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
Motorhome Power Kit 3.84kWh
A battery and an inverter as one purchase, in two capacities. Choose 2.56kWh or 3.84kWh and you have the storage and the mains side of a motorhome system settled in a single order.
- Choice of 2.56kWh (200Ah) or 3.84kWh (300Ah)
- LiFePO4 at 12.8V nominal, IP65 rated
- 5,000 cycles to 80% depth of discharge
- 300Ah pack 384 × 194 × 253mm, 25.0kg
- 300Ah pack 150A continuous charge, 200A continuous discharge
- Pure sine wave inverter included
Which capacity
2.56kWh suits a weekend van or a motorhome that moves most days — roughly two to three days of typical use before you need input. 3.84kWh is the full-time figure: enough to sit still through a dull week without rationing. The larger pack also accepts 150A of charge, so it refills faster when the sun does appear.
One pack, not two
Both options are a single battery. That is worth something at install: one set of cables, one set of terminals, no matched-pack commissioning and no wondering whether both are sharing the load. The trade-off is that 25kg has to go in one place, and that place has to be inside the heated envelope — charging stops below 0°C.
Before you order
The two variants pair different components, so confirm on Renogy's page exactly which battery and which inverter rating your chosen option includes before you size cable and fusing.
