ProTek RC 4S LiPo 20C Battery Pack (14.8V/2100mAh) (Starter Box) w/T-Style Connector
About this part
This is the ProTek R/C 4S 2100mAh, 20C Lithium Polymer battery pack. This pack has T-Style Ultra connectors pre-installed, and comes with a 5-pin Align/E-Flite style balance connector.
This battery will also make an excellent starter box battery for R/C Cars! You can significantly reduce the weight of your starter box, as one of these batteries will weigh less than one third of two 3600mAH NiMH packs (221g vs 802g). This will make your starter box almost 1.3 pounds lighter! Not to mention they will have increased voltage and punch, making it easier to start a tight engine.
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 4.2A!

IMPORTANT:
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.

I have been using this in my Ofna truggy starter box for a year now and has been flawless, A+ lipo!
Great Lipo. Money well spent. Powers Truggy box easily. Protek=GOOD!!!!
This battery is perfect. I was a little hesitant at first because of the small size. I was going to be using this to break in a new Orion engine which are known to be pretty tight, and was worried about running out of juice. Happy to say it passed with flying colors and then some! I have never even came close to running this thing down, even after a full day of starting issues and multiple uses. The small size of the battery combined with the ultra light low profile Hudy Star Box, makes for one of, if not the lightest setups out there!
Perfect battery for my mugen starter box. Works awesome 6 months in. Worth the money.
Last a long time and has plenty of power in my Ofna Truggy Start starter box
Reviewers overwhelmingly rate this 4S 2100mAh starter box LiPo highly, most giving five stars. They commonly praise its strong power for starting new engines, long run time over full track days, compact and light size, and reliable charging. Several owners say it has lasted months or years. Reviews are about the Starter Box variant. Two reviews report failures: one 1-star review describes dead cells roughly seven months after purchase despite careful storage charging, with high resistance readings; one 3-star review reports the pack puffed about six months after a storage discharge. These are the only negative experiences, and the reviews do not establish how common such failures are.
- + Strong power for starting engines
- + Long run time over full track days
- + Compact and lightweight
- + Charges reliably and balances well
- − Dead cells reported after about seven months
- − Pack puffed after storage discharge
- − Limited number of long-term failure reports
