Ep 4200's aka Firecrackers

[Colinevan]

After much debate on gp vs Ib cells, i needed to order some more cells, but with Gp not being available, iv chose the firecrackers.

Iv spoke to some racers and iv only heard good things about these cells. They have similar characteristucs as Ib cells but iv not heard any negative points on them as yet.

For £30 you get matched, zapped cells and above all assembled.

Anyone else running them?

If so what are your verdicts.
