    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.

    • Losi Micro-B 1/24

    Nathaniel Collins Verified Owner Monday, Mar 24 2025 (6 months ago) ProTek RC 2S 30C HV Hardcase LiPo Battery for Losi® Micro-B (7.6V/420mAh) Great little batteries. You have to remove the stock battery tray to get them to fit, 4 screws on the bottom, easy job. You can use some of the foam from the packaging for a tighter fit if you don’t already have some. Same “C” rating as the stock batteries but the extra capacity will give you a longer run time. It being a bigger battery and removing the tray, you can get some more weight lower allowing for some more fine tuning of the car. I will definitely be picking up some more of these for my Micro-B fleet. 3 customers found this review helpful. CLA Monday, Jun 16 2025 (3 months ago) ProTek RC 2S 30C HV Hardcase LiPo Battery for Losi® Micro-B (7.6V/420mAh) This is a good idea for a battery on the micro b since the stock spektrum battery that comes with it is junk, so you can charge it without having to use the Spektrum charger that comes with it, but way over priced like most other Protek batteries. 0 of 2 customers found this review helpful.
