If you mean a 12V leisure battery box for a caravan, motorhome, boat or campervan, these are the options I'd look at:
- Numax Group 24-31 Battery Box HM318BK - £29.99 (Alpha Batteries) - Attwood Standard Battery Box - £11.00 (PRIMA Leisure + others) - NOCO BT31S Group 31 Heavy-Duty Battery Tray - £25.12 (BBL Batteries + others) - Cocoarm Marine Battery Box - £26.56 (Amazon.co.uk - Amazon.co.uk-Seller)
- Numax HM318BK - good straightforward enclosed box for roughly 75-135Ah batteries; currently around £30. Top Choice - Attwood Standard - inexpensive, simple option; particularly attractive if you just need secure containment rather than built-in electronics. - NOCO BT31S - a heavy-duty tray rather than enclosed box, useful for larger Group 31 batteries. - Cocoarm - enclosed ABS box with strap, aimed at marine/RV use.
If you tell me your battery size (e.g. 100Ah/110Ah/120Ah), battery type (AGM/lead-acid/LiFePO4), and whether it's for a caravan, motorhome or boat, I can narrow it down to the right UK box and check current prices.
