Vapextech Receiver RX AA Pack
2500mAh 6v Nimh Instants - Flat Configuration - Futaba Connector
Why not treat your model to a
brand new INSTANT battery pack.
Instant rechargeable packs are
manufactured from cells that have a much lower self discharge rate than normal
Nimh cells. Because of this you will find that these battery packs when left
for a while will not need as much charging that a conventional pack would.
If you want to recharge your
batteries after some use you only charge what you have used. You
don't waste extra time and cost charging batteries that have just let
their power drain away.
Instant packs do have some power in
them when new however it is STRONGLY RECOMMENDED that all RC battery packs are
charged fully and tested prior to use in RC Models.
Please Note - The battery pack you
receive will not have the printed label as shown in the photo. I can assure you
though that the packs are constructed from genuine Vapextech Instant Cells.

Charging Advice
I have been using both the Vapextech
standard Nimh packs and the low self discharge Instants in my own model
aircraft and transmitter for many years and they have served me well during
that time.
My own preferred method of charging is to use a Voltage Peak Detect charger
which can both fast charge the pack and then automatically cut off when the
pack is fully charged. I tend to charge the 9.6v, 6v and 4.8v AA size packs at
700mA and the 6v and 4.8v AAA packs at 400mA. I find these rates to be a good
balance between fast charging while also not putting the cells under too much
stress. The result of this has been that my battery packs have a good long
lifespan and I've never had any failures at all.
Alternatively you can use a plug in the wall trickle charger however the charge
rate should not be greater than 75mA. If a charge rate higher than this is used
there is the possibility of the battery continuing to be charged up even when
it is in a fully charged state. The battery cannot then vent off the same
energy being put into it and the cells will get hot which can then cause them
to be damaged.
This is why I personally always use a Voltage Peak detect charger and it also has
the added benefit of displaying the amount of charge that has been put into a
battery pack, plus they generally also have a cycle function that discharges
the pack to a safe level and then puts a full charge into it again.
About me
As I've already said I have been
flying RC model aircraft and gliders for over 36 years and this little Ebay
business is a good way to subsidise my hobby and especially my unhealthy
addiction to fast gliders. Being a modeller I also know the sort of service
that you expect so I will always send out any orders practically as soon as I
receive them (there's a Post Box just 20m away) and if you ever have a problem
or need a little advice I'm always happy to help as best I can.
I hope you've found that information
helpful and I look forward to supplying my batteries to you.
