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
