Product Description

This 2-pack of Renogy PRO 12V 200Ah smart lithium iron phosphate batteries builds a 400Ah, 5.12kWh 12V bank with Bluetooth monitoring, self-heating, and IP67-rated housings. Wired in parallel, the pair supports up to 400A of combined continuous discharge — enough headroom for a large 12V inverter and a full day of real loads.

Who This Is For

Two of these batteries are the working heart of a serious campervan, 5th wheel, boat, or off-grid shed: 5.12kWh runs refrigeration, lighting, electronics, and an inverter without constant charge anxiety. It is the right starting point if you plan to run a 3,000W-class 12V inverter — the Renogy REGO 3000W 12V split-phase inverter charger draws roughly 250A at full load, which a single 200Ah battery cannot sustain but this pair handles with margin.

Key Features

  • Two 200Ah, 12.8V LiFePO4 batteries — 400Ah and 5.12kWh connected in parallel
  • 5,000-cycle rating at 80% depth of discharge and 80% end of life, per Renogy
  • 200A continuous charge/discharge per battery (270A peak for 30 seconds), per Renogy
  • Self-heating on each battery activates below 41°F during charging and turns off above 50°F, per Renogy
  • Built-in Bluetooth on each battery with monitoring in the Renogy DC Home app
  • BMS with more than 60 fault alarms and protections, per Renogy
  • IP67-rated, UL94 V-0 flame-retardant PC/ABS housings

Why Renogy

The PRO series is Renogy's Bluetooth-equipped, cold-weather 12V battery line, engineered to pair with Renogy inverters, chargers, and monitoring. OffGrid Horizon is a family-owned authorized Renogy dealer — both batteries carry Renogy's US warranty.

Building a 12V Parallel Bank

These batteries connect in parallel only — per Renogy's manual, series connection is not supported on this model, so the bank stays at 12V and grows in capacity up to 8 batteries (20.48kWh). Good practice for a two-battery bank: use identical cable lengths and gauges to each battery, land system cables diagonally across the bank (positive from one battery, negative from the other) so both batteries share load evenly, and torque terminals to 70.8 in-lb per Renogy. Each battery keeps its own Bluetooth connection, so you can check either one individually in the DC Home app.

Warranty & Support

Each battery carries Renogy's 7-year US warranty — register both serial numbers with Renogy after purchase. OffGrid Horizon is a family-owned authorized Renogy dealer; call (302) 496-3554 for help with bank wiring, charger settings, or a warranty question.

Shipping

Combined weight is about 101 lb, so this order may arrive as two parcels or on a freight pallet within the United States. For freight deliveries, inspect the packaging before signing and note any damage on the delivery receipt — it is the single best protection for your claim. Contact us immediately if anything arrives damaged.

Frequently Asked Questions

Can I wire these two in series for 24V?
No. Per Renogy's manual, this model supports parallel connection only, up to 8 batteries. For a 24V system, choose a native 24V battery instead.

What does the bank total come to?
In parallel: 400Ah at 12.8V, or 5,120Wh (5.12kWh). Combined continuous discharge capability is up to 400A across the pair when the bank is wired for even current sharing.

Will both batteries show in the app?
Yes. Each battery has its own Bluetooth radio and appears individually in the Renogy DC Home app, so you can compare state of charge and health per battery.

Do they charge below freezing?
Yes. Per Renogy, each battery's self-heating engages below 41°F whenever a stable charge current above 6A is present, and disengages above 50°F. No manual intervention needed.

Should the batteries match in age and charge state?
Yes. Parallel banks work best with identical models at similar state of charge — buying the pair together, as in this 2-pack, is the clean way to start.

What if I need more capacity than 5.12kWh?
You can expand this bank to as many as 8 PRO batteries over time per Renogy, or build around a higher-capacity single such as the Renogy Core 12V 300Ah self-heating battery.
