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.
BVM primarily uses the "Matched Cell" technology
provided by ThunderPower of Las Vegas, Nevada.
ThunderPower tests and assembles the cells in the USA
and welds the power and balance wire connectors at the
length designated by BVM. Each battery’s voltage and
I.R.’s are double checked at BVM before shipping to you.
Use only a modern charger that has all of the
safety features available and the capability to fully
charge, accurate charge, and storage charge the 6600 and
7700 mAh batteries.
The batteries are shipped to you at a safe
storage charge of 3.85
.02 volts per cell. Begin by charging the batteries to
4.2 volts per cell on your charger, then bring them back
down to storage charge. This equals a "cycle". Cycle
them 3 times before the first flight. A properly
throttle managed flight with a BVM EJet and the EVF 10S,
12S or 16S will consume about 80% of the available power
in 6-7 minutes.
Limit the first few flights on a new set of
batteries to 5 minutes, thus using less than 70% of the
capacity. This gentle break-in procedure, and always
returning the batteries to storage charge soon after
use, will allow you to get hundreds of cycles and great
performance from your ThunderPower batteries.
DO NOT allow batteries to be
stored in a hot car.
If batteries are stored cold, warm
them to 55+ degrees F before flight.
ALWAYS check pack voltage when you install them
into the model for flight. The cells must be within .01
volts per cell to avoid damaging other batteries
connected in series.
#1: a 4S 2P pack fully charged = 16.80 volts
additional 4S 2P packs connected in series
should be 16.76-16.80 volts
Example #2: a 5S 2P pack
fully charged = 21 volts
additional 5S 2P packs connected in series
should be 20.95-21 volts
