Hi,
At the moment I’m using Sealed Acid batteries, two 9AH. Those are not brand new, and very heavy.
Are three options for new batteries:
- Ballistic Battery 12 Cell EVO 2

http://www.ebay.com/itm/360584178221 - (x3 paralel) Turnigy 5000 mAh 4S 1P 14.8v

First option, seems like very expensive, but really good cells.
Second option, in the middle.
Third option, are three packs connected together in parallel, and price are up to £100. and are possibility to use separately for smaller and lighter setup.
What you will choose? And why?
