Wisper 905 battery replacement(behind seat post model)

Featured Replies

I have an old(2008ish) 905SE which has given me great service over the years. It has been stood for a while and I'm passing it onto a friend as a intro to ebikes but the range is now quite poor(understandably). What are my options for replacement. I had a quick look on the Wisper site but couldn't see them.

Give David @Wisper a call as he can recell/provide a replacement or send it to Jimmy @BGA for recelling with better quality cells ne will reuse the existing BMS and price is a lot cheaper then anew complete battery.

 

No doubt David will reply to you on this thread as he keeps an eye on anything that is his brand and is always keen to help out with all models.
