Help Charging LiFePo4 Battery

[Shuntfield]

Hi All

I have this battery



its for my Futaba 4GRS transmitter.

I have a Dynamite Passport 100w charger, that will charge LiFePo4 (LiFe) batteries.

It asks what the charge rate and end cell voltage should be, but I am not sure what they should be.

The hobbyking website says:

Capacity(mAh) 2100
Config (s) 2
Discharge (c) 20
Weight (g) 103
Max Charge Rate (C) 5

So charge rate I guess is 2.1A x 5 so around 10A but I'm happy to charge at a lower rate say 5A.

However what should the end cell voltage be?

Sorry if I sound dull, its a bit new to me and this is the only LiFe battery I have!

Cheers

Graham
