Jason being your in Honk Kong the market there is VERY different there.Tamiya connectors and preassembled,unmatched are fine for most of your purchases.
Racers only account for 7-13% of the batter market anyway.
When it comes to racers this is what most are looking for.
Unassembled,no connector,and the following.
GP3300's are the way to go hands down.Cheaper for you as well as the consumer.Expecially in america where trinity owns the rights to Sanyo and Panasonic.
The yield higher voltage,true mah rating,and lower resistance than the Sanyo's.
The Sanyo's are fragile cells,not a true 3300mah all the time,less voltage and HIGHER resistance.Plus more expensive for the consumer.
Now I am speaking on prices based on american cells.
If people DIDNT know or new to this hobby GP's have been the best thing for electric since sliced bread.
Since the "EVIL" Trinity empire has distribution rights to Sanyo and Panasonic they control the pricing.Hell I paid more for my 1700 matched packs than I am for 3300's being GP's.
2400's are almost impossible to get ahold of over here due to being nicads.Plus anyone that follows batteries knows as soon as a NEWWER cell comes out trinity had sanyo weakin the cell that was BEFORE that.Like when 2400's were new they had SWEET voltage,long runtime and low resistance.As soon as the 3000's came out 2-3 months later you were down 20-30 seconds on runtime,voltage went from 1.16-1.17's at 20 amps to 1.14's and 1.15's.Resistance went from low to mid teens to low 20's.This has happened since 1700's.
So nicads or 2400's will probally be a bad choice.
Reasons are the following.Probally more expensive than GP3300's,less voltage,higher resistance and less runtime.
Goodluck with your buisness and I hope the following info helps.
*****Look me up on Ebay. I will have alot of stuff going up as 7/7/2016. User name is Dalracer.**** This is going to be a BIG ONE!!!!!!
Just wanted to say Thanks to RcTech for all these years of Great Information.
