Recent reports indicate that rare instances of TETRIX Battery Pack burn-out have occurred in which battery packs overheated and produced smoke. In even fewer cases, the battery pack has omitted sparks.

It has been determined the largest contributing factor to battery pack burn-out is the puncturing or damage of the battery pack casing, typically caused by improper robot construction. Customers are encouraged to reference the TETRIX Getting Started guide for important safety guidelines and building best practices.

LEGO Education and Pitsco Education will continue to investigate this issue that has currently occurred in less than .2% of all battery packs shipped to date.

If you experience battery burn-out, unplug the battery immediately and contact LEGO Education Technical Support at 800-362-4308. Defective battery packs will be replaced free of charge and should be sent to LEGO Education for tracking purposes.

All LEGO® Education and Pitsco Education products are manufactured, packaged, and sold with the utmost regard for the safety of our users. We regret any inconvenience caused by this issue and welcome all comments and questions.

Care and Safety Tips:
The following are some basic battery pack care and safety tips that will help preserve the life of your battery pack.

-Never leave battery on charger unattended for extended periods of time.
-Pay close attention to not mount battery pack on robot where it may come into contact with sharp
edges or protruding screws.
-To increase battery life and performance, we recommend charging your TETRIX battery pack on the
slower charger setting of 0.9 amp.
