of low voltage, but using acceleration setting of 4, I rode about 7km with 3AH 10S battery. The ride assistant from the motor is good enough for me to ride comfortable.

It seems the console shows battery low as long as the battery pack voltage is below 39V, but it is still allows power to motor to assist the ride.

As it is 10S 36V battery, so don't expect big push as the 11S 40.8V battery.

Full charged 10S battery pack voltage: 4.2x10=42V
Empty 11S battery pack voltage: 3.0x11=33V

  ESXi 7.0U2 is not working properly with Windows 7 or Windows 10 VM
Posted by: RustyOx - 18-06-2022, 10:54 PM - Forum: Rusty Ox - No Replies

My Win7 Virtual Machine (VM) was working fine on ESXi 5.5, since upgrade to ESXi7.0U2, I can't register the VM, the task just going forever and don't allow me to cancel it.
Register Windows 10 VM is fine, but failed to power up.

I have spend nearly a day fighting with this issue without any success, I am going to try another ESXi version.

My currrent Version is ESXi-7.0U2a-17867351-standard.

  Third set of battery built for Trek Ride+ BionX Electric Bike
Posted by: RustyOx - 17-06-2022, 09:33 AM - Forum: Rusty Ox - No Replies

This is my third home made battery pack, (if count the original pack, it is the fourth pack of the bike.), It is use 44 (11S4P) Samsung INR18650MH1 battery.

I accidentally connect the battery wire in wrong direction and burn the XT60 connector immediately, fortunately the BMS seems survived, and ebike still working. It could be a very expensive mistake.

   

Three different battery used for my three set of battery pack. From top to bottom are LG HG2 (LGABHG21865), Samsung INR18650-35E and Samsung INR18650MH1

  Two set of battery Killed on BionX system
Posted by: RustyOx - 28-05-2022, 12:30 PM - Forum: Rusty Ox - No Replies

I just got two set of self-build battery pack killed by the BionX charger.

The first set is 11s4p with 48 x Samsung Samsung INR18650-35E 3450mAH battery.
The second pack is 11s2p with LG HG2  18650 3000mAH battery.

I believe both of them are killed by the charger.

To avoid fire risk, the battery charger is connected to a timed plug which will cut off the mains after a few hours. So the charger is not powered but still connected to the battery pack, so the charger is actually discharging the battery pack at slow rate without any protection, therefore over discharge the battery pack and finally killed it.

  The Trek E-bike Battery Pack was dead after not used during winter
Posted by: RustyOx - 30-04-2022, 10:33 AM - Forum: Rusty Ox - No Replies

My Trek e-book haven't been used during the winter, and I found it is not able to be turned on. 

The Battery Pack was built with Samsung 3345mAH 18650 8A battery about two years ago, now it is completely dead. It
 is measured only about 10V (norminal voltage is 40.7V for 11s battery pack) which means only 3 of 11s is working.

Most battery measured at 0V, few measured at negative voltage. The balance board is also burned.
