No matter what LiPo battery pack you use, do NOT charge it in the car or in your house. They can and will catch fire to a level that almost looks like an explosion. The resultant fire will destroy whatever it is in or near.

Use a short extension cord from your cigarette lighter in the car to get it away from the car for charging, and if charging it at home, do it outside, well away from your house.

There have been several recorded instances of homes burned down and cars/vans/trucks completely gutted as a result of fires caused by problems with LiPo packs, even small ones!!

Be very careful. These things really require special care and feeding.

Don't get me wrong, they are great for what they do, but, as said, they do require special caution when charging.
