ProTek RC Losi Mini T/B & JRX2 Performance Battery Upgrade

The ProTek R/C 2S 50C 1100mAh Losi Mini T/B and JRX2 LiPo Battery is built with performance in mind. Using Silicon Graphene technology this battery packs a punch with it’s 50c discharge rating! Designed to work with the Losi Mini T, B and Mini JRX2 this pack offers extended runtimes with it’s larger 1100mah capacity. Equipped with an EC2 style connector makes this a plug in option with no need to mess with adapters or to get out the soldering iron. With more time on the track and the ability to dish out the power this Protek battery pack is an excellent upgrade for your Mini T, B or JRX2 vehicles.

Lab testing has shown that ProTek R/C Silicon Graphene packs have double the cycle life when charged at 1C rates, and can be charged at higher amp rates, with less risk of damage to the pack. More importantly, the discharge curve is flatter, meaning the cells maintain higher voltage throughout the discharge cycle with no significant drop off. Additionally, when compared to conventional LiPo batteries, Silicon Graphene batteries are lighter, providing a higher capacity per gram ratio. With 7.4V nominal voltage, high discharge ratings, incredibly high charge rates and a variety of models to choose from, ProTek R/C Graphene packs are perfect for racers and bashers that demand the absolute best.

Note:When purchasing this battery as an upgrade for the Losi Mini-B it is also required to buy a standard 2S LiPo capable charger.

Features:

• Direct fit for Losi Mini B, T and JRX2 vehicles
• More runtime, with a dramatic increase in punch
• Silicone Graphene can handle more abuse and deliver more current than a standard LiPo battery
• Improved efficiency, lower operating temperatures, and lower internal resistance!
• Factory installed EC2 plug

IMPORTANT LITHIUM POLYMER SAFETY INFORMATION

• DO NOT leave a battery in your model when charging
• DO NOT leave lithium batteries unattended when charging
• ALWAYS balance charge lithium battery
• ALWAYS use a LiPo Safe charging bag/box
• YOU MUST use a Li-Poly specific charger to charge lithium batteries (NiMH or NiCD only chargers WILL NOT WORK!)
• YOU MUST not over discharge lithium battery packs
• 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 overheated 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 the 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 a battery that has too low a voltage. Do not expose batteries to sunshine or store/charge batteries at temperatures 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 it until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.

• (1) ProTek R/C Battery

Valued Customer Verified Owner Thursday, Aug 31 2023 (about 2 years ago) ProTek RC 2S 50C 1100mAh Losi Mini T/B & JRX2 LiPo Battery w/EC2 Connector Just ran first run on my son and I’s Mini T 2.0’s with the ProTek packs. MAN WHAT A DIFFERENCE! vs a stock dynamite Reaction 2 battery pack. ProTeks were barely warm with 20% charge left after running in grass, light gravel, and multiple high speed passes. Upgraded ESC and Motor were slightly warmer to touch.
