Charge them at the rate recommended by the lipo manufacturer, historically this was always 1C or 1 x pack capacity in Ah ...so 5000mAh would charge at 5000mA (5A) and 350mAh would charge at 350mA (0.35A) |

its a peak charger, press go and wait. aslong as its all set corectly (5amp 2s/7,4v for your 5000mah 2s pack) it'll stop charging when its full, I dont know of a timed lipo charger (like the oldschool crank up charger and charge for X amount of time for X amount of capacity) you defenatly don't want to charge those 350mah packs at 5 amps, thats insane. ManxCrawler got it, .35a (sounds like you need to read some manuals, even the stickers on the lipo's themselves will tell you how many amps to charge them at) usualy it says "charge at 1c" wich is 1 times the capacity so your 5000mah gets charged at 5000mah (or 5 amps) 350mah gets charged at 350mah (.35 amps) many many many threads covering this on EVERY RC forum. |

The peak charger will charge the appropriate amount of time. Peaked a lipo will be 4.2v per cell. At a 1c charge rate a lipo will take approximately 1 hour to charge. So a 5000mah pack at 5 amps will take 1 hour. Of course the charger is limited by it's out put watt capability too. So id you have a 50 watt charger it will only charge at a max of 50 watts which is amps/volts. For your 2s 5000mah pack you are fine but on if the pack was 3s you wouldn't charge at 5 amps but closer to 4 amps. |

A "wall wart" charger may take a lot longer, since it can't balance charge, you run the risk of killing a cell. Have more questions, please ask here. | |

If it doesn't hit the voltage within a specified time, it may time out (usually 120 minutes/2 hours). This is either due to a low rate/amp setting or a pack issue. | |
