Charging Lipos

Charging Lipos
I just bought 2 SMC 6000mah 28c lipos... I have been told when charging lipos you charge the amperage equal to the level of capacity. ie. 5000mah charge at 5 amps, 4000mah charge at 4amps ect.
Is this true? Can I charge my 6000mah at 6 amps? actually my charger only goes up to 5 amps. What is the rule of thumb on this?

That is correct. Charging at 1C is safest for Lipos. Of course lower charge rate is not going to harm then either. If you can only go up to 5 Amps on your charger then thats ok, it will just take a little longer to charge.

What do you mean when you say 1C ?

B. A. you got pm!

SMC will tell you, you can charge @ 2c.

2C meaning he can charge them at 12amps?.. I mean, If his charger was able to support it?
I charge my SMC 25C 4900 Saddle Pack 2S packs at 4.9amps and my 4800 reedy 20C saddle packs at 4.8amps
Takes about an hour for each and I balance charge them every 10 charges or so just to make sure everything is kosher.
The most important thing is to make sure you are using a Lipo Charger!!!!!

wow lets make a Bomb by charging at more than 1c..
This is the SMC 7.4V Sport Max 6000mAh 28C LiPo Battery.
FEATURES: Hard case Traxxas plug Balance port
INCLUDES: One 7.4V Sport Max 6000mAh 28C LiPo Battery with Traxxas connector
REQUIRES: LiPo compatible charger and balancer
SPECS: Length: 39mm (1.5") Width: 45mm (1.8") Height: 24mm (0.94") Capacity: 6000mAh Number of Cells: 2 Rated Voltage: 7.4V
COMMENTS: READ the ENTIRE instruction sheet included with battery before use ALWAYS use a LiPo-approved Charger ALWAYS use a LiPo Cell Balancer NEVER Charge over 4.2V per cell NEVER Charge at currents greater than 1C NEVER Charge through the "To ESC or "DISCHARGE" lead NEVER Trickle Charge NEVER allow to Discharge below 2.5V per cell NEVER disassemble or modify pack wiring in any way or puncture cells NEVER place on combustible materials or leave unattended during charging ALWAYS Charge in a fireproof location ALWAYS set charger's output volts to match battery volts ALWAYS keep out of reach of children
STRAIGHT FROM SMC.. sorry but that is shear stupidity to charge a lipo at more than 1c sooner or later it will fail and it wont be nice..Gee wondering why all these lipo chargers only go to 6 or less amp charge rates.. NOT..

The newer Hyperion chargers can charge at 20amps.
It all depends on what the lipo manufacturer tells you for his lipos. If they say 1C, you's best be charging at 1C or below. If they say 2C, you can charge at up to 2C. It saves a little time.
Lipo tech is charging pretty rapidly and the newer lipos coming out have a better, diff medium inside and can support charging at higher rates. The newer lipos are often capable of 2C (or higher) charge rates.
Bottom line - follow what manufacturer recommends for charge rates.
