they are not understaood

i have 4 trakpower, and loan em out at the sheffield biws, i run one pack myself, and have had no problem. i took a front corner completly off my xray while flat out on the straight, lipo was fine

chargers can be had for £30 ish

clubs are covered by the brca to use em (insurance)
the best way is to only allow packs in manufactures casing

some of us (trakpower drivers) were asked to abuse our lipos while testing

this ranged from charging at 10 amp (lipo only charger) and hard hits/jumps.
no problems at all

three main rules with lipo
only use lipo charger
dont discharge below 6 volt, some speedo's have this feature, device can be bought from novak/trakpower
let em cool if warm before charging

DCM i would hardly class nimh as safe! a young lady on rcracechat has poss lost one eye and had reduced vision in the other, from nimh exploding.
the current 4200 are poping like WWII bombs!
