DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT(New Version)

I use mine to charge my LifeP04 battery which it"s doing very well. Thankfully my battery has Bluetooth connectivity, so I can see what the charger"s doing.It gives a very reliable 20 amps. If I"m running my car fridge and that kick"s in then the charge will show 17 amps on the battery. At first I thought that there was a problem but then I realised.I can"t see the fridge while driving so it wasn"t that obvious.My car once had a flat battery and this confused the unit. I had to disconnect all the wires going into it to clear the fault light. I also wired it to a switchable live signal because I don"t want the leisure battery always full. They last longer if you keep them below 90%. My BMS has an on screen switch to stop the charge but, it also stopped the % used from working.

Overall I"m really pleased with this little bladeless fan. It moves a good volume of air and does a good job at keeping me cool. I love that it"s very quiet, so it"s great for my bedroom. It offers a good variety of speeds, ranging from a light Breeze to pretty strong air flow. The sleep timer is also great since it allows me to set the timer before I go to bed, and it"ll automatically turn itself off during the night and save electricity. The remote control feature is also great for my purposes since it allows me to control the fan from the comfort of my bed.I think it"s a good value for the money and I would buy it again.

Good communication top quality item great delivery and service Top seller A++ highly recommended

Fast delivery thanks

brilliant

Love it. But in the UK, PV output isn't great. So added a 60A rated relay to cut off the PV input, controlled by the D+ (engine on) feed on my Sprinter W906, so can charge LiFePO4 batteries at 50A from ALT input (need appropriately sized cable from starter battery) when the engine is running. If Renogy added this already, or adjusted the charging algorithm to accommodate such scenario (low PV power) it would be perfect. Haven't observed any overheating issues, but may add a 12v computer fan to help shift some air across the rear just in case. Also would like an option to dual charge [from PV] both starter battery and leisure battery (eg before leisure battery is full) in case static for some time to keep starter battery topped off, but would need dual charging logic (lead acid vs LiFePO4) so maybe a bit much to ask.

Been using the 50 amp charger for almost 2 years to charge 2 AGM batteries, No issues to report for these batteries. Bought a 170 lithium battery from renogy 4 months ago and one major issue shows up every-time. The charger will overheat and go into error 6 mode when driving using the alternator. Why it does this, the lithium battery will take the full 50 amps until it reaches 14.4 volts. I use a solar cut off switch to gain the full power when driving, this is causing an overheating issue and is the same when the solar has turned itself off when dark. The charger is overheating in Scotland in Mid winter and where the charger sits its about 15c and it has plenty of air. Renogy you need to have active cooling like a small inbuilt fan to fix the overheating? I use a small fan to help it stop overheating. The large terminal screw bolts are far too short for large cables and is a struggle to get the cables screwed down, All you need to fix this problem are longer terminal screw bolts. In countries like the U where the sun is low or never out at all, you need to add a solar power cut off switch, this will fool the charger in thinking its nigh so will go from 50% 25 amps per 50 mode to 100% mode. So if you leave the solar on on a cloudy day, yo will get 25 amps from the alternator and maybe 1 amps from the solar, you are then losing around 24 amps. I would like to see the charger use an algorithm when driving, so it measure the solar output which would gain what ever it needs from the alternator. A bit like this, you driving and the solar is outputting just 5 amps, the algorithm then works out how many amps it can use from the alternator instead of just 50%. so would be 45 amps from the alternator and 5 from the solar making up the 50 amps. I give it 5 stars because I have fixed all the faults apart from the short terminal bolts, but TBH I shouldn't have to fix any!

Perfect looks really good and fit perfect

This is a great piece of kit that is very easy to wire up. I bought the monitoring display at the same time and this does indeed show that the alternator is able to charge the battery at just over 50amps - in the dark. If the solar is producing any power at all - it splits the charging capability equally between the two sources. This is clearly not a problem when you're parked (not running your engine) or driving at night - no solar. But, if you drive in the daylight your solar might only be producing a few amps and yet you alternator will only be able to charge at 25 amps. The system prioritises solar but in my opinion it would be better if it prioritised the alternator. I solved this problem by installing a switch to isolate the solar when driving and in this way the alternator side produces and charges at 50 amps. I've only got 125 watt solar panel and the best I ever see is about 7 amps. So driving in full sun and an empty battery the best the charger would put in is 32 amps. Isolating the solar solves the problem. If there's a setting to change how it works then I'd be grateful to know about it.
