Purchased three of these last winter. Hooked them up in parallel. They power my workshop which i only use on the weekends. I watch the discharge rate and never let them drop below 60%. I recharge them thru the week with a single 100 watt panel. They keep there charge very well and arent so huge and heavy that I have to build a room just for them :)
They came in handy shortly after i purchased them as we lost power. I threw them on a dolly with an inverter and ran my pellet stove for 2 hours. Seemed to be well within the acceptable discharge rate but i was new to the whole battery thing.
Looking forward to getting 3 more the next time i can sneak in a purchase for my solar hobby..
