These packs are built with a lexan plastic shell around the outside of the battery, and then covered in blue heat shrink. The lexan shell is designed to protect the battery cells while in the vehicle, for longer life. Note that due to the lexan shell, sometimes the battery may feel soft to the touch on the outside of the battery; this is normal as there is a small air gap between the lexan shell and the battery cells inside.
Why must Li-Poly receiver packs be used with a voltage regulator?
Although the Li-Poly battery pack’s nominal voltage is 7.4V, when it is fully charged the voltage output is 8.4V. The 8.4V output exceeds the safety level of most receivers and servos on the market, so if you are not using High Voltage servos, you must use a voltage regulator with these Li-Poly receiver packs to decrease the voltage to safe levels that your receiver and servos can accept.

1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery
4) ALWAYS use a LiPo charging bag
5) YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
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.

Performance was excellent. My ProTek 170SBL steering servo was extra responsive on the high voltage. Run times were top-notch -- no surprise since normally these only power servos & receiver. But I run strong servos, a MyLaps transponder, plus a LapMonitor transponder, all at the same time, all the time, and my throttle servo is fighting a rubber band failsafe so that's gotta be a slightly higher power draw than the average nitro buggy.
In August 2021, a friend wanted to try out nitro buggy but needed some help, so I gave him one of my batteries since I figured I didn't really need 2 of them. The battery I kept went from 59 mOhms when new, down to 56 mOhms after 1 year, then crept up to 63 mOhms earlier this month (May 2022). Unfortunately, last weekend it spiked to 296 mOhms at the same time that cell #1 went to zero voltage. I know they don't last forever but being a premium make/model, I purchased it expecting to make it to the 4/5 year mark, or at the very least 3, but this one made it just past 2 even though I'm diligent about storage charging (to the point that I datalog resistance/voltage readings).
