I like my wires to be super neat and these lipo's make that easier. I used to run the Track Power 3200's and had to make my own battery posts and use rubber strips to stop the packs moving. With these its just a case of a 3mm spacer under the standard posts and thats it. Like Piman says, its the locators on the bottom of the packs that make the difference. No more rubbed belts. Its alot of cash, I bought two sets of 4800 40c saddles and two 5300 40c LRP Sticks which was near enough £400, BUT thats all my cars powered reliably for two seasons at least.
I wouldn't bother with a Pulsar 3 tho, I use two Propeak Sigma EQ's. Its 12/240v, 6amp max charge, They ballance charge, do all the batterys out at the mo plus the new LiFe type, add to that I only paid £65 for one new. Much better vaue than the 12v only, none ballancing £150 Pulsar 3
