Going to rework this so I don't need the buck converter . Seems or I replace the buck converter with a buck/boost converter.
At present it doesn't seem like it is not charging to full currently capacity with the buck converter. Could also just be the battery level monitor. We shall see.
BMS
Previously I had used the following BMS which has separate charge and power connections with a large input voltage. This bms will allow me to remove the buck converter. I will however have to reconfigure my battery to a 2S3P configuration which I had previously believed was an issue....
2S 2-3A 5-8.4V Red
Size: 62 x 26 x 6.9mm
Charging Voltage range: 8.40-8.45V ± 0.05V
Over-discharge Voltage range: 4.6-5.1V ± 0.05V
Maximum operating current: 2-3A
Maximum instantaneous current: 4-6A
Working temperature: -40 ~ +50°C
Resistance: less than 45mΩ
