Specifically what I have is a an EM3EV triangle pack that I purchased back in probably mid-2016 if I had to guess. It actually doesn't have a lot of use on it despite being that old. In fact, the 2 1/2 years it's not been in use at all and all I have done is regularly put a charger on it at the 90% setting to make sure it stays in a healthy state of "storage charge." However, the issue is this - I don't have any "regular" bikes anymore. I ride a recumbent trike and without going through a LOT of trouble to fabricate a hard case and mount, I don't have any easy way to mount the battery to the trike. I can put a crappy case on top of the rear rack and stick the battery in there, but that's just a sorry-ass design, and not really that great for weight distribution, not to mention I use my trike to commute on and frequently carry a lot of groceries and I just don't want a bunch (15 pounds), of extra weight on the top of the rear rack.
The trike is a Sunseeker Eco-Tad SX, and Utah Trikes makes a pretty nice custom battery mount that will accept typical "shark" style batteries and mounts to the chainstays. I've been seriously considering just buying another EM3EV jumbo shark battery, as they're now cheaper than they were back when I bought this triangle pack (which is 52v 18Ah), and if it installs easily - well great! However, I have this other battery that has nice quality Samsung cells in it and ideally, if it's even worth it, I'd rather see if there is a way to send it somewhere and have the battery disassembled and maybe rebuilt into new configuration like another jumbo shark case. The other alternative is to sell it used locally in the Chicago/northern Illinois area, but again - a used battery without stats on number of charge cycles, etc. ? Do people even buy batteries like that? I mean it literally has probably been charged maybe less than 50 times since I bought it. It had the ability to give me as much as 100 miles of range which meant it would get charged maybe once a week.
It's just such an awkward form factor for anything other than stuffing in a padded bag in the main triangle of a regular bike. SO NOT EASY to figure out a way to mount it on the trike!
