I am building a 14s 5p (52v 17.5ah) Battery!. I am going to use a smart BMS, such as this one ( https://www.lithiumbatterypcb.com/product/13s-48v-li-ion-battery-pcb-board-54-6v-lithium-bms-with-60a-discharge-current-for-electric-motorcycle-and-e-scooter-protection-2-2-3-2-2-2-2-2/?attribute_specification-selection=14S+li-ion+58.8V+20A),. Do I still need a variable charger to Control the charging V and A? Any other suggestion with smart BMS/iOS compatible? Ta

Well spotted!!, peak is one of the reason I decided to build my own battery!. Had a communication with http://www.wooshbikes.co.uk/ but they don’t want to sale it with out battery, but they have answered my questions.

Haven’t used a bike for 25year and over55 year old, so fitness. Will Use the bike for commuting and shopping, trying not use the car. Some road are pretty steep in Sheffield, no idea about ascent in meter. My bike is not the right bike as I have to Mount the battery like a handlebar basket temporary to see if the idea does works for me, than I would buy a suitable bike. I think I have miscalculated the battery. How about this one (14S 5P 50V 17.5ah 3.3 kg) compare to your suggestion? Still overkill?

I have limited understanding when it comes to electronic and battery. Sheffield has hardly any flat roads, so I thought bigger battery is better. I haven’t thought about size, specially as I got down hill bike, which I was going to experiment on it.

Thanks. I am new to this world of forum and usually can’t find the answer for my questions. Advice goes a long way and you don’t get them in Alibaba!!.

Thanks for the link, I was trying to find a uk seller. Have looked at there prices and even though a bit more expensive than eBay I still rather buy it of smaller uk based company. Anyone has any experience dealing with this company? Any feedback will be great!!

My first ever Ebike and to save money I have decided to convert my Mountain bike. Your post has answered some of my questions, thanks for that. Someone has put a link of a uk seller and I am planning to buy a TSDZ2 of them. I am going to build my own battery pack with Samsung 25R. 14S 7P 57v 17.5ah. Is that combination any good?
