* When installing the battery it’s very important to not let it bounce around at all and to put padding anywhere the battery comes into contact with metal. [Closed cell foam type padding](https://www.amazon.com/Artilife-Neoprene-Perfect-Cosplay-Padding/dp/B08FX3V8Z7/ref=sr_1_7?keywords=closed+cell+foam&qid=1645587858&sprefix=closed+cell+%2Caps%2C266&sr=8-7) that bounces back after compression is needed. You probably got some in the shipping box that your battery came with. * When installing the battery it’s very important to not let it bounce around at all and to put padding anywhere the battery comes into contact with metal.

* Check the plug for corrosion. If there’s a lot of carbon buildup a.k.a. black stuff you may need to replace the plug. The plug should be shiny and golden colored. Don’t just use a plug with a bunch of black stuff on it it’s going to melt away in no time. Check both discharge and charge ports. * Check the plug for corrosion.

* If storing for the winter, discharge battery to between 50-70% charge. This will help keep the cells in balance. Try to keep the batteries inside and not let them get too hot or cold. They like to be above freezing and below 40c. They also don’t like to be in a damp musky basement. If storing unused for more than a couple of weeks it’s a good idea to unplug them from the ev. Use a multimeter to make sure the battery doesn’t have a slow drain. If so your battery may have an issue and you should proceed with caution. Batteries should be able to go 6 months or more without a significant drop in voltage while being stored. * If storing for the winter, discharge battery to between 50-70% charge.

## eBay
* I tried to find a cheap 30ah 48v battery on eBay, what a shit show. These eBay sellers are getting really bad. Don’t be fooled by the huge ah rating. There’s no possible way to cram that much capacity in a 3p battery. The cells would need to be 10,000 mah each. No 18650 can even come close to that and I highly doubt they are using larger cells. I am sure the other specs are inflated as well like amp rating. If you exceed the amp rating on the battery you may cause cells to pop and cause the whole pack to go up in flames during a full throttle pull, especially with a low quality BMS. I messaged one of the sellers(screenshots below) to try and get the cell they are using so I could calculate the ah rating myself and they tried really hard to scam me. Please be careful on eBay. It may be an ok cheap battery when low amps are drawn but the specs are 100% fake.
