How buying this works

Roam Wired does not stock this item. The button above hands you over to the seller's own shop, where you place the order, pay and arrange delivery directly with them. Nothing is added to a Roam Wired basket, and we never see your payment details.

We list it because it is the part our calculator would specify for a build like yours, not because we make the most on it. How we make money

Delivery and returns

Delivery cost, delivery time and the returns window are set by the seller, not by us, and Roam Wired's own £10 / free-over-£250 UK delivery does not apply here. Check their delivery and returns terms on their product page before you order.

Your consumer rights, including the 14-day right to cancel a distance sale, are against the seller who took your order.

Warranty and support

The manufacturer's warranty is handled by the seller you buy from. If something fails, raise it with them and quote their order number — we cannot open a claim on your behalf.

Overview

Pro S1 12V 120Ah LiFePO4 Battery

120Ah, 6,000 cycles, IP67, and a seven-year warranty. The Pro S1 is Renogy's long-life pack — rated for roughly twenty per cent more cycles than the Core range, sealed to IP67 rather than IP65, and reporting over both Bluetooth and CAN. Also sold as a 240Ah.

  • 120Ah at 12.8V nominal
  • 6,000 cycles to 80% depth of discharge
  • 150A continuous discharge, 350A peak for 30 seconds
  • 120A maximum charge current
  • Bluetooth and CAN communication
  • IP67, 13.4kg, 325 × 189 × 188mm

What 6,000 cycles is worth

Cycle life only matters if you actually cycle the pack. A weekender doing thirty trips a year will not see the difference in a lifetime. A full-time build that takes the bank down and back up most days will — at one cycle a day, 6,000 cycles is well over a decade before you are at 80% of the original capacity. If you live in the van, this is where the extra cost goes.

CAN as well as Bluetooth

Bluetooth is for your phone. CAN is what lets the battery talk to a compatible inverter-charger or controller directly, so the charge profile follows what the BMS actually reports rather than a preset. If you are building around Renogy's own kit, that is a meaningful integration; if you are mixing brands, check what your charger speaks before counting on it.

Before you order

IP67 rather than IP65 means it tolerates temporary immersion, not just dust and splashes — relevant for an underfloor or garage locker that occasionally gets wet. The 240Ah version is 405 × 244 × 188mm and 25.5kg, so check the space if you are considering the step up.
