Bests & Worsts Reviews from Amazon

I bought 10 of these for a 1600 watt system. All renogy components. It takes about two weeks to charge them up from the panels. After countless hours of troubleshooting renogy claims this is normal. Apparently charging the voltage up to 60% then switching to float mode is normal... I don't know how you can advertise a hundred amp hours on a battery when your very own charge controllers only provide about 20 usable amp hours. I had much greater expectations for this company. These batteries just like the solar panels they sell have no way to confirm their efficiency because adequate data is not provided. Should Renogy address these issues properly I will update my review. Update: Still no data to benchmark this product....12/19/17
