It's a concept that may be difficult to accept because we can not observe the chemical exchange taking place inside each cell.  But, it has been established in practice, that properly exercising LiPo cells during their initial use will contribute to the power output and increased cycle life.

Some Guidelines
For BVM "Matched Cell" Break-in
Featuring ThunderPower Pro Series Cells
10s system shown

   

Install the Saddle CellsTM in your model using adhesive backed Velcro to adhere them to the plywood battery support shelf.  For break-in purposes, they can rest on foam pads on the wings as shown.

Make sure that your transmitter (Spektrum 7) ATV adjustment's are set to 85% for high throttle and 75% for low throttle.

The goal is to run the freshly charged cells at 40-50 amps and consume about 70% of the available capacity, keeping the battery core temps around 100°F maximum.

To accomplish this without a good quality amp meter, position the throttle stick about 2/3rds position maximum and cycle it to low power a few times during a 2 minute run time.  Adjust this time on the following runs to accomplish the 70% target.

You can immediately recharge the batteries @ 1C if the temps are below 125°F.  Always use a cell balancer.

Cycle the packs 4-5 times on the ground at the shop.  Then, fly the model conservatively for the first few flights with the goal of utilizing about 70% of the mAh capacity.

On subsequent flights, the goal should be to utilize 80% or less of the pack capacity with post flight pack temps below 125°F.  Give yourself time to develop a flight routine (profile) that maximizes the performance and flight time without over taxing the batteries.  Following this break-in course will go a long way towards maximizing the cycle life of your LiPo power packs.

Aerodynamically clean models like the BVM Electra, Sabre, and F-80 with EVF power allow some power-off cruising time following high speed passes and zoom climbs that add greatly to total flight time. 

Note:  Exceeding the 80% capacity and 125°F guidelines won't necessarily ruin the batteries but experience has shown that the cycle life may be reduced.
