not gonna lie, I didn't know the P pads could be used for both charging and output. I got to see if the current BMS I have now has compatible pads, Thanks!
What BMS is this btw? Is it the red board?
This is the BMS I drew in the picture. I have to find the datasheet for it since it's been a while. I believe the manufacturer is ACEIRMC
That BMS does not have handling for charge and play, and will require the use of an 8.4v li-ion smart charger. Does the USB-C PD device you plan to use have that capability? A BMS like that will not be able to charge the cells safely with just normal DC current.
I was going to be using this. But after checking to see if it is charge&play. I realized it can't even charge li-ion batteries. Do you have any recommendations on a good smart charger?
Any basic wall power 8.4v li-ion smart charger with a barrel jack will do. Otherwise there are USB-C modules like this one that claim to have smart charge capability, but I haven't seen anyone else use one yet and can't comment on reliability
Yeah just wire the barrel jack +/- to P+ and P- directly, and then use a latching switch on the positive wire between the system and the BMS to turn it on/off. The ground wire should be left connected at all times for safety reasons.
Awesome, thank you. I want to use a numeric LED display to show off the battery percentage left but I feel like I'd have to use a microcomputer to control all the LEDs. Maybe just using a 4 pined RGB LED would be easier.
Most digital li-ion fuel gauges you can buy off ebay/amazon have an integrated microcontroller and will just display information when powered
Word, I just recieved one from the mail and gonna test it out soon. Thanks!
Can I get the part number or link to buy this board and power supply? The board being most important. Thank you sooooooo much!!!!!!!!
