Yeah, you're all lame ass liars!

Your motor overheating you can solve somewhat by applying coolingfans to the motor hub (like computer heat sinks). You can also improve cooling by installing a more powerful motor. It seems like you're pushing the motor to the limit. If you avail too many amps from the battery to the motor, the...

Hey guys, Don't confuse the LiPo4 with LiFePo4! Xtreme is a cheaper company, they only keep the LiFePo4 batteries for their $3k+ bikes, not for the entry bikes. The differences are: LiPo4 has slightly greater capacity (you'll do a few miles per charge more). LiFePo4 has more recharge cycles...

'bout the same. 2 batteries in parallel only for longer travel distance. 'Peak' wattage is around 960W (not including wattage spikes)

Hi, I have the XTreme Xb-700li bike, and I tried to upgrade it by overvolting the bike, however the speed gains where marginal (about 1-2,5MPH for a 7,4V overvolt), and the regenerative braking did not work anymore. The bike uses a 700W motor, and a 48V 20A battery (which I paired with another...

Another correction on another user's post, and in correction of my own post concerning the 20Ah limitation on the controller, The battery of the XB-700 does not have a low voltage shut down, but when driving on a low battery, the controller tries to give the motor the juice it needs to drive...

There's no damage done, I'm currently doing this right now. The BMS will prevent one battery to charge the other until there's a 3V voltage difference, Just make 2 batteries, and connect them in parallel, no switch involved. It's perfectly safe, I'm currently running a setup like this for over...

LiFePo 48V goes for between $300 for 10ah, and $600 for 20Ah, depending on the capacity. Usually 20Ah is good for an ebike. What you say is true, shipping costs a lot, because the content (battery) is considered flammable.

You'll need a 700W minimum. Depending on the speed; if you want to go faster than 20MPH, it'd be better to double that watt rating.

I've seen 16x1" tires, but no 20x1. Best is a mountain bike tire?

Split up the battery into 2 separate modules. Connect them with 2 separate BMS'es. Otherwise try BMSbatteries.com.

Ok, there's a lot of bull out there on info on this bike; and a lot I had to wade through by experience. I want to post some of it here on this thread! First of all, the XB-700li has a LiMMn or LiPo4 battery. It's not the higher quality LiFePo4 battery. That means that the bike only has a good...

Is it a LiPo charger, or Lead-acid? Usually lipo chargers turn red (constant) while charging, and green when turned on. Blinking red may indicate a faulty battery, or dead due to low volt treshold LiPo's you can never run empty! If they have a BMS, the BMS will shut down the battery. Most...

Just ignore him. there are those that only can say negative things without saying anything useful. Regardless, I would not automatically assume that your controller is made for 60V. Overvolting is possible, reduces lifetime, but overvolting by over 50% is a risky thing to do!

Hi, For series connection, you don't need a BMS; although it's better to always have a BMS installed in the battery, for charging purposes. Just make sure your expansion battery (the one you're going to put in series with the main battery, is not too large (anywhere from 6-9V makes sense...
