If you’re after a smart bit of kit to keep your batteries in tip-top shape, the CTEK D250SE is well worth a look. This clever charger takes care of both 12V lead-acid and lithium (LiFePO4) batteries, serving up a hearty 20 amps of charging power. Whether you’re off exploring in your campervan, hauling in your truck, bobbing about in your boat, or heading off the beaten track, it’s got your back. Plus, thanks to its built-in solar panel regulator with MPPT tech, it squeezes every drop of power out of your panels – just the ticket for anyone going off-grid.
Key Features
- 20A Charging Power: Packs enough punch for batteries ranging from 40 to 300Ah, so you’re covered whether you’ve got a compact setup or something a bit more heavy-duty.
- Solar Panel Optimisation: The integrated MPPT solar regulator makes sure you’re getting the most out of your solar – so you can top up your batteries efficiently, even when the sun’s playing hard to get.
- Dual Battery Charging: Designed to look after both your service and starter batteries. Once your leisure battery’s full, it automatically diverts power to your starter battery, so you’re never caught out with a flat.
- Smart Alternator Ready: Plays nicely with all types of alternators, including the newer smart ones you’ll find in modern motors.
- Built-In Temperature Sensor: With its temperature sensor, it adjusts the charging rate depending on how hot or cold it is, so you don’t have to worry about frying your battery in the summer or undercharging it in the winter.
- Top-Notch Safety: The D250SE is built to take a bit of a beating – splashproof, dustproof, with reverse polarity and short-circuit protection, plus it delivers clean voltage to protect your electronics. No nasty surprises here.
