From most reviewers almost everything has already been said, so just briefly to confirm that the performance of these batteries is truly enormous - my LED Camping Lamp our cellar lights as bright as never made; Lack technical device I have no objective value to amperes or the like. do.
Emphasized again is the relatively high weight of these batteries, which accounts for the performance well, but should be considered for portable solutions. As for me, in stationary use no problem therefore full purchase recommendation!
