Smart Battery

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.

FAQ:

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 

and negative>negative.

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?
