7.1 kg per battery, that's close to 80 pounds of SLAs you have in there. Ping 60V30Ah is 40 pounds. Half the weight and more than three times the power and will last up to 4 times longer than those SLAs. Those SLAs will only have 80% capacity after 400 cycles and dropping fast after that so you have only one year at max to get those lithiums. But no pressure from me
Hope you don't get to much cold weather where you are 'cause those graphs on how the cold affects the capacity are pathetic.
But no pressure
And man! Do they have a C rating? It looks like they have a ton of voltage sag just with a 3 watt light bulb. But no pressure there, take your time
