Frequently Asked Questions
Clear answers to common questions about this product, setup, compatibility, and use.
Where can the 2.4-inch REGO battery fit that a conventional case cannot?
Its slim case can mount behind seats, under some floors, or against a canopy using the supplied bracket system. Measure the 22.8 by 11.4 inch face, cable clearance, required service space, and structural attachment before assuming every narrow cavity is suitable.
Does Renogy's solid-state label mean the REGO battery has no liquid electrolyte?
No. Renogy states that this semi-solid-state design still contains about 10 percent liquid electrolyte by weight. Judge it by the published safety construction, BMS, enclosure, current ratings, heating, and certifications rather than assuming an all-solid cell.
Can one 104Ah REGO battery really supply a 2000W inverter?
Renogy markets one battery for a 2000W inverter and publishes a 200A continuous output. Confirm the inverter's maximum DC draw and surge, keep other loads in the calculation, and use cables, fuse, disconnect, and terminals designed for the resulting high current.
When does the REGO self-heater turn on and off during cold charging?
Renogy lists heating beginning around 40F and ending around 50F when suitable charging power is present. The 150W heater uses incoming energy, so the source must have enough capacity and charging will be delayed while the cells warm.
Is the vibration-resistant mounting bracket included with the self-heating REGO battery?
Yes. Renogy lists the battery, bracket kit, two long terminal bolts, two standard terminal bolts, two insulating sleeves, and manual. High-current cable, fuse, disconnect, charger, busbars, and compatible CAN equipment remain separate.
