Victron Energy Blue Smart IP65 Smart Car Battery Charger 12V 15A, Trickle Charger for Car Battery and Desulfator for Motorcycle, ATV, RV, Lithium and Deep Cycle Batteries, UK

My off grid Solar Panel setup has two 100ah LifePO4 Batteries with built in Battery Management Systems (BMS). The BMS protects the batteries, including the battery temperature, overcharging or the voltage falling too low/undercharging (Under Voltage Protection UVP). The problem is that when the voltage falls below the trigger level, the BMS UVP steps in and cuts off the battery voltage and from then on, the battery voltage reads as zero and most Battery Chargers that are 'supposedly' suitable for LifePO4 Batteries, will not recognise this scenario/state and as such, will not charge the battery, no matter how long you leave it connected. However, when the Victron Energy Blue Smart Charger is connected to the battery, it initially carries out a test and if there is no voltage, it will automatically reset the BMS UVP and start the charging process. For this reason alone, this battery charger is worth paying more for. This Victron Charger oozes quality, it is well designed and constructed and is simple enough to use straight out of the box. You just need to select the battery type and leave it to it. Once connected it carries out a quick battery test and within a minute, it is pumping up to 15 amps into the battery (if required). The Victron App is very useful in that you can view the charging process from a short distance and alter settings, but BE AWARE that you do need to be quite close to the Charger, i.e., you can't check it from a different location. It will reach from my house to the wooden garage but no further. An Added Bonus with this Charger, is that it can also be used as an adjustable Power Supply which is really useful for my Solar Panel setup (shown above), in that I can leave the Charger connected (in Power Supply mode) to my batteries whilst being plugged into the Grid Mains, and if the Batteries voltage drops below a pre-set voltage, say 12.90 volts, the Victron will step in and start supplying power but will then stop supplying once the batteries voltage is above 12.90 volts. To conclude, no major issues to date but I will edit this review if necessary. It works really well and I have no hesitation in Highly Recommending this upmarket charger.

Like everything Victron that I have bought it works perfectly without issues. It charges without overcharging the battery, can monitor within its blutooth range. And runs cool to the touch. It maintains battery voltage below the gassing rate after charging which is essentially as most batteries can’t be topped up with distilled water.

I plugged it into my flat T2 VW camper van left it to do its thing, checked every so often on a handy app on my phone and it told me when it was fully charged, it works a treat! Also you can keep it plugged in when you are not using van and it keeps it topped up. It seems very well made and a great price. I’m very happy with this bit of kit.

Great product, does just what’s required. The reconditioning feature, lifepo4 and Bluetooth make it very useful

Quailty products, brought as had a flat battery on my VW camper, did a great job and the app worked well. Good crocodile clips meant easy to connected to both positive and earthing point without need to disconnect battery

A good product solid quality part. Lost one star as for price it should come with a case.

good quality and works really well

The charger is exactly as described and arrived promptly and well packaged.
