Apologies for another recommendations thread but am looking for help given the current state of the market.
I am looking to build 2 packs into custom shapes to fit 2 bikes I am currently converting using TSDZ2's. My requirements are:
Motor: 48V, 750W TSDZ2 running OSF with SW102 and no throttle, temp mod
Battery: Aiming for 52V 14S4P for myself and possibly 52V 14S3P for my wife (but may also opt for the same 4P).
Use: Mainly cycle path and gentle off-road, we will be only running in pedal assist, no throttle fitted and not interested in long runs at top power. My use will be heavier than my wifes as hence opting for a bigger 4P pack as i will also be pulling the dog trailer but the intention is to help us get out more together and let me tackle hills which currently are very hard work with the trailer. Ultimate speed etc is not an issue, just making rides more comfortable and so we can cover further distance. This wont be my main MTB as I have my big FS bike for proper rides by myself or with friends, I will be interested to see how far i can push this off-road but this is not my main intention.
Current: I believe the controller is limited to 18A but I would be happy to limit that to 15a in the software if needed as that is still 750W at 52V or maybe even lower (10A) as we will still be pedaling and I am likely to be fitting 34T or 36T chainrings to reduce current load as top speed is not an issue.
Charging: I am intending to be quite strict on reducing overcharging and abuse, if that is a smart BMS or using a smart charger I am not sure yet.
i would like to maximise the available Wh if possible for the size and weight but the biggest problem I am having at the moment is cell availability. Ideally I would go LH MJ1 but just no stock, I am not limited to 18650 format so would consider others. UK sources ideal thanks to Brexit but importing just fine as long as a reputable supplier.
thanks!
