Hi,
I have been researching and reading the forums for a couple of weeks, and am about to take the first plunge into the exciting world of Electric Bikes!
I have got an old steel framed mountain bike sitting in the shed, that is asking for an electric conversion!
My use case is for riding in the UK on gravel tracks at weekends, probably using pedal assist more than throttle, so may not be hammering the battery too hard (not too concerned by the legality of throttle/wattage- as long as I don't ride like an idiot then no-one will know or care plus some use may be on private land).
For my first attempt, I have decided to go for a 1000w 48v ebay special with LCD display from here.
I am considering going for 52v 20ah battery made up from a 6s, and 2x4s from HK listed as "Multistar High Capacity 5200mAh 4S 10C Multi-Rotor Lipo Pack" here and "Multistar High Capacity 10000mAh 6S 10C Multi-Rotor Lipo Pack XT90" here. Is this a suitable setup or have I made any glaring errors?
I understand that I need to carefully select a decent LiPo balancing charger and power supply.
Can anyone point me in the right direction as to a decent balancing charger, that doesn't cost the earth or would it be cheaper and less hassle to bulk charge with a cheaper charger and then check with a standalone balancer periodically (every 10 cycles maybe) without a nice warm LiPo fire?
Also I have been reading about BMS. Is BMS necessary with this setup? How is it used? Does it strap to the battery group, for both charge and discharge whilst riding? is it one per block or cells (4s or 6s) or 1 for the entire block in series (14s)?
Thanks in advance for any help that you can give me! And I hope I have got the terminology correct as it is quite a steep learning curve!
Kind regards
