Hello all,
I finally decided to start the process of building an e-bike; it's been something I've considered for a long time. I decided to go the folding bike route as I live in a small NYC apartment and I really can't have two full-size bikes. I decided on the BBS02 for the motor and now I am onto the battery and this is proving to be a bigger hassle than I thought. I posted originally on Reddit but didn't get much response, though, it did help to push me away from the cheaper options I was looking at originally.
Here are the options I widdled down to:
UPP 48V 17.5Ah Hailong-3 Samsung 35E $375 840wh
UPP 52V 17.5Ah New Hailong Samsung 35E $399 910wh
EM3ev 48V (13S4P) 13.6ah Super Shark $379 653wh
BMW 52V **8ah** Samsung 40T $310 416wh
I'm leaning most towards the 52v from UPP; I reached out to see if I would be able to get the Bluetooth BMS version after reading something on this forum about some of their packs not balancing when charging and I'm waiting to hear back. I'm really looking to get input on my picks and maybe options I don't have that you may think are better. I really have base-level knowledge of this stuff, there's no way I could go the self-built route and $400 is really the max budget for the battery.
Also, what would be a good charger to get? Additionally, I want to keep this as safe as possible, do you have any other charging safety tips? Charging/leaving this battery out of my apartment isn't a possibility. I've read a bit about and even saw it mentioned in the BMS link, using ammo boxes for charging as one thing.
About the bikes use:
Commuting during good weather and general rides around the city. I'm a photographer, so my commute isn't a set distance/frequency. Regardless, I don't see most days going over the 20-mile distance.
Thank you for reading and any input you can pass my way.
