SO after spending hours putting my Matrix back together this week I finally got to bring it to the track. Everything was READY! EXCEPT I think the battery is dying in my ofna starter box. It doesnt seem to want to take or hold a charge. Its fairly new but who knows? Where can I get a new battery for it? There are NO hobby shops local so I am hoping that it may be a readily available item.... ANY ADVICE?!?!?!!! THANKS!

Try find a DIY shop. Search for a 12V battery. I just bought a brand new battery of 17 Ah and it rocks It start's my Vspec without hesitation at all.

OsirisF16,
Thanks for the advice. I am a bit confused. When you say do a search where do you mean? Google search or somewhere else? I am not that good with Electrics so maybe you can tell me what 17 ah does? Is that the size I should get?

Your motor in your starter box needs 12 volts, so that is standard. Ah (Amper per hour) is the capacity of the battery, or just in simple words, is the capacity of how many times you can use the starer box. Simply, a 17 Ah is better than a 12 Ah, and a 50 Ah is better than the 17 Ah. The problem of course is the mass the battery is taking. A battery of 50 Ah is very bigger than that of 17 Ah. In conclusion, you must buy a battery of 12 Vlots (standard) and see what size you prefer. There are chargers in the market so you can charge the Lithioum batteries, don't worry, you don't gonna throw the battery to the rubbish once it finishes.
