  • Best 72v battery ive bought
Color: 72V 20Ah

  • 72 volts is the way!
Color: 72V 20Ah
Great battery! Charges really fast with 4 amp charger included. Found out you can power a 1500 watt rear hub through an 80 amp sine wave programmable controller. I've had it up to 42 mph and climbing and if I could do wheelies it would! No problems.

  • Great fit.
Color: 72V 20Ah
I grabbed this for my cousin's mountain bike for his 42nd birthday as he is always hinting at having a second one. I Would I also feel more comfortable if he had a backup battery, since sometimes he gets pretty far up in the woods or out no man's land? With his adventures. He said this battery charges fast, it installed without any problems and fit almost exactly like his original one, and he couldn't tell any difference in the output of power even when going uphill. That is something a little bit over my head as it's not my thing, but I'm sure it makes sense to anyone that has a similar eBike lol. So good quality and price for what it delivers. ... show more
