Starter Box Battery
Hi
I've recently taken the advise in this forum to use a 12V car battery to start my Hyper 7 Pro during the running phase where the engine's really tight. Now that the engine's run in. I'm unsure whether to buy two 7.2V pattery back to fit in the starter box, or a 12V small lead acid battery to put in the starter box or carry on with the 12V car battery which has got plenty of current. Any advise and recommendation on which 7.2V packs to consider, there seem to be hundreds to choose from.
Cheers

RE: Starter Box Battery
Hi Gary
try www.ardelectronics.com do a product search for 130-00191
it is a FIAMM-GS LEAD ACID BATTERY 12V 7.2AH. it is a sealed battery that fits most starter boxes that use 2 * 7.2v stick packs.
you can also order a charger from the same company

Do not do 2 7.2 volt bats... You will regret it... Go for the 12v it makes every bit of difference.
How far is Oxford from Knaresborough? You have any good tracks there?

The 12v batts that fit into most boxes are just Motorcycle or Security Alarm batts... I get the from a local batt dealer... made by Interstate Battery...

RE: Starter Box Battery
The 12 volt is a great way to go and of course the other option is the 14.4 volt with the battery packs.
The 12 volt in my opinion is the easiest of the two, while it does add weight to your field setup it does not require a high dollar charger to charge it. Gel cells can be charged with a basic cheapo wall charger. Keep in mind that with the Gel cell that you want to maintain a voltage above 12 volts at all times. Once the voltage drops below that the cell begins to deteriorate. There are chargers available that will monitor your gel cell and keep it at a certain charged voltage. Basically when its not in use you just leave it on the charger and its always ready to go. I think those type chargers run around $40 or so. Without that kind of charger you need to monitor the voltage of the battery and charge it when it begins to get low.
The battery packs require a little more of a charger and depending on what cells you get, may need to be cycled from time to time. The benefit is that they are lighter and you have the additional 2.4 volts of push on the starter wheel. 2.4 volts does not sound like much, but when you have a hard to start engine 2.4 volts can make a difference.
I have a gel cell in my field box and I just wire my starter box up to my power panel. I do keep a couple of 7.2 Nicad sport packs around for a little more push. Although I never use them they are there if I need them.

RE: Starter Box Battery
Thanks everyone. I think I'm going to plump for a 12V sealed lead acid battery recommended by MisterLister.
I've checked where Knaresborough is Studysession in relation to Oxford, your probably about 150 miles away. I haven't sussed out the tracks around this way yet. Now that I've run in the engine, I'll be starting to have a look around.
Cheers
