These batteries have cells that are perfectly balanced but they need a BMS. We cut each lid open so you have easy access to the cells inside with the balance leads. The most common issue is the BMS bluetooth locked out the BMS on a lot of them. So all 4 cells will be well balanced and have good voltage. Just have to add a BMS. All of these batteries can be series connected into 24v, 36v, or 48v then you can just add 1 overall BMS.
These batteries were recovered from slightly used modules with laser welded connections. Only a few left at the moment.
At this price, if you are comfortable welding aluminum tabs or have a laser welder this is a great deal. We get asked about being able to tap and die into the studs and the answer is these cells have a tab that is roughly 10mm thick but of course you don’t want to go that deep if you do try that. We obviously can’t recommend doing this but if you want to give it a try at your own risk maybe limit the depth of your thread to 6mm or less.
This calculation also takes into consideration the maximum continuous amp ratings of the cells.
You will need M8 x 1.25 nuts for the cells. If you want to add balance leads to the small threaded insert you can use M3 x 0.50 short bolts maybe 1/4″ long would be ideal. Nuts and bolts are not included but they are very common. You can find them at most hardware stores, eBay, and Amazon.
These batteries are slightly used but guaranteed to cycle like normal. They are not capacity checked but we check each battery and make sure they are balanced, the light comes on, and the voltage is good. To turn on the battery just hold the button in for 3 seconds. They will charge and discharge like normal after you turn on the batteries.
These batteries were only used for about a year. They all have good voltage and a 15a rated BMS.
They are made up of 8x 3.2v 6000mah 32650 cells in 8s configuration.
The dimensions are 5 3/8″ x 4 3/8″ x 2 3/4″ and the weight is around 3 lbs.
These batteries have never been used, have a built-in 100a BMS, and came in the original pallet. They are all resting at nominal voltage. The brand names have all been removed so these batteries are unbranded but the batteries are unused and will work like new.
