Li Poly breakin procedure

       Remove this ad - become a site supporter!
A short interesting guidline I found on net for proper breakin and maintenence when running Li-Poly batts.

Battery Break-in Procedure:

Contrary to popular beliefs that lithium polymer battery packs need no "break-in" period, before you run new Li-Poly packs continuously at their maximum discharge rate, we recommend you cycle the battery packs at no more than 7C for a minimum of 15 cycles down to 3.0V per cell or until the PROPERLY SET Low Voltage Cut-Off (LVC) on your ESC kicks in. All Li-Poly packs are to be charged at a maximum 1C.

By following this break-in procedure, your batteries will run much cooler when you run them continuously at the maximum discharge rates.

How do I calculate 7C?

If your battery pack capacity is say 1050 mAh with a charge rate of 1.05 A, 7C is simply 7 x Charge Rate or:

7 x 1.05 A = 7.35 A

In this case with the 1050 mAh pack, you should discharge no more than 7.35 A.

This is the safety instruction sheet that come with my Li-po, it gives a pretty good break down of what to do and what not to do. I just thought I would post it for anyone that cares.
