The Speed-T is equipped with the Xcelorin Brushless System combined with the Losi EC3 connector. It has been designed to provide
the maximum current flow to the Xcelorin Brushless System.
It is recommended that you use the Losi EC3 connectors on all your battery packs to ensure efficient power delivery to the Xcelorin
Brushless System. The connector is gold plated and is able to handle the high current loads of the Speed-T.
Overview of Battery Packs for Use
All of the Losi recommended batteries, 6-cell or 7-cell side-by-side, and both 2-cell and 3-cell LiPo battery packs come equipped with
the Losi EC3 connector.
Only use NiMH or LiPo type batteries. The selected NiMH batteries should be capable of high discharge rates with low internal
resistance and should be assembled properly to maintain a high rate of current flow. There are many options to choose from but an
investment in a quality battery pack will benefit you, the user, in the enjoyment of your new Speed-T. The less expensive batteries will
generally lose their performance after continuous use in this high drain application.
We do not recommend the use of batteries referred to as Stick Packs, they are commonly constructed with thin metal battery
connectors and may result in personal injury or fire.
Things to look for in a good quality battery pack are:
• Battery connections
o High current connector in between the cells, not a thin metal tab.
• Wire leads from the battery.
o Wire should be 12 or 13 gauge providing high current flow.
• Connector used to connect to the Speed-T.
o Many battery packs will come with high resistance connectors that will restrict the current flow resulting
in poor performance.
o It is recommended that these be changed to Losi EC3 connectors.
Also ensure there are no exposed wires that may lead to shorting of the positive and negative power leads. A short can cause severe
heat and result in personal injury and damage to the battery pack, radio equipment and the Xcelorin ESC. Use good heat-shrink tubing
as required to ensure there are no exposed areas that may result in a short.
