Tenergy 4.8V 2000mAh NiMH Receiver RX Battery with Hitec connectors for RC Cars and Airplanes

This was a much more affordable way for me to get a new battery for my Spektrum DX7S transmitter instead of buying a Spektrum branded battery pack for twice what I paid for this. I did need to cut the connector off of the old battery pack - being careful to only cut one wire at a time to avoid shorting out - and to cut off the connector from the new battery pack - again being careful to only cut one wire at a time. A little soldering and a couple of pieces of heat shrink and I was back in business. The battery pack is an exact fit replacement for the original Spektrum battery.

The back up battery for my home alarm system died again. The old AA 4pack of NiCd cells had been replaced once already and they simply wouldn't hold a charge anymore. The physical dimensions of the 4.8V Tenergy battery pack was identical but the wire connector was different from the one on the alarm system. I clipped the wire leads on the new battery pack and soldered on the old ones, put it back into the alarm system and it's been working fine ever since. The alarm company said the old battery packs were no longer available and that I'd need to upgrade the system for about $700.00. The 4.8V Tenergy battery pack replacement was a much better solution. Thanks!

As per price it is OK.

Excellent. I use this for my BBQ grill built in LED lights instead of replacing AA batteries all the time.

I had to cut the plugs off the tank's original 400mAh batteries and solder those plugs onto these 2000mAh babies. Do you think the kid I bought them for will like that?! I use a 4.8V Tenergy Smart Charger (also sold at Amazon) to prevent overcharging and insure longer battery life. Both work well. The effort I had to put into making these tanks play longer was well worth it. The original Chinese junk would only play ten minutes before they needed to be recharged. These will now play just over an hour without any memory related problems.
