Amazing 1kWh Bulk Battery Pack deal! This listing is for 5x packs of 20-cell eScooter packs totaling a combined 1,000W with each individual pack containing x20 Eve ICR18650 or LGM26 cells in 10s2p configuration. Cells are coming in at around 90% of the original capacity. Can be used for building Powerwalls, for replacing Ninebot ES2/ES4 internal scooter battery, for powering e-Bikes, or for any other 36v devices requiring up to 5.2A per pack. For higher amp applications, combine multiple packs in parallel (combine using 3x Amp Booster or 12x Amp Booster). Combine in series to increase voltage as you need. There are bolt holes on the bottom that can be used to secure it and it also has easy access to the cells. These packs are “untested” and sold as-is.

Use as an Expansion Battery:

This battery pack can serve as an expansion battery for many popular power stations. It may be possible to connect multiple batteries in series to increase the charging speed (Volts), or connect multiple in parallel to increase capacity (AmpHours) and current (Amps), see your device specs for max limits. Plz double-check your power station’s PV/Solar input specifications to make sure this battery will be compatible. Use with:

• Adds up to 28% more battery to EcoFlow Delta Pro (Solar Charging Input 1600W Max, 11-150V, 15A Max). May require an XT90 adapter.
• Adds up to 33% more battery to Bluetti AC300 (Solar Input 2,400W Max., VOC 12-150VDC, 12A). May require an XT60 adapter.
• Adds up to 42% more battery to Bluetti EB240 (PV Max Input Power MAX 500W/10A, OCV 16V~68V /MAX10A). May require an XT60 adapter.
• Adds up to 50% more battery to EcoFlow Delta Max 2000 (Solar Charging Input 800W Max, 11-100V, 13A). May require an XT90 adapter.
• Adds up to 50% more battery to Bluetti AC200P (Solar Input 700W Max., VOC 35-150V, 12A). May require an XT60 adapter.
• Adds up to 49% more battery to Bluetti AC200 Max (Solar Input 900W Max., VOC 10-145VDC, 15A). May require an XT60 adapter.
• Adds up to 63% more battery to EcoFlow Delta Max 1600 (Solar Charging Input 800W Max, 11-100V, 13A). May require an XT90 adapter.
• Adds up to 114% more battery to EcoFlow Delta Mini (Solar Charge Input 300W 11–75V DC 10A max). May require an XT60 adapter.
• Similar spec portable power stations. You are responsible for double-checking to make sure this battery is compatible with your power station. When combining batteries, you are ultimately responsible for making sure your configuration (series or parallel) is compatible.

Most packs contain Blue EVE ICR18650 3.7v 2.55Ah cells. Some packs may contain another cell brand and color.

Charging

2A charger sold separately here. Can also be charged with a fast charger (needs an XT30 connector). Make sure you fully charge the pack as soon as you receive it and before using it.

 

WAKING THE BMS

Awakened battery packs have a blinking blue LED light on the top edge, near the XT30 connector. If your pack has no blinking light, it needs to be awakened. There are several ways to wake a BMS. The easiest way to wake this BMS is to fully charge the pack via the large discharge port, then apply voltage to the small JST PH 2.0mm 4-pin connector. The BMS LED light will turn from blinking slow red to blinking blue. See below for more instructions on waking up the pack’s BMS. Obviously, the packs will not wake without charge. Charge these packs using the NEW 42V 1.7A BATTERY CHARGER + MU CABLE BY XIAOMI or this variable charger. Make sure you fully charge the pack as soon as you receive it and before using it.

Battery Pack LED Indicator Lights

• Blinking blue = BMS awake
• Blinking red slowly = Battery charging
• Blinking red and blue = Battery trickle-charging
• No blinking light = Battery BMS asleep, needs waking
• Blinking red fast = Potential BMS or cell problem

Charger LED Indicator Lights

• Solid red = Charging
• Blinking red = Trickle charging
• Green = Fully charged / Not charging

When the charger is plugged into your battery pack you should see the charger’s LED indicator light turn solid red and the battery pack’s LED indicator light blinking red slowly. If you see the charger’s LED indicator light blinking red (trickle charging) and the battery pack’s LED indicator light blinking red & blue, leave your battery pack charging for an extended period of time until the charger’s LED indicator light turns solid red. Reminder, always monitor batteries when charging. See video below for additional steps.

Harvesting Cells

Scooter packs are great for harvesting 18650 cells as they typically have very low cycles.  To harvest the cells you have to crack packs open and extract the cells,  you’ll have to cut and clean the Nickel interconnects using snips.

Once the Cells are out and clean you will have to test them using a charger like this.

Typical Capacity: 2600mAh
Nominal Capcity: 2550mAh
Diameter: 18mm
Length: 65mm
Voltage nominal: 3.6V
Charge voltage cut-off: 4.2V
Discharging cut-off: 2.5V

 

This video shows you how to DIY harvest the cells, based on a very similar pack:

NEW YORK residents:
On 3/2/2023 New York passed a law banning the sale of lithium-ion batteries for mobility devices that are not certified to UL 2271, and the assembly and reconditioning with cells removed from used batteries for commercial sale within the state of New York (more details here). New York residents, you are solely responsible for researching, understanding and complying with all pertinent regulatory rules, laws, statutes, and NY safety standards.

Safety is important to us, we don’t want people to get hurt or property to get damaged, especially when working with DIY and/or second-life lithium-ion batteries. All batteries everywhere are inherently dangerous, so we urge all who work with DIY and/or second-life lithium-ion batteries to take safety seriously so as to avoid causing any harm to self, others or property.
