Thunder Power RC 205v & 210v LiPoly Balancer Tips & Tricks

The Thunder Power TP-210V and TP-205V lithium polymer battery balancers are plug-and-play simple and are a very powerful tool to maximizing the life of your lithium polymer batteries. Both TP balancers have various connectors for your battery, charger and data cables and sport LED status lights to let you know exactly what’s happening during the charge. Although these two TP balancers seem simple there are a few tricks to using them correctly.

When should you use a Thunder Power 205/210 balancer?
Balancing once every ten charges is useful, but we recommend using a balancer every at charge. Using a TP balancer every time you charge your lipolys is a very good idea because the battery balancer will provide early audio and visual warnings if any cells fail while charging. The balancer will also protect li polymer cells from going over 4.2V/cell during the charge thus extending the life of your lipoly battery packs. For greater safety and peace of mind while charging lipolys always use a Thunder Power balancer.

What do the LED lights on my Thunder Power balancer mean?
The TP balancer displays one LED light for each lipoly cell, and two status LEDs (one yellow, one red). The meaning of the LED lights depends on the situation. The first situation is when the battery is first connected, and the second situation is during a charge. Be sure to read the manual: TP-205v Manual | TP-210v Manual

• Yellow Status LED ON, red LEDs ON for 5 seconds = imbalance under 0.03V
• Yellow Status LED flashes, red LEDs ON for 5 seconds = average voltage under 3.6V (over-discharged)
• Yellow Status LED OFF, red LEDs flash for 5 seconds = imbalance between 0.03 and 0.2V (high imbalance, charge slowly)
• Yellow Status LED OFF, red LEDs flash for 60 seconds = imbalance over 0.2V (high imbalance, don’t charge until corrected)
• Indefinite danger beeps = Error: a cell is over 4.3V (stop charging, use caution)

Battery to Balancer Data Connection
Both the Thunder Power TP-210V and TP-205V balancers can communicate cell voltage information to Thunder Power chargers. This enables the charger to stop charging if imbalance becomes dangerous; a revolutionary safety feature. If you have a Thunder Power charger and balancer, we strongly recommend using them together with the data connection cable every time.

Temperature
These two balancers operate by converting energy stored in high voltage lipoly cells into heat and the heat warms up the balancer when it is active. Feeling your TP balancer’s temperature is a good way of determining how busy it has been recently, especially when balancing large li polymer battery packs.

Balancing 6 to 10 Cells
The Thunder Power 210V balancer can balance up to 10 series cells. Because Thunder Power balance connectors top out at 6 pins, it is necessary to use two connectors. You have two packs (or just one 6-10s pack), two balance connectors coming from those packs, and two connectors on the 210V – labeled Group A and Group B. The first step is to connect the two lithium polymer batteries in series. This is done by connecting pack A’s red power wire to pack B’s black power wire. Now connect pack A’s balance connector to the 210V’s Group A connector, then B’s balance connector to the Group B connector. Finally, press the Start button on the 210V balancer. You should see the correct number of cell LEDs light up.
