Default Breaking in new battery

Hi all,
Just received my 2 packs of Apex Li Poly 2100mah batteries for my T rex. Just wondering how you guys break in new battery?
Thanks

Charge them at a rate less than or equal to their capacity on a lithium compatible charger. Then put them in your heli and fly.
LiPos do not have the same requirements that the older NiMH batteried did for cycling them at a low rate a few times to get the maximum capacity out of them

I have always been told that you run the LiPo 1/2 way down for the first 3 flights in order to get the max out of them.

I would assume he means that if the battery normaly lasts for 10 mins, run it for 5 mins then recharge it.

The 2 most important things to remember with LiPos.

1) Use a cell balancer regularly. A cell that is down on voltage compaired to the others will get over discharged during use and will not fully charge. Even worse, a cell that is higher than the others will overcharge and you do not want that with a LiPo pack. Smoke, fire, insurance claims...

2) Always start your model with a fully charged battery. Most ESCs have a low voltage cutout to prevent over discharging, BUT they measure the voltage when first turned on and use that figure to calculate what voltage to cut off at. If your battery is only half charged it will calculate a lower cut off and over discharge the battery...

When LIPO's come fresh from the factory, they are (usually) already 3/4 charged. For the best balance (and life) from the cells, it's better to use the battery in it's current, shipped state, rather than charging it first to top off the missing 1/4 and then using it.

After that initial discharge you can charge the battery normally. Like VinceHerman said. Use a 1C rate or less (equal to or less than the batteries rated capacity).

hi vince,
i was just wondering if you thought the optic 6 transmitter will work well with hummingbird elite 3d pro or not?
