Re: ABS for QMX+. Battery/charger design improvements over version 1.1 #PSU #QMXplus #ABS


 

Looks like I have found a workable solution:
?
?
Two issues here:
?
1. MAX745 multi cell lithium battery charging board - not sold in Amazon. Only available through eBay and aliexpress with long delivery time.
2. I had a brief email exchange with Hans. The booster might (will?) create noise (RFI?). So, this will need to be tested.
3. Diode for circuit separation is OK, but relay is better.
4. Adding all these together along with BMS will inflate the total cost for the battery charging.
?
Any thoughts?
