This ProTek R/C 1S 3000mAh LiPo transmitter pack was developed specifically for the Airtronics/Sanwa M17 and  MT-44 transmitters. This light weight LiPo battery will help to reduce the overall weight of your transmitter, which is great for long main events! The overall weight will be significantly reduced when compared to a typical NiMH transmitter pack and will provide an incredible amount of run time!


How should the battery be inserted into the transmitter?
A suitable foam should be used to pad the battery in the transmitter battery compartment to help hold the battery in place and prevent it from moving around. Place a piece similar in size to the battery into the transmitter battery housing under the battery, and then while pressing lightly on the battery, slide the cover over the battery.

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 35C 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.

Great battery pack. Perfect fit. And the light weight of it makes the MT-44 even more balanced.

ProTek RC 1S LiPo Transmitter Battery (3.7V/3000mAh) (Sanwa M17 and MT-44)
After buying the MT 44 Transmitter and not being happy with the battery run time of the pack supplied I picked up this one.
I am very happy with the pack and the run times between charges.

Keep in mind this is a 1S cell pack and not all chargers will work with it.

ProTek RC 1S LiPo Transmitter Battery (3.7V/3000mAh) (Sanwa M17 and MT-44)
I wish I had another set of hands to give this battery 4 thumbs up! Nice to have my radio light, and with over double the capacity of the pack that Sanwa makes, I sometimes go 2 months without having to charge this pack, and I practice at least once a week (sometimes twice) and race once a week! Great job protek! Im proud to represent a company that makes such fine quality products!

ProTek RC 1S LiPo Transmitter Battery (3.7V/3000mAh) (Sanwa M17 and MT-44)
Quality TX pack. switched from the old school dry alkaline batteries to this pack. keeps the lightweight feel of my mt44s but gives me days longer battery life. fits absolutely perfect in my mt44s.
