Review: Reliable storage of sun power! - My first lithium battery, purchased for a project to play with solar power for lights in an outbuilding. The battery has a very decent output and was upt to the job with no issues. Charging has presented no problems, hooked up to a couple of PV panels and a charge controller. There seems to be enough oomph from this that I added a 12v to 5v buck converter and am also powering a CCTV network camera. Hasn't let me down at all so fully recommend this battery to anyone with electric storage needs like ours. Nice bit of kit!
Review: Great lightweight battery - Excellant product. Used for our electric outboard and it last the day no problem. Small size and very light compared to conventional batteries
