|About li-ion battery|
This is a 72v battery designed for big power 72v -74v .Not only does the 72v battery give you more power it also
gives you more watt hours which means more range than a comparable amp hour 48 volt , 51.8v , 60v battery
this is a 72 volt battery so you are actually getting 1440 watt hours of power capacity.
battery pack builds its packs with the finest BMS (battery management system) available so that you can plug
in your battery and not worry about over charging. Your cells are automatically balanced by the internal BMS in the battery. Our BMS includes such features as temperature over heat protection and advanced cell balancing.
These features not only get the maximum performance out of your BMS they also keep your battery from getting to low,
charging too high, or getting too hot and will automatically shut off your pack if it senses something is wrong.
Cell Choice - Chinese cell 5000mAh
This cell is an excellent choice because its both capable of putting out good amps and power dense.
Our cells are guaranteed to be authentic.
Make sure your controller is capable of handling 72 volts. This battery is 20S which means when at full charge it is at 84volts.
we have 2A standard charger and 5A fast charger .
5A charger comes with a fan , it is Heat dissipation .
But if your capacity is within 15Ah , we suggest that choose 2A charger not 5A charger .
1. My battery pack stopped charging, what should I do?
A :Often if this happens it is due to the anti-spark feature built into the BMS. Say you did not properly make a
connection somewhere and the wires sparked, the BMS would shut itself down to prevent damage to the system.
If this happens the first thing you always want to do is to try resetting the BMS by using your charger to try
charging through the discharge connector for a few seconds, maybe a minute. You just run a jumper (basically regular
wires) from the charger's connector to the battery's discharge contact, making sure you go positive>positive
2. How do i know when it is fully charged?
A: If your battery has a voltage display on it then you can tell that is fully charged based on the voltage readout,
You can also test the voltage with a multimeter directly from the discharge connector.
3. My battery is reading volts, how much life is left before I need to recharge?
A: This is 72v nominal. this pack is full at 84v and empty at 55v .
For long battery life try to keep voltage at least between 84v -55v
4. Do you offer charger for battery?
A: Yes, we do.Our standard charger is 2A charger .If you need 5A fast charger ,please notified us .
5.what's your MOQ ?
6. can i get a free sample ?
A: sample is fine , free sample you are thinking to much .
