You can charge at 1 C. 1800 mah - 1C= 1.8amps. If it was a 2200mah it would be 2.2 amps.
However....Don't charge at 1 C. Instead of 1.8amps, charge at 1.5amps. Why? It's not much slower charging, and it will make your battery last a lot longer!

[/u]. Instead of 1.8amps, charge at 1.5amps. Why? It's not much slower charging, and it will make your battery last a lot longer![/quote] There is no evidence at all that charging at less than 1C is of any benefit to lipo longevity. No manufacturer specifies a lower rate. The only rechargeable that may benefit from this is SLOW charging, and forming charging NiCads/NiMh at 1/10C. Nicads? What are those? A lot of newer lipos actually spec 2C charging rate and higher end lipos are now 5C. You need a serious upgrade on charger and power supply to do that unless you bought a top end charger first time out. There are numerous steps you can take to increase lipo longevity, slow charging is not one. |

Stop! Don't listen to flydiver! He's in league with satan! Look, I'm trying to give you good, honest, half-baked nonsense, and he spoils it by giving out facts! Pah! Who would you trust, flydiver with his witchcraft and electrical sorcery, or me, with my good, wholesome, god-fearing, barely researched waffle? ( And be careful, your soul is riding on this!  |

OK, OK, I'm convinced. I'm charging at 1/2C, maybe even 1/4C from now on.
Obviously that sinister Cellpro 4S has been trying to deceive me with the temptation of charging at 3S!! EVIL! Dangerous!
NEVER AGAIN!
