youtu.be/bBTHPRCJUQQI didn't really like the options of batteries for the price of these scoots, so I gave this battery a try. Let me know what you think

This was all the rage in the early 2000's. When the 12v cordless drills came out. They didn't have a very high CCA, but if your kick starting anyway, it's fine. 👍

Consistent fast cranking and the electronics seem to be handing it very well. And a tiny bit of weight savings to boot 🤪

Have you had to charge the pack at all?

I was looking into doing that for my custom build a while back and still may, but I would not use the scooter charging system to charge the lithium battery pack. Beware there may be charging issues if you use the scooter charging system/regulator to charge it. The charge/discharge of lithium batteries is very picky. There is a circuit board on the lithium battery pack that controls charge/discharge. Looking at the pictures you can see multiple contacts on the battery, charger and tool. For the battery B+ and B- are marked on it and are the far left and far right contacts. The charger uses multiple contacts to charge and monitor the battery while it is charging. The monitoring of the battery pack during charging is necessary to prevent overheating and potentially a fire from occurring. You dont want a lithium battery fire under your seat while you are riding.

I was curious if you may know of a small control board or maybe even a stand alone regulator to control any current that may find its way to the battery installed. So far it's 450 miles with the battery installed and have had good luck, but would like to mitigate any issue in the future.

I was planning on running a ignition without a charging circuit and this makes me wonder if it’s viable option for lights? A dewalt 9 ah 20v will run a led 5000 lumen work light for 8 hours on medium setting.

Use a sealed lead acid (SLA) battery like from an emergency light or computer UPS unit. The scoot electrical system is all wrong for a cordless tool battery of any type.

ryan_ott uses SLA batts as mentioned above and I've rode with him at car shows for hours without him having trouble, though he has switched them out part way through at times since he carries a spare just to be safe. He'd had to give you the specifics, but his lights are low watt LED in the Zuma and he uses an electric water pump. This is with no charging, using a Malossi ignition. Charging anything if you go to racing setups seems to be tough anyway. My MVT doesn't seem to want to regulate. It will run 17V or so if I don't turn more lights on to tame it while cruising. I haven't tried a lot of regulators, but Yamaha and Chinese scoot regulators aren't doing it for me. From some reading and other comments here, high RPM setups sound like they're prone to these things. That may make even more argument for not even bothering with charging for high rev stuff if you just want to ride a couple of hours at a time.

As mentioned I’m using SLA 12V12ah battery. I modified the original battery box and fit this one in the same location. With the electric pump, leds all around and a few gauges I only have a 1.7a draw so I really should be fine going for 4 hours easily. Even when I change the battery out it’s always better then 50% charged.

Brooooo I would not do this unless you aren't running a charging system. Happypancake (I think) had a lithium ion and it caught fire, I would carry a fire extinguisher. Really, I would go back to a "normal" batt.
