So it's time for a new pack and pretty sure I'm ready to order next week. So if I can choose from 25R, 30Q or VTC6 which way would I want to go. I read and read and always end up confused. When I compare the cells it doesn't really end up a fair comparison since I'll buy the cells to get the amps I want. Meaning if I go 25R I'll probably go 20s15p for a 37.5 amp pack. If I go 30Q then it will be 20213p for a 39 amp pack and lastly VTC6 will be a 20s12p for a 37.44 pack. As far as current draw I'm running a QS205 and MaxE combo dumping 14kw in which ends up being about 200 amps peak. The 25R pack can hit 300 amps continuous, the 30Q can do 195 and the VTC6 leads the pack with a 360 amp continuous rating. I have read the 30Q has no problem dumping more but gets hot with continuous high levels.
So on a per cell rating the VTC6 wins hands down in all ways but what I can't figure out is if all the packs are close in actual amp capacity then would the cells be closer to one another in finished pack form? 25R has always performed well, 30Q has many followers and the VTC6 was supposed to be king of the hill.
Pricing is similar on the higher capacity cells figuring in total capacity with the 20s13p 30Q being $874, the 20s12p VTC6 being $895 and the best cost per amp rating going to the 20s15p 25R at $733! I like the idea of the lighter pack with the VTC6 being about 6 lbs lighter than the 25R pack by loosing 60 cells. At the end of the day I'm looking at longevity, lack of voltage drift and mucho power so any opinions are welcome to this thread.
Appreciate any advice given.
Thanks,
Tom
