Default RE: quick question about lipos

<div>Short answer, NO.</div><div>
</div><div>
</div><div>
</div><div>Long answer. . .</div><div>
</div>LifePo packs are allot more durable and robust.  They can take a beating and be rapid charged.<div>
</div><div>LiPo's can easily be over heated and blow up if not charged properly.  They also can not be run down below 3.0 V per cell (most people stop running when they hit 3.3v/cell) or they suffer damage and will loose charge capacity dramatically.</div><div>
</div><div>Lipo's have more a better power to weight ratio, but only last about 1000 cycles and take about 1 hour to charge.  LifePo's have slightly higher power to weight ratio, but last allot longer and can be charged (with the appropriate charger) in about 15 minutes. (pack size dependent)</div><div>
</div><div>here are some quick stats from the powerfull wikipedia;</div><div>
