R/C packs for hi-power mods?

[Phaserburn]

This is a "just wondering" post. Why hasn't someone harnessed the already conveniently available R/C nimh packs for a hi-power led or incan mod platform? They are already set up for quick charging outside or perhaps inside a light's body with uniform clip attachments. It seems like it would be handy. Maybe 2 in parallel for serious power apps?

For me, there are several reasons.

1. In retail packs (such as from RadioShack) the mystery cells they use and predominantly nicad chemistry make for large packs for a given voltage and capacity. Also, these typically come in double stack flat style which can't be used in a tube torch.

2. The premium packs built by vendors such as www.cheapbatterypacks.com and www.battlepacks.com are a bit pricy but you know they use good cells.

3. I prefer to roll my own to tailor the packs for specific voltage and capacity needs.

4. The connectors are either a plus or a minus depending on how involved you want to get.

NiCd packs, in high performance R/C racing are dead. Both of the major racing organizations (ROAR and IFMAR) sanction the use of NiMH cells.

Sanyo and Panasonic are the most popular. Smaller comnpanies will purchase cells, and then cycle them (sometimes called a "pushed" cell)to get slightly increased performance.

In an application where you don't have a 9-turn electric motor drawing 30+ amps, these cells are overkill in a lighting application.

In my semi-pro racing days, the super cell was a Sanyo 1700SCR Nicad. Today, the current supercell is a Panasonic 3300MAH NiMH. How times have changed!
