Most of the e-bike batteries listed below use high-quality branded 18650 Lithium cells by Samsung, LG, Panasonic and Sanyo.  For more information check out my electric bike batteries explained article.

You will need to purchase the correct voltage battery for your motor kit and you will need to take into account the continuous current rating of your motor controller – for example, a Bafang BBSHD has a 48v 30A  controller, so you would want a 48-volt battery with a continuous current of 30A.

Another important consideration is the size of your frame. Smaller frames and full-suspension mountain bikes will have limited space for a typical Hailong case battery pack.

The batteries below have been selected to suit a variety of different electric bike conversion kits – please exercise caution when using a 52v battery with the Bafang BBS02 750w,  particularly if you are going to be using full power all the time. Tony has personally used a 52v battery on a BBS02-powered bike for 12 months without any issues, but I reprogrammed the controller and only used pedal assist. Check out my review of the BBS02 for more information.

The Bafang BBSHD seems fine with a 52v battery. The controller can comfortably handle higher voltage and current.
