I don't understand all the stuff about a HEAVIER LIPO
If it's too light - get some strips of Automotive Tire Lead Weights used for balancing Aluminum wheels.
It has sticky tape already applied, peel it and stick it right on your 3200 LIPO Pack. (Or better yet, to the chassis under where the battery goes to get the weight as low as possible...and you won't need to put weight on EACH pack you may have.)
I'm hoping instead of having to make batteries heavier, instead make rules LIGHTER
I've seen ROAR raise weight rules because "Batteries are heavier now", so now that there are LIGHT batteries - will they do the same thing to accomodate this situation?
