You can purchase effortlessly online with Pirez, but also get the support with phone calls re what you are buying. Which is very helpful when buying technical items.
Best of both worlds. Modern shopping with the old school included.

Exactly what I ordered will do te job perfectly

It gives me around 60km range on a 500w motor on a 700c commuter bike, with some steep hills and probably 90% of the time on full throttle.
I discharged it to a point where it wasn't giving power to the motor, but the controller wasn't shutting off, not sure what it was, maybe BMS protection, I did a few cycles where power would come back and then go away again. After that, the battery indicator wouldn't even show charge (battery was turned on), so it was as empty as it gets.
After that, I was able to put 0.929 kWh from the socket into the charger it came with (after power factor applied), which has been certified to be at least 87% efficient. Which means the battery took at least 22.5Ah, which is 91% of the advertised nominal capacity. Which seems to be fine, I guess it's reasonable to expect lower usable capacity compared to nominal. Also charger might be more than 87% efficient, at 95% it would be exactly 24.5Ah, so it seems to be very close.
Will keep an eye on how this changes over time.
Overall very happy with purchase, but having USB would be great, and connector adaptor as well, was tricky to change bullet to anderson on my controller without anderson tools.

Good tyre easy to fit

Very happy with this battery and the prompt service from Pirez Electric Bikes.

The battery/rear rack package arrived promptly as per previous purchases from Pirez. The rack did need the front support rods shortened to fit my hybrid bike frame, but this might not be required on other frame types. The battery charge indicator Leds are a bit dim, but I tend to use the main bike display for battery status. The three red Leds, the taillight, are quite bright and have a flashing function if required. The battery needs to be locked in position while riding as it will slip rearwards otherwise. Compared to all my other E-Bike batteries it appears to be well made and hopefully lasts many years. Pirez has become my go to shop for all things E-Bike in recent years.

Ordered and delivered within days. Bonus, it’s also what was ordered. Exacting service.
