UPDATE:
I went with a LiFePo4 for the safety aspect and ease of charging and discharging and storing. Decently priced at about $337 shipped. Came with SB50 Anderson poles which I use for discharging. Bought some APP45 for charging.
Made an adapter because the charger connector that comes with it is a household one which I don’t want hanging off my battery.
Built an adapter, household to APP45 until my real charger comes in that is APP45 natively.
Thanks for everyone’s feedback! Got her up and running.

It's been awhile since I've been on the forums here. Had a great time with several projects. I'm reviving a bike conversion from 2012 and could use some help with a recommendation for a battery.

It used to run on LiFePo4 that failed, but I'm looking at Lithium Ion as replacement mostly as a budget friendly alternative since Lead Acid batteries have doubled in price apparently. 12v 12ah batteries are $40 apiece and I'd need 4 for a 48v setup, so seriously looking at Li-Ion. I don't think I can afford another LiFePo4 at this time. I'm looking for something off the shelf that will fit in a battery bag on a rear mounted bike rack. 12"L x 6.75"W and 3.5"H
48v 20ah is what I'm going for. I have my eye on a $215 one from Amazon but looking for some recommendation for other sources for something safe with good longevity that I can depend on. I assume you guys aren't buying batteries from Amazon. Some home built or purchased from a pro here in the forums, but is there a website or other source that you guys are getting your batteries from? Not sure how prices have adjusted over the past 7 years, so let me know if that's junk and I should be looking elsewhere or if it's decent. My last LiFePo4 battery was 36v 10ah and cost $350. I remember cell_man used to be big here in the forums, but his website closed, so not sure if he's got a new domain or if he's no longer building batteries.
22amp controller is by Amped Bikes from way back, 36-48v capable.
Motor is 36v, but I plan to overvolt it to 48v since my controller can already handle it. I'm expecting the motor to possibly get hot, but I'll gear it accordingly.

TIA.
