REDARC BCDC1225 DC-DC Battery Charger Review - How to PROPERLY charge caravan batteries!

I didn't even realise my van setup had a problem until I discovered how well this product worked!

If you've got a caravan or vehicle with a second battery system, you might be charging it straight from your vehicle. It's logical, and it's a cheap and easy way to do it. But it almost certainly WON'T fully charge the caravan batteries and it won't maintain the charge properly either. Discover why a DC-DC charger is a must for any dual / auxiliary / caravan battery setup!
