Emmo Knight Turbo upgrades

this may be a little redundant but im still not grasping the math here im terrible at it i found these guys here im think 2-3 maybe 4 would suffice?

or six of these green ones

this is such a serious find though man, thank you but im in canada

dang ill screen shot

OR

I would not do six of those green ones.
Each 12v BMS needs to be able to handle the full pack voltage when connecting them in series ~72v. It's likely those 12v green batteries are max safe series connection (x2) 24v, maybe (x4) 48v.

theres a pic that shows at least 20x of them connected together, its way more than six but there is another one that does show what your saying 2-4x of them connected. can i link you?

i was doing some digging and found this setup config for these batteries


**Connecting the Packs in Parallel**:
- **Positive terminal** of Pack 1 (Battery 1) connected to **positive terminal** of Pack 2 (Battery 3) and **positive terminal** of Pack 3 (Battery 5).
- **Negative terminal** of Pack 1 (Battery 2) connected to **negative terminal** of Pack 2 (Battery 4) and **negative terminal** of Pack 3 (Battery 6).

**Resulting Output**:
- **Voltage**: **72V** (12V × 6).
- **Capacity**: **70.2Ah** (23.4Ah × 3).



now to get that out practically to fit in the bike would be the challenge

Did you get that out of an LLM? I strongly suggest not using AI if you can't evaluate its responses yourself, especially in a topic as sensitive and dangerous as batteries.

If you can't plan a pack yourself, your best option would be to order a ready-made pack to fit your vehicle. There's plenty of companies around, I know a lot of people used Amorge but you might want to look around locally.

yeah it was a last resort though thats acucally how the SLA's are set up in my bike right now

also thank you for the site suggestion i was so discouraged when i read the setup i was going for had to be reconfigured

its 16x accually, but i figure 2s3p or 3p2s COULD work but im getting mixed messaged everywhere, ill drop the link anyway incase you wanna lurk or head over

im just looking for the most affordable and fastest shipping, which is these, but this is my first bike and upgrade, im handy and patient when i comes to install but gathering the parts is what kills me, you gotta kindof do it first try and make sure it sticks,

Maximum those can handle is 4S, so ~48v. Hooking up more in series presents imminent risk of permanent damage to the batteries, or worse and likely, a fire.

Though it's common to hook >4S with SLA chemistry, I don't know of any off the shelf 12v Lithium batteries that allow series connection greater than 4s, due to the max ratings of components in their individual BMSs.

This makes sense though would 4 be fine for the bike with a different controller? Like say a 48v controller and the batteries Cuase they could potentially, well they’re definately better than the SLA batteries I have in it now

would this battery be better
