Just a little teaser for you:
Perfect fit. The nicely curved upward edges of the battery plate hold the cells in perfectly, and length wise its a near perfect fit for the existing straps, though I may see about some more heavy-duty items if need be. I also finished the 2nd pack tonight, and re-jigged the 1st pack to tidy it up- hopefully the shrink wrap will come tomorrow so I can get them wrapped up and completely finished, ready for some high speed action when the weather dries up. Think I might put some bullet connectors on my Hvmaxx I so can swap it between the existing system and the MMM esc- 6s2p A123 should be interesting on a 3100kv motor.....
