I agree. But I am now of the mind that the 100Ah is not worth doing as the 200Ah are such good value and give you 4x the usable energy of a 100Ah lead acid. Worth saving up the extra?

It says you can connect 4 together- even gives you a diagram 😉

Cheapest 200 amp battery I can find is £399 - 2 of the 100 s is £280 so if you add £10 for two leads you still save £110 ish - I’ll certainly be looking when these gels pack up- 2x 140 Victron at 11 years old 😉
 
I may be looking for a new battery for my motorcycle, it didn't want to turn over this morning, it currently has a two year old gel battery in it but it rarely gets fully charged as I don't ride long distances on it so I was thinking I might look for a lithium alternative.

In the link I gave they are £329 for a 200AH Lithium.
I prefer the convenience of a single 200AH rather than 2 x 100 AH but others may have a different opinion :)

Didn’t see that 👍plus I don’t know enough about lifepo4 fitting etc simply because don’t need it yet. At 11 years old batteries will need looking at soon-ish so your single 200 sounds a simple compromise 😉👍

Just gone back to look they also do a 300 amp one at £379 so only £126 ish per 100 amps = better value 😁

The prices of these are coming down so much, however I'd be wary of 'generic' brands that you can't find much information about.

For not much more you can get something like the Li Time which comes with important features like low temperature protection and which you can see in tear down videos from people like Will Prowse on YouTube. My first lithium setup used LiTime and I've been really happy with them.

The Haddocks might well be perfectly good but given the devastating nature of lithium fires, I'd personally feel happier spending £20-£40 more on something that's been ripped apart and scrutinised by someone who knows what they're talking about (i.e. not me :ROFLMAO: )

In fact, I've got a Fogstar Drift Pro 300Ah arriving next week which cost me £700 in the Black Friday sale (they were unsurprisingly out of stock as they currently retail at £820). Sure, it's a lot more expensive, but the important thing is that I trust it. I know they're built solidly and will stand being shaken around in a van for the next 10 years. I know the wiring is good, the BMS is good, the build is good, I trust the low temp protection and it's got lots of 'nice to have' features like bluetooth and integration with my Victron system.

As always it's a case of buy the best you can afford. I'd just want a bit more information on the Haddocks before spending my money on them.

To use a phrase I haven't heard in years: "You pays your money, you eats your choc ice...."

The heights not bad on the 300AH, but it's a fair old length 520mm, so under seat is a no. It's also a bit lighter than the Fogstar 280 A/H.

Asfaik the fire risk one is Lithium ion, not LiFePo4.

The discharge information is a little odd, and vague.

For example,
  • the 100Ah battery states Std/Max as 20A/200A
  • the 300Ah battery states Std/Max as 60A/600A
that seems both inadequate (Std) and highly suspect (Max).

Personally, I’d steer clear.

Be aware that lithium batteries will accept a lot more charge than head acid. Basically the lead acid has higher internal resistance whereas the lithium may overload your voltage rectifier/regulator and alternator. Talk to the supplier, it may be that for motorcycle use the internal BMS will control the charge rate.

I will be looking for a specific model compatible battery, I need to do some research before buying, lead acid variants are quite cheap for my bike so I can always fit one of those if my existing battery fails completely.
 
My bike used to hate starting on cold days and would frequently 'reset' the clock when trying to do so.

I was recommended the Odyssey batteries as they have more CCA (cold cranking amps) and a lifetime guarantee.

I'm on my second one now, nearly twenty years later! Never been on an optimate and has sat for months without being used and still fired up first time.

I've also heard good things about Motobatt although I've never tried one.

They are guaranteed for 5 years or 5000 cycles. My current ecotree 100AH have done 78 cycles and 3 years old.
Ecoworthy 100ah with blue tooth are now around £219 each.

I said earlier that I have not researched lifepo 4 so don’t really know about them apart from having lithium batteries for my Milwaukee tools ( very good and would not go back to ni-cads FOC 😁 Could you explain what the figures you quote are for ? In my simple mind I see the 300 one is 3 times more than a 100 or possibly 3x100 put together would give the same thanks Terry 😉👍
 
Yes the 300 is 3 x more than the 100 and yes you can put 3 x 100 together to give you 300.

The numbers relate to Amp Hours which essentially means that if you're using 1A of power then you can do so continuously for 100 hours (or 300 or whatever the Ah rating of the battery is)

Of course if you're using 50A of power then you'd only be able to do that for 2 hours with a 100Ah battery, or 6 hours with a 300Ah battery.

On anything that isn't Lithium you can only use 50% of that number before you end up damaging the battery. So a 100Ah AGM does technically have that amount of power, but you can only use 50Ah of it.

Theoretically sounds fine, but, expect that max rate to be limited to 1-3seconds. The max continuous will be 0.5C or 1C for a set time again. Giving those figures, looks like a marketing hook for punters. The Same like inverters 1000w continuous and 2000w max. Many don't realise that max rate is for a surge of 0.4-0.5 seconds.

I get that it’s the numbers
  • the 100Ah battery states Std/Max as 20A/200A
  • the 300Ah battery states Std/Max as 60A/600A
  • That I don’t understand ? Is it power drawn for say an inverter ? How does it compare with lead acid’s and other lifepo 4 batteries ?
