hi,
This is my first post so I hope you'll go easy on me (not sure what kind of forum this is yet).
I spent a couple of hours researching this but came up empty so:
I am looking at a used 36V ebike battery pack for some projects (e.g. a hoverboard hack) but it has no charger.
The battery is this "California" "Advanced Electronics Energy Limited" "AEPCM100136V10AH000360" 36V:

I found two chargers that seem to match in terms of voltage and the type of socket (I'm not sure if the socket is an exact match though):
"36V Charger 42V 2A electric bike lithium battery charger for 36V lithium battery pack with 3-Pin XLR Socket/connector"
~ $17 https://www.aliexpress.com/item/4000864496646.html
"XINMORE Charger 42V 5A Scooter Lithium Li-ion Battery Charger Bike AC-DC 36V 5A for Switch Bicycle Electric Tool XLB Plug"
~$30 https://www.aliexpress.com/item/32864407989.html
(I guess the used "California" battery pack I'm looking at is more likely XLR and not GX16-3 due to it not having a groove for the GX16 dimple)
1. Can anyone tell me if I will be able to charge that battery safely and without damaging it with both of those chargers listed above? (not sure which I'll get yet but I'd rather spend $17 than $30, although the faster 5A charge rate is attractive on the $30 one)
Does it matter which charger I get in terms of potentially damaging the battery pack? I watched an interesting video about charging lithium batteries and it mentioned that charging at too low a rate can massively reduce the number of charge cycles/lifetime for certain chemistries (https://youtu.be/pxP0Cu00sZs?t=1487) or if the charger has slightly too high upper cutoff voltage (https://www.youtube.com/watch?v=pxP0Cu00sZs&t=2151s), although maybe that's controlled by the battery pack internal BMS? I don't know.
2. Does anybody know what kind of socket that is on the battery pack output? Is it a standard or some impossible-to-find proprietary thing? Or what kind of hack/spade connector/etc. I could force into it to get power out (choosing a connector and cabling appropriately rated for the expected current)? Or maybe I should open up the pack and put in some other connector of my choice (if so, which one?))
