EMP triangle Battery pack will give you the ultimate in long range at an affordable price and is designed to fit in a triangle bag inside the frame which is the ultimate mounting solution for a conversion ebike. In America there are many motors that are super [owerfull its about time someone made a battery to handle It as it will put out as much power as almost any ebike controller will output. If your ebike is not that powerful dont worry, the battery will only dish out as much power as the controller asks for and no more so you wont fry your current system. This pack comes with a very advanced BMS (battery management system) which protects the pack from damage during charge and discharge.
This BMS also has temperature protection to keep the pack from getting too hot during discharge and charging.It is a high power BMS which will allow the pack to put out 50amps continuous (2500 watts) and 80 amp bursts (4000 watts) although running this much power will reduce packs life expectancy so we recommend to not run your battery to hard if you expect it to last over 500 charges.
Don’t forget to buy a charger we recommend buying a charger that is below .5c for the battery so if your battery is a 20amps we recommend using a charger that is at least half that amount. 20/2 = 10 amp charger
We build our batteries in America because we understand that the motors here for ebike are very powerful. So if you plan to buy a motor in America that is more than 500W you should consider buying a battery that can handle that power. In china most motors are 500w and below so the batteries they build in bulk are normally for 500w motors . This is why we encourage everyone to make sure you have a strong battery to handle the motors, even if you don’t by the battery from EMP make sure you are informed!
