Modular Robotics Recalls Rechargeable Battery Packs Due to Burn Hazard
Consumers should immediately stop using the rechargeable battery packs, contact Modular Robotics for a free replacement battery pack, and then safely dispose of the defective product by following local laws for disposal of the batteries.
The Dexter Industries Rechargeable Battery Packs are being recalled due to the fact that they can short circuit, causing them to overheat, posing a burn hazard to consumers. About 2,400 units were sold between March 2018 and January 2020. The majority of units were sold directly from www.dexterindustries.com. They were sold individually, and also within GoPiGo and BrickPi Classroom Kits.
The Dexter Industries Rechargeable Battery Pack is a 9.6 200Ah NiMH battery pack with Max Charge Current 2A and is wrapped in black plastic. “Dexter Industries Rechargeable Battery Pack” is printed on a white label on the battery pack.
Modular Robotics has received four reports of the rechargeable battery packs smoking and overheating. No injuries have been reported.

What product is affected by the recall?
The Dexter Industries Rechargeable Battery Pack is roughly the size of 8 AA batteries wrapped together in a black plastic wrapping. It has a white label on one side that identifies it as a Rechargeable Battery Pack. Here is an image of the Rechargeable Battery Pack:
How can I tell if my Dexter Industries Rechargeable Battery Pack is at high risk of overheating?
Look at the red and black wires where they attach to the battery pack itself. If they are visibly frayed or the red and black wrappers are broken, then your Rechargeable Battery Pack has a higher risk of overheating. Please take it to a professional battery disposal facility as soon as possible to mitigate any risk of overheating.
If your wires are not visibly frayed or do not show other signs of heavy use, your Rechargeable Battery Pack is not in the high risk category. Please still take it to a professional battery disposal facility as soon as possible. They may offer to repair it for you. We will not cover the costs associated with refurbishment, but will reimburse costs of disposal with a receipt (most companies will dispose of your Rechargeable Battery Pack for free).
Where can I take my Dexter Industries Rechargeable Battery Pack for safe disposal?
Check out this link and make sure you have selected Nickel-metal Hydride Batteries.
Google “Battery Recycling Facilities near me” and take your pick! If you have concerns about whether someone will accept your battery pack, call ahead. They are more than happy to answer all your questions (we tried calling a few places and they were all very helpful – and free!). Other good news: Battery Recycling Facilities are considered Essential Services so they are open even in regions with stay-at-home orders.
Can I get reimbursed for costs associated with safely disposing of my Dexter Industries Rechargeable Battery Pack?
Yes. If you paid a small fee for disposal of your Rechargeable Battery Pack, reply to the confirmation email with a receipt along with your proof of purchase. The service should be completely free if you are disposing of only one or two battery packs and will only be ~$5USD if you are disposing of more than that.
What can I do with my robots without a Rechargeable Battery Pack?
Both the BrickPi and GoPiGo robots are compatible with normal AA batteries (we recommend rechargeable AAs, but standard batteries will work, too). Your robots would have arrived with a Battery Holder like this one:
How is the replacement Rechargeable Battery Pack better than the product I am disposing of?
The replacement Rechargeable Battery Packs have two main safety features that the original battery packs did not have. First, they are equipped with physical strain relief in how they are wrapped. This protects the wires from fraying near where they attach to the battery cells, thereby preventing the most likely cause of an electrical short circuit. They also include a PTC fuse (Positive Thermal Coefficient) that limits the electrical current when a certain temperature is reached. This prevents the battery pack from causing fire or other damage. You may notice one small part of your replacement Rechargeable Battery Pack getting warmer than the rest of the pack – that is the PTC fuse doing its job, protecting you.
When will the replacement Rechargeable Battery Packs be shipped?
We currently expect to ship replacement Rechargeable Battery Packs in June, but will update this section of the site as soon as we have more details from our manufacturer.
