Do you guys realize that you can buy a 36v40ah thundersky lifepo4 at evcomponents.com for the same price as a 36v20ah ping battery? Just saying. All I seem to hear about is ping this and ping that. We should support the businesses who are going to make lifepo4 cheaper.
36v40ah thundersky from evcomponents.com = $530 after shipping about $600
36v20ah from pingbattery.com = $470 + $150 to ship from China = $620
