I'm worried that I will explode my 4S4P battery pack in the back of my motorcycle!!!! Here's the details-
So I've built a 4S4P pack to power my CPAP machine while on a motorcycle camping trip. (I will be riding about 6-8 hrs a day)
Got it all Soldered and it's giving me 15.5V, which is good.
So I got it all connected to a cheap BMS I found on Amazon, and the output from that board is only 9.3V !!!!
So I completely disconnected the BMS board. I'm thinking of just connecting it directly to the bikes charging system via step up converter (dialing in 16.6V). This would be a steady voltage of 16.6V, and I could adjust the current too, (this board has 2 potentiometers- 1 for Voltage, and 1 for current) Not sure how much current would be optimum..
I was thinking of adding a small voltage meter and checking this periodically while I ride, so as not to over charge the battery- but I'm deathly afraid of a giant bomb going off in my rear case where the battery is housed..
Any help, or advise with this would be greatly appreciated.
