After buying 4 of these so far, they are all absolutely spot on regarding voltages and battery life, they seem to be using good cells as there almost zero variance across the 4 batts... maybe they arent the best value for money when it comes to £ per watt, but for the size and versatility in wiring options, and their light weight means they are able to be used in a myriad of applications, fyi they are about 1kg each, and have a continuous output of 8amp, with a burst of upto 30a for 10 seconds, it comes well packaged with foam padding, and you get 2 wires with the f connectors either end in the box... Review: So much better than Lead Acid - I bought one of these to use with my Yaesu FT-891 Radio for portable use. I was sceptical at first. Performed a load of testing (I do this every time I buy new batteries) to push this battery to the limit. It performed flawlessly, in fact it out performs the specs. Really happy with the results and so much lighter to carry around in a rucksack. So happy I bought a second one. Just by these and leave the Lead Acid ones at home. ## Features - Wide Application:LiFePo4 lithium battery is the most stable battery and it is compatible for RV, caravan, marine, camper, alarm systems,solar panel or used as backup power supply etc - Long Service Life:Lithium rechargeable battery cycles more than 4000 times，which is more than 8 times comparing with Lead-acid batteries(usually only last for 300-400 cycles).And the battery provides 100% of rated capacity each time when you use it - 1/3 Lightweight: The 8Ah lithium battery weights only 2.31 pounds(1.05kg), which is only 1/3 of the weight of a lead-acid battery.
