I keep hearing everybody tell me that the LiPos hold their voltage under a higher load.. but I'm just not seeing it as a problem for NiMh. At our track we have a lot of folks with LiPo batteries.. all brands.. Orion, Trinity, TrakPower and others.. The consensus is that the NiMh have more punch in stock & mod... maybe we just have lots of really well matched packs... The weight of the LiPos might make you feel like they are giving you more power.. but its just the weight factor allowing you to get to speed faster.. I can definitely tell the difference practicing with my Orion 3200 in my stock buggy.. It flies farther over jumps and feels much lighter.

The runtime however is the biggest deal.. my 3200 LiPo has the runtime of a 4200 NiMh and my 4800 LiPo runs forever! lol...

If I get the lifetime out of these LiPo that I hear about.. then it's been a good deal! Other than that, I love'em!

Not to sure about these Lithium Ion (A123)packs.. they don't fit right and have a lower voltage than LiPo or NiMh.. Might be ok for bashing.. but not racing.

Have fun! Good Luck!
