Probably. LifePo4 bats are vastly superior to lithium ion bats and they are a good bit more expensive, hence the price difference. Google up some battery fires and see.So the one ttown suggested is safer than the Allwei one?
Lithium ion beats the LifePo4 in size, weight and price only. LifePo4 is just too big and heavy to be used in cars, and if they could use them, electric cars would be a more popular than they are.
