Rubix Giga Stack Series RGS51205 10.5kWh 205Ah 48V LiFePO4...

ok so my husband set this up with our solar panels after last year's ice storm knocked out our power for 6 days. we were NOT going through that again lol. its been running perfect since april. we run the fridge, some lights, and the TV off it at night no problem. honestly dont even notice the difference from grid power. customer service was really helpful when we had a question about the wiring. 5 stars no question

Rubix R-Series Base & Lid

my battery lives in a pretty cramped mechanical room alongside the water heater and pressure tank. space is tight and I was worried about anything bumping into the terminals. the lid completely solves that. fits snug, doesnt pop off if something nudges it, and the base means the whole unit sits flat and level even though my floor definitely isnt. for a small accessory it made a real difference in how comfortable I feel about the install. happy with it

Rubix Stack Series RS51100 5.12kWh 100Ah 48V LiFePO4 Battery

converted a sprinter van and spent a long time going back and forth on which battery to go with. ended up here and zero regrets. runs my fridge 24/7, a diesel heater controller, lighting, laptop, and a small inverter for the occasional power tool. been fulltime in the van since June and drove through the desert in July — temps inside the van were brutal but the battery was totally fine. charges fast with my 600W roof array. fits perfectly in the cabinet I built too, dimensions are exactly as listed which sounds obvious but some brands are off. love this thing

Rubix Stack Series Base & Lid

got this with my second battery and man it makes the whole thing look so much more professional. the base grips the floor real good, no wobble at all. lid snaps on tight. nothing complicated just does exactly what its supposed to do. if you got more than one of these batteries just buy the base and lid you wont regret it

do i actually need this base and lid or can i just stack the batteries without it

A1 SolarStore

Totally fair question — the batteries CAN technically stack without the base and lid, that's part of what makes the Rubix system so flexible. But we really do recommend picking it up. The base and lid make your installation look neat and clean and also bring the batteries up off the floor, which is great for airflow and just looks way more professional. If you're putting this in a utility room or garage that people will see, you'll be glad you got it.
