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!

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.

Fast delivery thanks

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

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.

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 to always be 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.

We install this kit in our campervan builds here at Leitholm Campervans Ltd. Easy to install/set up too. Comes with a good installation instruction manual if you’re not 100% sure about the wiring. Links well to the smartphone via Renogy M1 and the BT2 Bluetooth unit. No complaints from us.
