Armortek

Got a link to where we can buy direct?

Kian / Monique -

Shame it fell through, but well done for trying !

Simon (and others) -

These are potential LiFePO4 suppliers in the UK (other suppliers may be available )

Hope this helps. No personal warranty given or implied !

All the best,

Chris

The manufacturer we are buying our batteries from does not deal with private sales - we had looked at this option for you guys.

Perhaps those who run LIFePO4 batteries can recommend where they bought theirs from as Chis has done above.

The options for purchasing appropriate batteries are many. eBay, Amazon, Banggood, AliExpress and many others. I sent away for my last group of cells. Took 2 months but the price was less than half what a local company wanted for the same cells. Anticipate your needs/requirements and purchase in advance. My last group was 8 100AH cells I intend to use for my JagdTiger.

Would it not be viable to add a percentage mark up to the original price to cover you for any potential issues with defective batteries?

With the way some societies (names withheld) have become so litigious I wouldn't want to take the risk if I were
Armortek. It might not even be from the original purchaser but even from a second or third hand buyer or family.

To make a few bucks/pounds/euros, or none at all isn't worth it. I've not sold a model in years but if/when I do the batteries won't be part of the deal...

Hi everyone
I bought the batteries for my PZ III here:
https://www.lipotech.net/newstore/
These are these, I've been using them for over 10 years:
https://www.lipotech.net/newstore/lte/1 ... -22ah.html
they are also found similar or the same from other sellers.
they don't have BMS,
if you want it it should be added,
I don't use it,
I use radio telemetry and do the balanced charge with a specific charger at 1C at the fairs at 1/2 C at home.
regards
Marco
P.s.
I don't use the BMS at my own risk, aware of what I risk

Well, the thought was good. Thanks for trying.

The folks in the US are still interested.

Hi Kian and Monique

It's a shame it fell through but thank you very much for trying.

Kind regards

I somehow missed this and I would have been sad to miss out.....I am just now starting to think about batteries.

Anyone have opinions about this brand: Eco-Worthy

https://uk.eco-worthy.com/collections/1 ... te-battery

Not quite as good constant current, but 30A seems good enough. About the same in all other aspects, including price....and comes with a BMS built in.

Hi all,

especially a BMS in a 12 V battery would not be my first choice, when 24 V are needed. Using 2 batteries you have to charge them individually, which is somehow inconvenient in my eyes. If a BMS is desired, it should be a 24 V version combined with single cells or a 24 V battery with built-in BMS. In Germany e.g. I-TECC offers such cells and BMS versions in several sizes. They also complete the whole set to a battery if desired.

Hi,
a friend of mine is using these batteries on King Tiger, Elefant, Tiger,
he is very happy with it

I'm using a pair of those in my King Tiger. So far this seem quite sufficient. I paid a tad more for mine.

I bought that brand (not that particular battery) for my Pershing off of Amazon. Two 12 volt batteries and I do charge then individually. So far so good.
Next time I think I will try a single 24 volt but they are not as common as the 12 volt batteries. I don't recall why I went with the two 12 volt, size or cost?

Why not buy 8 LiFe cells of about 30 Ah each, some connectors and a 24 V BMS, if wanted? The assembling is no rocket science, indeed. Here two packs of 4 cells of 40 Ah each, seperated for easier handling.



Here the wiring of one pack; the other pack is wired equally. With this kind of wiring one can use either a BMS or another kind of monitoring the cells, just as desired. With this model I'm using single cell monitoring when charging and discharging, without a BMS.



Another model of mine has a BMS, and at another application (emergency power source for my home) I'm even using a combination of charging without BMS and discharging with BMS, because my Unsi charger has a finer cell monitoring and more balancing current than the used 24 V BMS with 150 amps continuous current and 500 amps peak current.
