- No, the largest market is handheld tools. Powered tools needs high currents, but
- not high as rc-models.

- I've seen some adverts about russian rechargable lithium-cells with very high
- capacity compared with both Ni-Hy or Ni-Cd cells. It seems a lithium cell of
- same voltage and weight has 10 Ah compared with 1.5-2A for Ni-Cd and maybe
- 3Ah for Ni-Hy.
