Renogy 100Ah Lifepo4 V BLUETTI EB70

[shropschris]

My Agm is getting old was looking into a renology 100ah Leisure battery, then I notice the price on the BLUETTI EB70 so which one would give more bang per buck?
The Bluetti would only get used in the van I guess it would be easy to take with if I sell up that said however in the current climate I will keep the van for at least another year .
A plug in and play folding soar panel would work on both for park up top up Bluetti also has this on offer at the moment

So what would you buy ?

 

[Dellmassive]

depends on your needs.

EB70 has half the capacity of the Renogy, but is a all-in-one solution.

+++

BLUETTI EB70 = 716Wh - worth of power

Renogy 100ah = 1200Wh - worth of power

+++

The renogy you would need to add the charger and inverter to get the similar like for like comparison.

Not sure on the bang for buck but I've just bought the EB70 and its a great bit of kit. Currently using it at home to test how long it can power stuff for. I've had my laptop plugged in to it for 8 hours yesterday and 4 hours today and so far its used 60% battery (on the Bluetti).

if it was me . . . . id get both.


have the Renogy fitted in the van for the leisure setup.


then get the EB70 for mobile and to backup the vans leisure system.

Thanks chaps , The van is already set up it just needs battery swap I think that is the way forward
I guess I just need to add a solar in feed clip to the battery to plug something like a Lensun 100 w in now and again .
As ever I will read your info Dell and choose a solar panel
thanks chaps its always very helpful to hear from folks who have done it

 

[shropschris]

I used Dellmassive's , link saving 6%from the already bargain price Renogy . Cold beer all summer thanks for links and advice .

Just remember charging voltages/profiles vary between battery types so just make sure your setup is correct to maximise your new lithium

 

[shropschris]

Cheers Pauly , I did that

@Dellmassive Do you happen to know why the Bluetooth version of the Renogy 100Ah is cheaper than the 'Smart' version? Is the Smart version better somehow? Also, does the bluetooth version fit under the driver's seat?

 

[Dellmassive]

@eirej

im not sure, its different cell tech and a different BMS, and case design.

maybe they doing the new version cheaper as a promotion?

This is the current Renogy offering

Lithium Battery,Leisure Battery,Solar Panel Battery|Renogy UK

Lithium batteries have a longer life cycle compared to AGM and GEL batteries. The 12 volt batteries are the solar batteries most cost effective.

uk.renogy.com

100A smart = £499 + £29.99 BT2
100A smart heated = £599.99 + £29.99 BT2

100A w/BT = £459.99

If have one under my seat ,we have been away for a week,no hookup and it's ace ,fridge lights and heated blanket has hards made a dent in it

@shropschris that's excellent....
I love it when things work out for people,

Got a few pics of the setup?

How's it charged?. Got an inverter?... Got any monitors?

I don't have any photos, running a split charger ,no inverter as yet that's next .
Just a couple of 12v sockets and a small double 3 pin plug

 

[Dellmassive]

How do you power the heated blankets and 3pin plug? If no inverter..... But running off the Renogy battery?

 

[shropschris]

Ah sorry yes it's an 150 w double plug bestek inverter is all we have at the mo .
I will.pop a more powerful inverter on when I get time

 

[Dellmassive]

Gotcha...

Any idea on the wattage of the heated blankets?

I looked online at 4* blankets and none of them stated the wattage..... But all were 240v.

 

[eirej]

I've been in touch with Renogy. I'm impressed with their honesty and level of communication. Makes me feel more confident in choosing them.

 

[Dellmassive]

That's good....

So basically what we thought before..... Though it's good to have technical confirmation..

I have all three versions.

Smart heated and non heated, plus the newer W/BT version.

They are all very good, and don't power down or sleep..... Which is good for long term monitor ING.

I am an Electrician and currently halfway through my engineering degree, but I am definitely a bit of a noob with DC.
That being said, regarding the Renogy Lithium batteries:

• For me, I think that having the 'Smart' version represents better value as it has 2 years extra warranty and apparently has twice the life span.
• I am not convinced about the necessity of a Bluetooth dongle as an optional extra. I'd be more inclined to use a more accurate shunt monitor with an alarm feature to warn of low charge. Some shunts even have a relay feature so that the alarm will coincide with an output that could be wired through a relay to switch out the battery outgoing cable. I don't think I would ever have to access the BMS? I suspect that firmware updates are possible via the rj45 cable, though I can't confirm this. As the product has been on the market a while now, I imagine any bugs are dealt with already. This way, if I install an isolator on the outgoing of my battery, I can just switch it off and push the sleep button on the battery and hey presto, peace of mind for parking up for a few weeks without phantom discharge.
• I like that there is a plug in button to turn it into shelf mode! I don't want to have to fool around with things too much or apply certain current to wake it up etc.
• I don't see a need for me to have the additional IP protection.
• I like that it is a tad smaller. I may be able to fit some wiring or narrow modules down its side under the drivers seat. Also, it would make it slightly easier to find space in the cabinetry for another (the same) battery to use in parallel if I feel I need more juice.

Re the heated version, I believe the shunt monitor also has temperature probe terminals. I imagine that this will be then configurable to trigger an alarm at the critical temps, and then wire the Shunt's built in relay (Victron) to disconnect the necessary incoming / outgoing. Ireland gets chilly and often freezing, but I suspect it it wouldn't go down past the safe discharge temp. If it does go below safe charge temp, I could have the charging cable on an isolator, run the van for a while to warm up, then turn on the isolator to start the dc-dc
