Actually I can't afford to buy kits, ESC or batts in my country so I order from US ou Japan most of the time which is quite bad for our LHS (where I just buy small stuff like pinion gears ($7), or motor cleaner) Taxes are so high here!

SANYO to Electrify Its Nickel Metal Hydride Batteries
With New Electrode Material 'Superlattice Alloy'
Tokyo, November. 27, 2003---SANYO Electric Co., Ltd. the world's leading producer of rechargeable batteries announce the successful development of a new electrode material, 'Superlattice Alloy' for Nickel Metal Hydride batteries. 'Superlattice Alloy' has a different make up than conventional material this distinctive structure helps it to achieve its high performance. SANYO will continue to move forward in the development of Nickel Metal Hydride batteries using this new electrode material with higher capacity and higher performance than conventional material.

In 1990 SANYO Electric Co., Ltd. succeeded in having the world's first Nickel Metal Hydride batteries for utilization. Since that time, SANYO has continued to make improvements to be an industry leader and hold the world's top share in numbers of batteries shipped. (According to 2002 Fuji Economic Research)

Will start using batteries with 'Superlattice Alloy' material for mobile phones which need to work in low temperatures and are under strong price constraints. Also plan to utilize the high capacity, temperature and discharge features of 'Superlattice Alloy' for electric power tools and HEVs (Hybrid Electric Vehicles).

The development of the negative electrode material 'Nickel Hydrogen-Absorbing Alloy' contributed to the high performance of the Nickel Metal Hydride battery. 'Nickel Hydrogen-Absorbing Alloy' was superior from the point of utilization so the basic structure was maintained while continuing with improvements. However, this time SANYO has succeeded in the utilization of a new negative electrode material, 'Superlattice Alloy' that has a completely different structure and realized high performance for Nickel Metal Hydride batteries. Expect Nickel Metal Hydride batteries to evolve further in the future.
Main features
1. High capacity that exceeds conventional Nickel Metal Hydride batteries
2. Ideal for high power use with excellent discharge property and improved low temperature characteristic
3. Low cost possibilities
4. Positive results attained from technology cooperation with the Toshiba group


(1) High capacity that exceeds conventional Nickel Metal Hydride batteries

Possible with 'Superlattice Alloy' to increase capacity approximately 25% compared to conventional negative electrode material.


(2) Ideal for high power use with excellent discharge property and improved low temperature characteristic

'Superlattice Alloy' has a superior discharge performance than conventional negative electrode material*1, making it ideal for mobile phones that are used in low temperatures and for electric power tools and HEVs (Hybrid Electric Vehicles) that require a high rate of discharge.


(3) Low cost possibilities

Conventional negative electrode material*1 when charged and discharged repeatedly would break into tiny particles from the expansion and contraction. To prevent this phenomenon of tiny particles breaking up, the material cobalt was essential. Cobalt is a precious resource that raised costs for Nickel Metal Hydride batteries. 'Superlattice Alloy' experiences less particle break up so it's possible to decrease the amount of cobalt or use no cobalt at all, resulting in an increase in cost competitiveness.

*1 Conventional negative electrode material: AB5 model called 'Nickel Hydrogen-Absorbing Alloy'


(4) Positive results attained from technology cooperation with the Toshiba group

Toshiba Corporation and Toshiba Battery Co., Ltd. announced in 2000 the developed of 'Superlattice Alloy' for Nickel Metal Hydride battery use, but didn't reach the deployment stage. After Toshiba Battery Co., Ltd. transferred its Nickel Metal Hydride battery business to SANYO in April 2001, SANYO continued the research for utilization of 'Superlattice Alloy'. SANYO succeeded in improving the life cycle of the battery making it ready for utilization. This achievement is the result of SANYO Electric Co., Ltd. and the Toshiba group's collaborative technology efforts.

I will just have to see how they are on the track
The cases of the shorter GP3300's that I've received have been very similar in numbers to the previous ones. It appears the primary way they made them shorter was by not having the postive tab extend past the outer edge of the cell at all.

i bet they will still be more expensive than 3300 cells even tho they say tehy will be cheaper.

Default Depends on the Trinity factor

If Trinity keeps Sanyo R/C exclusive, they will be very costly. GP3300's are not a Trinity exclusive.

thanks

eddie is right on the 12 year time line being off

i got Sanyo 1700 SCEs back in early 1988 using a Medical Supply Company. at that time they were not available thru or to RC companies.

i ran at a ROAR 12th race at SRS in AZ in March 1989 and they weren't ROAR legal. so i had to use 1200SC's. they were teching hard....checking weight, diameter, & markings. at that time SCRs were 1300's but were not good for 12th and the 1400SCR (i think) came out in 1990

shortly there after i got stationed in OK, Japan and in 1990 i was looking thru a Japanese RC mag and saw the prototype 2000+nimh Sanyo sub c's. too bad we had to go thru nicads 1700SCRC, 2000, 2400 for 9 more years
