RE: parents say no to lipo...
any batt. should be considered dangerous-doesnt matter what type ofbatt. u have-the result will be the same if you overcharge or missuse it-just charge it within spec and u shouldnt have any problems. i myself have fallen victim to the tenergy batts-bought 4 of um-im down to 1 and it doesnt hold a good charge-and i always charge them right w/ peak chargers-other 3 melted the case's when i had a older e-maxx. i learned my lesson-dont by batts from allbattery on ebay-lol
