4 Jan 2021 - The Batteries

-

 I was keen to see if I could fit 3 x Victron 160 Ah Lithium Batteries in the same space as the existing Batteries 

  Existing AllGrand Battery New Victron Lithium Battery Can Victron fit ?
Height 210 mm 237 mm Yes, Victron is a little taller
Length 327 mm 321 mm Yes
Width 168 mm 152 mm Yes
Weight 36 kg - a guess 20 kg Yes, Victron is lighter

The existing AllGrand batteries have a model 6-GFM-100, a 12 volt 100 Ah battery. 

However, the AllGrand website has nothing about these batteries, I suspect they are a 6 x GFM 100 batteries in serial.  These are 2 Volt batteries, so the voltage maths works out, however getting those 6 batteries in the same foot print doesn't work, perhaps there are some packaging efficiencies in play.  See Allgrand Battery Backup Replacement Battery GFM 100.  

The Victron Battery I am looking at is Victron LiFePO4 Lithium Battery 12.8V/160Ah (mygenerator.com.au)

These are backup batteries, meant for UPS's so I find it comical that they're used in a camper. 

The existing batteries have the following notes on them 

Stand By Use13.5 - 13.8 Volts
Cyclic Use14.4 - 15 Volts

Ceduna 13 - Things we like and things we'll replace

 Things we like:  The storage space How solid it is Easy setup  The Victron setup is very good at what it does Things we'll fix soon The Trailer plug ie: This is the plug that controls indicators and brake lights etc.  I've found the plug to be poor quality and the connectors unreliable and was the original reason why the reverse camera failed.  Plugging it in today, I found that some of the terminals got pushed inside the plug itself. This is a warranty job. The annex The Dometic annex is unreliable. Not sure what we'll do there, maybe a warranty job too. Move some electricals around Position of stereo Position of USB charger. Things we'll replace in the next year Light Switches: Will replace with a wireless light base station and install remote terminals near the bed, on the inside near the door at a good height for internal use and outside in the foldout workbench The outside Surround Lights A single switch controls two different outside lights (called surrou...

 I took the camper down to Berrima for a few nights to test it out and get a  Window Blinds Overnight they pop down an inch Gas/Electric Hot Water Heater It's a storage tank heater.   In my own minds eye, I figured the hot water heater was an instantaneous heater so it was a surprise when I discovered that it was a storage tank.  Not a major issue as the hot water is a nice to have rather than a Took about an hour to heat the tank with electricity, I never had a shower in it so the juries still out on how long the water lasts for.  I also didn't have any gas, so I couldn't test out the gas hot water heating.  Position of the light Switches The position of the light switches are annoying.   I'll probably end up installing a wireless light controller, something like  Sphere Wireless Lighting - Coast to Coast RV   Say Wot ? The main lights use 5 amps !!
