Fourvolt.com. Cheap deal on Lithium?

[Jev88]

Hi. Anyone used this USA company?
$379 for 12v 100ah?

Plenty of online comments back in Feb saying it’s a scam!!

If it's a scam it is a very long running one.
Been seeing the adverts and discussion on FB for several months.

Buy one then you can let us all know if there is any truth whether it’s a scam or not

I am verty tempted to be the guineapig........ Just feels abit extravagant at the moment...... They also argue (and other sites too) that a 70ah LiFe battery is same performance as a 100ah normal 12V leisure battery? I am guessing that refers to Lithium batteries tolerating a far deeper discharge without damage?

That’s correct, you can discharge lithium’s down to below 10% without any damage so you get roughly what it says in AH to use, unlike lead acid etc which is only 50% of quoted AH

In case this is of interest to anyone eles elooking at a pair of Lithium 12V 100ah batteries....

I emailed BATTERYMASTERS.CO.UK about their LiFePO4 batteries (they usually include a charger)..... Received this email offer.

If you buy model SLAUMXLI100-12C. These Can deliver 30Amps peek current.

If you buy the 2 batteries from us we can do

327.49 x 2 + vat

+ 40 charger incl. VAT (£825.98 Total INC VAT)

Sooooo...... Did anyone buy one?

I would think the carriage alone would be prohibitive.

Can they only deliver 30A, if so limited if any use with an inverter.

No address, no phone number, no company details at all.
30 day warranty, buyer pays return carriage.
Wouldn't touch them with a long stick.
