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
3.84kWh Motorhome Power Kit
3.84kWh of lithium, a 2,000W inverter and a 50A alternator charger — with a self-heating battery option. The self-heating variant is the reason to look at this kit rather than the standard one: it is what makes winter charging possible.
- 3,840Wh, 300Ah LiFePO4 at 12.8V
- 2,000W inverter
- 50A DC-DC charger
- Choice of 300Ah Core Mini or 300Ah self-heating battery
- Battery 384 × 194 × 253mm, 25.0kg, IP65
- Optional 3 × 200W ShadowFlux panels
The self-heating option is not a gimmick
Lithium iron phosphate will not accept charge below freezing — the standard pack's charge window starts at 0°C. In an uninsulated locker in a British February that is a real constraint: you drive for two hours and put nothing in. A self-heating pack warms itself before accepting current, so the alternator and the solar keep working through a cold snap. If the battery lives inside the heated space and the van is not used below freezing, save the money.
Sized for a proper motorhome
3.84kWh in one 25kg pack is a lot of storage in a single box — simpler to install and commission than two packs, and one set of cables. The 2,000W inverter handles a kettle, a microwave or a toaster, though not two at once.
Before you order
Four variants here: battery type crossed with solar or no solar. Check which one you are selecting on Renogy's page, and note the two battery types have different charge specifications.
