Lipo Experiences

[markwilliamson2001]

Hey guys..

I ran first time with Lipo on Friday, and it was interesting to say the least.
Good points:

Charged up packs (2) on wednesday evening from packet. Took about 25 minutes till they reached 8.40 volts and then pulled them off. Fitted to car, ran without problems, then after 1 race, topped up on charger with balancer.

No assembling, no battery bars or connectors to solder up.
I used the Trakpower 3200 pack which easily lasted 1 race (could maybe have done 2 races on 1 pack). Indoors with a 7.5L, the car was a handful (too much power, would have been okay in a 4wd I expect). Motor, battery and speedo came off cool after race, so all good! Could have got away with a 13.5 brushless I reckon on the tight indoor track with the Lipo Pack. biggest difference noticed was the lack of weight which affected jumping, and high speed balance of the car. I had to add 40g of weight to the front of the car around the servo to balance it up. The car definatly felt more stable with my older GP3300 NIMH's in, but I will try and add more weight to the car to make it more stable soon (fit a slim lead sheet under the lipo pack) and bring it closer to the weight of NIMH cells. I hope in my 4wd car the difference will not be as noticable.

Bad points (my fault really):
I was using 3rd party corally connectors which were a looser fit in the battery than I would have liked. If I rolled the car they came out very easily. I tried an older 'proper' corally on an old piece of wire and it was much more secure. Had to tape in connectors which was a bit unsightly, but worked. Just to change speedo to battery connectors now.

Roll on Lipo!
