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
Core Mini- 12.8V 100Ah Lithium Iron Phosphate Battery
100Ah at 12.8V, 9.9kg, in a 229 × 138 × 213mm case. The small end of the Core Mini range and the sensible starting bank for a weekender — or the building block for a larger bank, since it series and parallel connects up to 4S4P.
- 100Ah rated capacity at 12.8V nominal
- 5,000 cycles to 80% depth of discharge
- 100A continuous charge and discharge, 300A peak for 5 seconds
- Series and parallel to 4S4P
- 9.9kg, 229 × 138 × 213mm
- IP65, M8 terminals, 10–12 N·m torque
Where 100Ah lands
1,280Wh of nominal capacity is a weekend of compressor fridge, lighting, phones and a laptop without much thought, and rather less than that once a diesel heater joins in. If you are converting for long trips or full-time, treat this as one of two rather than the whole bank — or start with the 200Ah.
Building a bigger bank
Renogy rate these for up to four in series and four in parallel. Parallel packs must be matched — same model, same age, same state of charge at commissioning — and want equal-length cables to each terminal so they share current evenly. Get that wrong and one battery does most of the work and ages faster.
Before you order
Charge window is 0°C to 50°C, so no charging below freezing. Terminal torque is specified at 10 to 12 N·m; use a torque wrench, because a loose lithium terminal under 100A is a fire risk rather than an inconvenience.
