I can only confirm the previous rating, these cells make for a great starter battery for motorbikes. Be aware however that the button top is not plus! I fried two BMS before I realized, and I have no idea what the manufacturers intention is here...
I recommend the "4S 12V Aktive Balancer BMS 30A 20A Instant 300A" you find on aliexpress (Posted on 20-06-23)
Kart/Paramotor starting motor battery Review by Kostas Hellas
Great battery for 35-40A starting motor for small 2-stroke engines. The battery is small, light and very well build.

I've used them in 1P4S and 2P4S (5Ah) setup, the results are very good as expected. BMS protection for over discharge should be considered mandatory! cheap moto batteries lack such protection.

Shipment may be longer that expected for low cost shipping option.

Good power Review by Ahto
Have build 2,5kwh battery for my electric kart from these.
in 34s10p format. 600A is no problem and will last 10 laps powering 50kw motor. Build thread: endless-sphere.com/forums/viewtopic.php?f=14&t=85912 (Posted on 02-12-20)
Very good battery Review by Ray
Gives a lot of current at the cost of lower capacity

LifePo4 has lower voltage than LiPo (different chemistry)

This battery is a serious current source. I have connected them 2p4s and they are able to turn my car's diesel engine (wires are getting very hot after such an experiment).

Love this battery (Posted on 30-11-20)
In a class of their own Review by Djordje Kg
Bought 50 pieces, receved MY 2018 which is good for me. Voltage equal all 2.889, exactly same. I put them as direct replacement for lead acid car battery. 5p4s, Current and capacity about the same as would be Pb 66Ah after a few cycles. Too bad they are less and less popular as time goes. Still - incredible cell (Posted on 26-11-20)

Powerhouse Review by atmosphere
The shell of this battery is the plus !
You get back lots of amps for the low capacity.
You can start a car with 4 of these in series .
Internal resistance is very low (Posted on 10-09-19)
Einfach Genial Review by Valera
Die Zellen haben alles nach der Einzelladung exakt die gleiche Spannung!
Beim meine gebautem Akku 4S2P Motorradbatterie habe ich mit 5 A Testentladung ca.5,2Ah entnehmen können.
Diese Zellen sind einfach klasse für die Starterbatterie bzw.andere Anwendungen mit hohen Strömen.
Die Qualität ist sehr gut was zu erwarten war von diesem Händler.
Hier werde ich wieder bestellen!
Vielen Dank Nkon!
The cells have exactly the same voltage after the single charge!
When my built-in battery 4S2P motorcycle battery, I have with 5 A test discharge can take about 5.2Ah.
These cells are simply great for the starter battery or other high current applications.
The quality is very good what to expect from this dealer.
Here I will order again!
Thank you Nkon! (Posted on 16-10-18)
