No one said top of the line... Just stated : not Junk!

As for me their 4S Hardcase Batteries are sufficient enough for my 1:8 Onroad, 1:8 Truggy and my 1:8 Buggies. I run their 2S shorties in F1, and their Regular Long 2S Packs in USGT & USGT Fwd. I also have Zeee packs powering my Starterboxes. They have all performed just fine, charged at recommended amperage's ( Read - Never Overcharged) and always Balanced and Stored correctly.

If you take the time to Maintain you Pack's, a "Top of the Line" pack is not a need!!! Yes they may develop a crack in the hard case here and there, but so do other brands as well.

Been there and done that with Trinity,Team Orion, SMC and LRP! Now I run Zeee just fine, they work for me, and my wallet.

So as to the OP's inquiry, that would be my feedback.
