In terms of battery, they are supposed to be more powerful than the original off I feel they take less. And support that can charge a battery and phone at the same time (but it was said for other buyers). Fortunately, there are two that's three with the original one so it can change when a battery is empty.
Conclusion of this purchase I would not say I advice and I am satisfied but I share. I think for the budget of this kit I should have put the money in and add a more powerful battery.
