I understand I can balance charge at a rating determined by the MWH

eg. 5000mwh = 5A maximum charge rate

Whats the rule therefore for things like fast charging? Avoid at all costs? Run at a lower rate?
heres an example..........

7.4v = 2S

5400mah = 5.4 amps (1C rate)

never charge above a 1C rate (as above)

never charge above 8.4v

never discharge below 3.0v (per cell)

some say manufacturers state on newer LiPos a minimum of 3.2v per cell

most if not all manufacturers say to always balance charge your LiPos

so using the example above, set charger to.........

LiPo

7.4v or 2S

maximum rate 5.4 amps (can charge at lower rate but will take longer)

balance charge

then start charging

Always use a LiPo sack and never leave unattended !!!



ps check out youtube for over charged and/or over discharged LiPo batteries to explain the last sentence............
