Lithium batteries

I,ve got 3 x 120 a/h ITechs and 1 x 100a/h Renogy. All perform well and are 500% better than the AGM,s they replaced. Both have a very good reputation and various You-tube clips show more praise. Not the cheapest but if you want A grade cells, good BMS and quality you normally have to pay for it. Make sure you also get a good battery monitor that can tell you the voltage, amps used/gathered etc.etc.

Dont buy anything that doesnt list internal resistance. Low resistance means low temperature, faster charging etc, repurposed lithium has a higher resistance. Many batteries dont bother to advertise too many specs

Take a look at the new REDARC GoBlock setup. With the Dock it is secure and wired in just like a second battery system but in this instance the Block can be easily removed and used by itself for many things, such as running a CPAP machine in a tent. But you do need an inverter for that if you don't have one for your CPAP machine already. Plenty of other examples other than that one

Make sure you check what the maximum discharge current is, some of the cheap ones are only 50 amps, the higher the better.

Have a look at the range available from Lithium Battery Wholesalers, on Facebook. Good range, good charge & discharge rates, competitive pricing & usually freight free.

Hi Ray,

From a lot of the on line reviews, Renogy seem to get all positive reviews. They are well priced at around $800 for a 100 amp battery.

itech lithium batteries are NOT waterproof. Colleague fitted them into his Lotus Caravan Chassis mounts They failed 18 months later. Returned them for investigation, was told they had internal water damage...no warranty claim. He claimed manufacturing fault...but not accepted by itech. Beware.

I agree with many of the responses..but the bottom line comes down to:
1/. How deep are your pockets?
2/. What are you immediate and future plans for your set up?
3/. Do you really have to go for lithium..for lithium's sake..keep up with the Jones etc..so to speak.
Question 1..
Your price range can be from $600 to over $3000..each of the lithium batteries mentioned in this thread cover this huge price bracket...Renogy from about $700... Redarc..$2800 and then you have the many many brands in between..
Question 2..if you have a set up..a 12v compressor fridge, say 50Ltr +, few lights, couple of charging points and you camp couple of times a year..then a $500 - 120Ah cheapie lithium battery might be the go..I know of a couple of mates who have the $600 Voltex / Atlas / Encore 120Ah lithium .... they charge them with a basic vehicle solenoid ignition system but they know the risks of this way of charging, if they get 5 years out of the battery, well it's no skin off their nose, so to speak..BUT..if you want to run all the mod cons' and go off the grid for days at a time, have remote monitoring of lights, compressors, fridges..etc...I mean go the whole hog....then $5k is not out of the realm of reality.

Single fridge is fine with a 100Ah Lithium. Add a solar panel and you'll never run out of power.

I currently own 4 of the Sunyee LiFePO4 purchased off EBay. Two have been running for 15 months in the Troopy and two for about 12 months in the caravan. They perform faultlessly. In the Troopy I often run two fridges - one as a freezer. I also run a 1500W inverter which pulls 120A when running a coffee machine or hair dryer and is also used for other stuff. From memory the standard discharge current for each battery was over 100A. Actually ran a fan heater where it pulled 170A - just for a test for about 30 secs.
With Lithium, you pay for the battery and you also pay for the brand. I'm happy to skip the name brand. The Sunyees cost me $400 each. There are stacks of so called "cheap" Lithium batteries out there - I've fitted a couple of the VoltaX brand ones in mates vehicles and caravans and they have been very good also.
