Hello! I inherited a recumbent bike recently and I bought this 750W motor and speed controller: https://www.ebay.com/itm/142505890334
I'm in the market for a battery pack now and I've compiled a list of parameters that are relevant to my search. I'd like your opinion on the list - am I missing or underestimating anything? Here's my list so far (I know a few of things are pretty obvious):
• Price - looking to minimize this as much as possible while maintaining quality :wink:
• Pack voltage - looking for a 36V pack per my motor/speed controller voltage
• Capacity - Would like a minimum of 12Ah for my commute
• Cell brand - probably will buy something with Sony/Samsung/LG or Panasonic cells
• Connector type - Not a stranger to soldering and crimping stuff so I'm optimistic I can accommodate any connector.
• Waterproof - I live in a pretty rainy city so waterproofing is a must for this build.
• Seller - Inexperienced in this field so I'm not sure which marketplaces or websites sell reliable/quality packs. I kept seeing the names Luna and em3ev so I checked them out. Luna does not carry a 36V pack and em3ev has a few but they seem a bit expensive compared to ebay/alibaba. https://em3ev.com/shop/em3ev-36v-10s4p-super-shark-ebike-battery/ Is this due to the quality/reliability of the cells?
Are there cheaper alternatives than em3ev and Luna that are still reliable? Anything else I should be considering in my list?
Thanks in advance!
