The L3 52v 20.3Ah from Electro Bike World has a 80amp burst and is very powerful! It has genuine Panasonic cells with high quality BMS that comes with a 1 year warranty. It has an epoxy plastic surrounding and protecting the cells and are professionally wrap with shrink tubes that are made from a reputable battery company. Also included in the price is a 4amp high quality aluminum case charger with built in fan and free shipping to the lower 48 states. I don't know any place that gives you this kind of deal for the price. Many people are using this battery and not a single user has any complaint but all have given great remarks and satisfaction.

Don't try to knock something down if you have never used it just to promote your homemade battery which is obviously what you're doing. If anyone wants to trust someone to build your battery from scrap parts out of his garage then by all means....to each their own.
