RE: Charging 5S from 12V DC input
The Manual says:
"Notes about charging LiPo, Li-Ion, and LiFe batteries:
• TritonEQ automatically sets the charge current based on the battery’s 1C rating. For example, if a capacity of 600mAh is entered
TritonEQ will set the charge current at 0.6A (600mA). For a capacity setting of 2500mAh, the charge current will be set to 2.5A
(2500mA), etc.
• For lithium based batteries rated at 11.1V or greater, the actual amount of current delivered to the battery might be reduced due
to the charger’s maximum power limitation rating. Various circumstances such as battery condition, low input power, etc. can
contribute to such a condition. This is normal."
Then, if using 5S batteries, better having 3 or 4 batteries charged at home. Or wait for 2 hours for charging at the field.[&o]
