Hi guys, I’ve attached this chart I came across after finding that lots of people are having problems with overheating. It entitles anyone to send their unit back for a replacement unit without question if the serial number predates those in the chart. The way to date them is from the serial...

And the high temperature, 43 degrees? How long will an Orion last running at that temperature?

Thanks for this, I’ve just checked with a digital thermometer while charging (plenty of ventilation!). It very quickly got up to 43 degrees centigrade and settled charging at 25.8 amps. Because I have now provided good ventilation, what could cause this? There is a cavity behind the cupboard...

Thanks again guys for getting back to me. I went up to the motorhome today (keep it on a nearby farm). As there is no hook up, I brought along my home build lifepo4 battery, 2000w inverter and a hook up lead. Using the onboard 40 amp mains charger it didn’t take long to get my 200 amp lifepo4...

Thanks Chris that was very helpful.

Thanks for replying, the thin wires at the bottom of the picture may be misleading, they go to a 12v thermostat and only serve to activate a 10 amp heater pad below the battery if the temperature ever dropped below 5 degrees centigrade. The wires going into the Orion look about as big as you...

I can’t figure out why the Orion is getting so hot while charging, the cables don’t seem to be too hot, maybe the guy who installed it has done something wrong?

I think we’re at cross purposes here guys, I showed you a picture of the Polinovel app for my battery. It reads 13.5v not 15.5? The reason I wanted folk to see the snap of this app was to see the amps while the engine is running and how they settle to 25 ish per hour after being given plenty of...

Thanks again guys, struggling to maintain our battery at around 65/70% with no solar, (12v 4s lifepo4 battery). I’m Lucky to pull 25 amps/hr after 25 minutes with this Victron 12-12/30 b to b smart charger. It was hot to touch after 20 minutes. 15.5 v is high for lifepo4?

Guess what guys, I decided to remove all surroundings away from the Orion unit (plenty of airflow with an outside temp of 7degrees centigrade). When the unit kicked in I was getting 29.8 amps which I could live with and drove for an hour stopping occasionally to check things out without stopping...

Thanks guys, I have been kindly supplied with a detailed wiring diagram to help me fit another unit, but from what you are saying the heat problem might become worse? The space I have the unit in is covered over the top with a removable seat and sliding door to access the space below the seat...

Sorry the batteries internal sensor showed 18.7 degrees centigrade while the engine was running.

Thanks smoothJoey and mikefitz. To explain further, by ‘fade’ I mean the charge current drops to 25-26 amps/hr which impacts greatly during the winter when very little solar is available. I know that cabling and altinator are up to a second unit, but the only reason so far that looks close is...

Can anyone tell me why this charger fades after around 20 minutes and the charge drops to about 26 amps/hr? Also can anyone provide a wiring diagram to show how to run another unit in parallel in order to make up the loss? Thanks.

I bought from Quality Source Ltd. I got the 200 ah Polinovel lifepo4 with smart bms and a 40ah mains charger (seem to discontinued). Both have been flawless. Look on YouTube for John & Mandy, they are living full timers currently touring Europe. Watching them convinced me to go with Polinovel...
