Is this the best UK Life4Po leisure battery. (1 Viewer)

[PhilandMena]

I saw this battery recommendation thanks to Moto GBR The claims on its website are very impressive and watching the U Tube videos where it it tested, pulled to bits and given a thorough examination and all receiving a Thumbs up, might be of great interest to members who are considering a grade A lithium battery that can be maintained on a lead acid charging profile and is under £400. for a 100 AH battery with a 10 year guarantee.

No not really the 560ah version with it's continuous discharge rating of 200A will not even run a 3kw inverter.

Ah.. but for people who have no need for an Inverter, (like me) they seem OK.

Thanks Martin. Is there any other aspects you find fall short ? A 3 Kw inverter is a bit of a beast ! Mine is only 300 W. Mena says hello.

It's rare that my house needs 3kW.

Plenty of us on here already have Fogstar batteries and are happy with them, i run my microwave through a 2kw inverter on a 300ah fogstar and have had no issues so far?

I am sure they are great and certainly better value than ours but I was just trying to answer the question in the post title "Is this the best UK Life4Po leisure battery" I am sure that they work for most/lots of people. We have a 3kw inverter and the kettle takes 2200 watts, microwave and coffee machine take about 2400 watts.

Maybe we have more electric stuff than you but the kettle plus anything else would be over 3kw.

What inverter do you have in your van Martin?

Better than OK would be my guess , I was surprised looking at the spec though that they all quote the same maximum amps draw, maybe the answer for power hungry users is to run two or more in parallel if that would increase the maximum amps allowed, a question for somebody using more than one I think.

 

[funflair]

What inverter do you have in your van Martin?

Buttner (Dometic now) Morelo used to fit Mastervolt but they said it was too complicated for a lot of users and service centres had to reprogramme the system when hardware was changed so they moved to Buttner for inverter/charger, solar charging and B2B booster as well battery monitoring, I thought the PWM solar was a waste of power so swapped out to Victron and recently added Victron battery monitor/shunt as it's more accurate than the Buttner.

Phil, the Fogstars get good reviews and the company is the main importer for EVE cells which are amost the best.
I will be using Fogstar for the next van either 2 x 230 ah or one 460ah.

If you want the best get a Super B but that will coast around £1600, for a 100ah.

If you want a high discharge for reasonable money, that’s roamer, if you want a reasonably priced battery with decent warranty and pretty good quality, then fogstar.
The example given above with the 560ah it’s unfair. That battery can discharge 400a with ease, it’s the bms that’s limiting to 200a. And for good reason, if you need higher power, you should go up in voltage, not in amps.
I have built my own with 100a I can discharge 5kw, but at 48v.

 

[Lenny HB]

Buttner (Dometic now)

I'm looking at fitting a Victron Multiplus 3000 in the next van. It is 3000va so 2400 Watts so should get away with 200 amp max discharge but may go for the 2 battery option to be safe.

I get the increase the voltage bit OK, but what is it that dictates that the BMS is limiting all batteries to 200 amps? is it the internal wiring ?

Two batteries Lenny it’s a no brainer, you will put less stress on each bms. These bmses are mosfet based swich, means all current passes trough the board. Less stress and less heat longer and more reliable life. Always spec double for what you expect to be peak power.

Many things, including wiring. Transistor bms can only go up to a point where safety and cost spirals up. There are bms with external controlled relay like REC , Orion, but they cost over 1k. For big power it’s worth it.

Would I be correct in thinking two 105 AH Frogstar's would be better than one 230 AH Frogstar. I cant figure out which is the best option and why.

I haven’t looked at the spec of those you mentioned. But if the 105ah comes with 100a bms, and the 230ah comes with 200a bms, then the 230ah it’s better as you manage less cell count with same discharge capability.
Only chose two batteries when the sum of discharge is greater for same capacity.

I don't see many alternatives if we want a cup of tea

I only use a 1kw kettle as well, but I m not going to criticise someone who wants a bigger one because imo the great thing about all this stuff is we have the ability to set it up to suit our individual requirements.

I thought it was actually about using more than 3kw at home Jon, I know you like your baby kettle though

Lenny ive just looked the Victron up as we should be getting our new Carthago in a few months and am considering what to fit with our Fogstar 230a ,its a hell of a lot of money, do you use that much electricity to make it worth while ?

Sorry I didn't mean to come across as suggesting you were being negative. Some of us can only dream of having the set up you have, me especially!! So sorry if I gave you the wrong impression!

I bought a new one at Gib on the way out, Ive just checked and its only 650w but boils 2 mugs pretty quickly and reliably clicks off when its done. Using solar a lot on this trip, havent plugged in yet although had to use the gas kettle twice not bad for over 40 days.

Any chance of showing a picture of it, or the name and model, please

Amazon product.

Only downside is despite having a union jack on the box it was actually made in China

So it can’t be maintained on a lead acid charging profile, not according to your charging profile which is a lithium profile?
