This is the ProTek R/C "Supreme Power" 4S - 14.8V, 3500mAh, 100C Lithium Polymer hard case battery pack. This is the ultimate battery for qualifying and shorter mains in 1/8 scale e-buggy applications when you are trying to reduce running weight! This battery is 135 grams lighter than the ProTek 4300mAh 4S battery, and 316 grams lighter than the ProTek 6700mAh 4S pack, making this is an awesome option if you are trying to put your 1/8 e-buggy on a diet. These battery packs are built using a hard plastic pack that is required for use at ROAR sanctioned tracks and events.
This pack includes an integrated balance charge lead with a Deans style T-plug installed for a convenient connection capable of handling extremely high amp rates. While the 5-pin Align/E-Flite style XH connector provides compatibility with one of the most common varieties of balance tap connection.
These battery packs are built using a hard plastic case that is required for use at ROAR sanctioned tracks and events. The packs are designed specifically for those 1/8th scale electric racers who don't mind sacrificing a little run time for the increased performance of a lighter car. At about half the weight of our 6400mAh 4S packs these packs go a long way in weight reduction and still give you the 70c punch your looking for.
Unlike most other Lithium Polymer batteries, these batteries can be charged at up to 2 times the rated current, or 2C! If your charger is capable, you can charge these batteries at 7A!

1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery

6) YOU MUST not over discharge the Li-Poly battery pack
7) READ & UNDERSTAND the instructions carefully before operating this battery
NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in over heated batteries. Discharging capacity can't exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for first 5 cycles. Always monitor race time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell). Do not use the battery that has too low a voltage.
Do not expose batteries to sunshine or store/charge batteries at the temperature above 35°C or in a closed car. The high temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging or racing, do not charge the battery until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.
