eMotive Propulsion

Thundersky LFP series of batteries are the #1 lithium battery imported into North America. The solid-state lithium iron phosphate chemistry provides both a light-weight and stable source of power that doesn't have the thermal runaway issues that earlier battery chemistries did. Coupled with the proper battery management system the LFP's can last in excess of 5,000+ cycles. They are more stable and safer than Lithium Polymer and have far higher power to weight ratios than Lead Acid, Gel Cell, NiMh or NiCad.
Lithium Ions are the future of electric vehicles and we use them exclusively. The additional cost more than pays for itself in space, weight, power and longevity.

We stock a large number of 40ah and 90ah cells since they are very commonly ordered. However we are constantly placing new stock orders for our own warehouse. Unlike other companies that make you wait up to 6 weeks for delivery, if we don't have enough cells for your order, shipments take approximately 2-3 weeks to arrive at your location, depending on the date of order. They will be shipped directly to you, any other product you ordered from us will ship immediately and separately and you will be notified at the time of order of any delays. Feel free to email us to check on current stock numbers of cells. All in house cells are checked and inspected prior to shipping to ensure you receive matched cells and all are adequately charged for shipping. Thundersky batteries include a 1 Year warranty against manufacturing defects.

A Battery Management System is required for all Lithium Ion cells. We have the best price on the most affordable and reliable BMS systems we've tried. The Elithion BMS system is easy to install and easy to use. Click here to order.

We also custom fabricate aluminum battery boxes to any dimension or size and can preinstall your batteries and BMS if you like as well. This way you receive a plug and play Lithium Ion power source that's ready to use right out of the box.

Feel free to contact us with any questions that you may have.
