The Thunder Power 2-10 cell Smart Balancer will Auto balance (active if more than 0.005V imbalance) Lithium packs thus you may achieve higher currents and optimum charging conditions on all cells. This conditioner forces all cells which are part of a pack to hold the same current which translates into a high capacity pack. A balanced pack charges more quickly and most importantly will give you a longer flight time.

Digital Servo and Receiver Current Meter lets modelers check current flow between multiple linkages. It will monitor overall voltage between the battery and receiver charge current between the charger and charge jack or current draw when used between the receiver and servo. Modelers can even monitor discharge current between the charge jack and battery cycler. All voltage information is displayed on the easy-to-read digital display and can be switched between volts or amps. The unit comes wired with universal connectors allowing to be used with all popular systems.

The High precision voltage testing of transmitter and receiver battery packsand will also Test batteries under simulated servo load for accurate readings. The Meter is 4.8 or 9.6 volt for use with receiver or transmitter packs and other batteries which fall with in the range. Comes with a 2-year warranty.

This cool gadget displays voltage and charge level Discharge function has current load adjust from 1-3 (slow to fast) amps Red (danger) orange (caution) and blue (safe) zones on the circular graph clearly indicate voltage status Auto shut off and built-in fan Accepts Futaba J style input plug Uses receiver package voltage to operate Can be used with 4.8 6.0 and 7.2V packs (not with 8.4V or 9.6V TX) One year limited warranty. Use the BR-2000 battery checker in your workshop and at the flying field to check or discharge 4- 5- or 6-cell Ni-Cd and NiMH battery packs. It features a large easy-to-read LCD that has numeric and graphic (a gas tank) displays to show voltage. Housed in a sturdy plastic case that has retractable legs the easy-to-use unit has a start button on the front panel. On one side are the discharge-current adjustment dial (1 to 3 amps) the battery-voltage selector (4.8 6 or 7.2) and the battery connection port. An adjustment screwdriver and a battery connection lead with Futaba connectors are part of the package. To use the checker simply select the proper voltage connect the pack and press the start button. The voltage will be displayed (red background) for about 20 seconds. To switch to the discharge function hold the start button down for 3 seconds. The unit's internal cooling fan will start and the indicator will display the discharge voltage (blue background).

This EB 2001 Digital Battery tester is inexpensive and will give out and accurate reading of all DC batteries ranging from 4 volts to 13 volts DC. The checker comes with generic pin plugs so it is easy to hook onto wires or onto alligator clips. Very accurate with a large LCD display this battery checker will always keep you informed.
