Vision is 12 v 9 ah battery and other 12v 7 ah that's not fair compare 🙄

[Matadero]

The csb battery is 7ah not 9ah like the vision cp1290 tested in this video

I have 2 CP1270AC 12v Vision Batteries 7ah and 1 upstart 12v UBYTX5L-BS 4ah. How is the 4ah Upstart battery?

if charge is dropped in 12v its not working anymor? what if i just use 5v 2a from 12v 7ah battery with charge controller how long it will last ?

[RakshithPrakash]

I'm confused?!? So a battery advertised as 7ah, should supply 7amps continuously for 1 hour yeah?, But from your tests, it's supply 3 amps for around 30 minutes continuously before fully discharged so the actual capacity is 1.5Ah?!? I don't understand

[billieborys]

What did you use as a load for these tests? How big was the load?

[DavidJones-xvou]

The CSB should of been a 9ah and it would of been number 1

Your comparison is unfair. You are comparing batteries with different parameters:
Bulls Power is a standard 7Ah battery
GP1272 (CSB) is 7.2Ah
Datasafe 12HX35T is 8Ah
Vision CP1290 is 9Ah
No wonder that a 9Ah battery wins over all the others. :D
However the 0.2Ah difference between Bull Power and CSB resulting more than double time clearly shows that Bulls Power is of a bad quality product.

אחי האמפר שעה לא שווה. איך אתה עושה השוואה?

[freshmaker]
