Hi Roger
The 2 batteries in my photo are 33 amp hour,but there is plenty of room to go
to 38 or 44 amp hour,197mm x 166 x 171.

Hi Phil

My name is Peter. I received my KT No. 32 around Christmas time in Switzerland. After I finished my 25Pounder first, I am working now constantly but slowly on the KT. Because English is not my mother language I have to read the manuals many times and very carefully, not to make any mistakes. I follow your photos and descriptions with big interest, because they make me sure to mount the KT correct. Let me ask you one question depending the batteries: Somewhere outside the manuals is written that the KT needs 4 x 20 Ah-batteries? But as long as I can see in the KT-manuals and on your picture 2 powerful batteries should be enough! I have to check next, which suitable batteries are available in Switzerland. Your recommendation is important to me!

Many thanks for your answer.

Hi Peter
I hope you are enjoying your King Tiger building.
You are correct,the Motion Pack manual mentions 4 x 12 volt x 20 amp hour batteries
there are room for.
But the Electric Modules manual shows 2 x 12 volt 20 ah batteries connected in series
making 24v x 20 amp hour.
With 4 batteries they need to be connected in Series Parallel to make a set of 24 volt
x 40 amp hour,but this is not explained or shown in pictures.
The connections supplied with my kit are 2 x CP0198 battery links and 2 x CP0196
battery output leads.
These are not enough or correct to connect 4 batteries in series parallel which to
complicate matters there are at least 2 ways to connect them.
What is supplied though is suitable for 2 big 12 volt of more than 33 amp hour.
Connected up just like in the manual pictures.
I chose 2 big batteries rather than 4 smaller ones,for convenience of charging and
probably not much difference in the price.
Where it is possible to charge series connected batteries,parallel connected batteries
and Series parallel connected batteries,it has to be done in the correct way and not all
chargers are suitable.
If you want to use the 4 batteries check with Mark for a diagram,if you ask nice he may
even make you up some more leads,you need at least 2 more battery links but only one
of the output cables sets.
Here is a good link to a 10 page PDF file for printing called "Batteries and Chargers
connected in series Parallel.
Hope its of use to you and anyone else that is not sure on batteries.

If it doesn't take you there Google the same and you should still find it.

It works I just tried it

Hi Phil
Thank you very much for your fast explanations and the interesting link. I willl read everything carefully and try to understand. You will hear from me later.
Take care, Peter

I think 4 batteries was always an option with the bigger tanks. This is due to available space rather than necessity. 2 batteries is generally sufficient. If I use 4 batteries I would use them as 2 separate sets of 2 in series. This way if your batteries run out you switch to second back up set. Mark can supply additional battery cables.

[phil fitzpatrick]

Hi John
You could well be right because there was 2 sets of output leads.
It just needs the manual updating to keep up with the Tanks.
Cheers
Phil

[Peter Rosenwirth]

Thank you John and Phil

No I see more clear and I realize that space is not a big problem in the KT. I will look for batteries with the size you recommended Phil (2 x max 197mm x 166mm x 171mm).

I am enjoying my KT building, although its a challenge to me (I love to be challenged). I guess, the big thing is not to run the tank but to bring it running.
Thank you for assisting!
Peter

Hi Peter
The 2 batteries that are shown in my pictures that I am going to install are
12 volt 33 amp hour which are
length 195 mm
Width 130 mm
Height 164 mm
So when they on there side on the battery tray 130mm is plenty of room.
The Battery case size 197 x 166 x 171 is for the batteries above that size up to about
44 amp hour.
There is just enough clearance for the 166 mm but I will double check this for you
because my Battery tray is installed.
I think the 33 amp hour will be plenty big enough for me,but to give myself the option
of changing to a bigger size later I will double check the clearance for you.
Cheers
Phil

This should clarify the battery issue. This is from the FAQ in the Armortek Home page.
See the highlighted section re 4 batteries. I think the document that Phil posted should cover all the connections. I have always had plenty of running time on one set of batteries but carry a spare set just in case of running out of power.

What batteries do I need?

The Armortek range of models are designed to operate on a 24volt electrical system. You will need two 12volt batteries linked together in series. The tanks are supplied with a battery tray to suit two 20-24AmpHour gel type batteries. This will give about 80minutes running in normal mixed duty conditions WHEN USING THE ARMORTEK HIGH EFFICIENCY GEARBOX. You can of course fit larger batteries if you prefer, but you will need to make your own battery tray. Larger batteries give a longer running time, not more power. The SDKFZ7 half track is designed to use two 7Amp Hour batteries, giving two hours run time and the 222 uses two 5 amp hour batteries giving 90 minutes run time.

You also need the transmitter Ni-Cad packs that are supplied with your radio control equipment. THE RECIEVER IS POWERED FROM A BEC IN THE THE POWER SUPPLY MODULE

What size batteries do Armortek use: in the tanks?

Tanks

Length = 180
Height = 167
Width = 76

Half Track SDKFZ7

Length = 150
Height = 92
Width = 65

222

Length = 90
Height = 100
Width = 70

*How do I connect four batteries in my tank?

If you have TWO batteries, CONNECT THEM IN SERIES USING THE BATTERY LINK CABLE SUPPLIED IN THE MOTION PACK

If you have four batteries, you can choose to connect your batteries in one of two ways.
Option 1 Operate the batteries as two separate pairs. Each pair connected in series to give 24V and only one pair connected to the power supply module at any one time. This is just like having a main and a standby battery pack

Option 2 Operate the batteries as two pairs, each pair connected in series, and with the pairs connected in parallel, all connected to the power supply module. This gives you twice the battery storage capacity, but no standby.

*Where can I buy batteries?*There are many suppliers of suitable batteries however we recommend Hardwarexpress, they can be found on line at
http://www.hardwarexpress.co.uk/ if you order on line enter the code: HAZPACK01 which will automatically give you a 10% discount as an Armortek customer.

The following models all use two AGM20 OR 22 OR 24 batteries

•Tiger all models
•Panther ALL VARIANTS
•Jagdpanther
•Sherman
•King Tiger
•Centurion
•Comet
•Panzer III
•Panzer IV
•T34
The following models use two HGL7.5 batteries

•SDKFZ7
The following models use two HGL5 batteries

•SDKFZ222
•M2, M3 and M16 US half tracks

Thanks John
Very usefull info
Cheers
Phil

[Peter Rosenwirth]

Thank you both

I see quite clear now. Both solutions (seriell and parallel connections) have their advantages and disadvantages. Thank you for the really useful information.
Peter

[phil fitzpatrick]

Hi Peter
I have just double checked for you so that I don't give you wrong information,the
larger size battery 197 x 166 x 171 will deffinately fit on the battery tray as long
as the cap head screws that hold the turret ring gear onto the turret base are fitted
with the cap head undernieth or the excess thread is cut off,then you have about 10mm
clearance.
So you have plenty of choices over the battery size,larger ones or a pair of 20 amp hour
connected in series and another pair ready in reserve to be connected up.
Either way the Series method of connection as in the Armortek manual picture is the one
for you to use.
When I went to buy my 2 batteries they hadn't got the bigger case size so I bought the 33 amp hour,but at least I know that I can upgrade if I need to replace them.
Happy Tank Building
Cheers
Phil
