CTEK D250SA 20A DC/DC Battery Charger

I bought this unit to maintain the leisure batteries in my 25 year old Hymer motorhome. The new batterries, that I had fitted (240Ah), are much higher capacity than the original one and too much for the old electrobloc system. The D250SA also acts as a charge controller for the 160 watt solar panels. The unit has worked well with no effort needed on my part. I would highly recommend it.

Fitted 3 years ago in my camper conversion, perfect for that if you have a solar panel. Fit and forget. Amazing service from Tayna.

This product was purchased to replace an earlier version which can handle 'smart' alternators (after wiring mods to the vehicle are done) but was not charging the auxiliary AGM battery correctly as the voltage supplied by the original unit was too low. This later version allows for a direct connection to the main battery and thus the alternator (with the addition of an ignition-switched clamped +15v enable feed from the fuse box - easily done with an appropriate 2A fuse tap after a suitable fuse is found in the fuse box). The unit arrived very promptly and was easy to install as it was a form-fit for the previous version. Some additional work was required to remove the original relay arrangement and add the switched enable feed. So far, there have been no problems and the revised charging voltage at 14.8v (about) is undoubtably casuing the auxialiary battery to charge more quickly. Don't forget - neither the alternator input or auxiliary battery charging ouput from the unit are reverse polarity protected and don't forget to fuse the charging output from the unit! The installation instructions are very clear.

I haven't used this yet bec. I have yet to get a battery to connect it to (so my star rating is for tayna.co.uk) Delivery was very fast and I liked that. Would definitely buy from here again.
