Lithium-Ion Batteries -3 out Charger - Expansion Board and Programming Card  - Wolverine Battery share double  switch and Sahara  adjustable Regulator   shown below - Call  Store  $

 

We have used the canister Lithium Batteries for almost 15 years now. These batteries are only new to those who haven't tried them. Almost all competitors and TOC flyers have used them since the mid -late 90's. They are well proven and have many advantages. Light weight, no cycling, fast charge, highest power density battery of any battery on the market and no memory problems. Cheaper than nicads, it is only a matter of time before you will be flying them in your plane.  Radio manufactures have already started the process of switching to Lithium.

Fires?  If these batteries are used properly with common sense and  the correct chargers - well lets put it this way - How many cell phones, lap top computers, digital cameras, Dremmel Lithium ion powered tools, Digital camcorders etc? have you heard of blowing up? 

Most of the safety issues have been due to modelers hooking up incompatible chargers to battery configurations that aren't compatible with the charger. 

Dumb chargers hooked to dumb batteries are a sure way of starting fires. That's a modeler issue not a battery issue. 

Poly packs for electrics are packaged differently and have their own unique handling characteristics.  We don't use them in our giant scale aircraft.

Call us if you would like to switch to Lithium - Ion . We can help you save pounds instead of ounces by switching to Lithium.  These batteries are cheaper than nicads. Call for current pricing. Available Store Direct

Our book Gas Engines Giant Planes has a chapter devoted to Lithium Ion batteries used in giant scale aircraft.  Available Store Direct

Regulators  By Jaiccio

 

Jom Odinno - former 35 year columnist for RCM and the O of S&O Proportional radios,  developed   this regulator years   ago  for high performance  IMAC-Giant Scale and Pattern  planes.  It  weighs about 1/2 oz, is set  to either 6 volts  or  5.1  volts. and is  used  on our  42% planes .   Input  voltage  up to 15V  and output current  up  to 5  ams.  ( A  42% plane   with 13  digital  servos   wil draw  about  2.8 amps average if the plane  is set up correctly. )

Large Fromeco adjustable regulators shown above or fixed voltage regulators shown below are available to fit the needs of various size aircraft.  Call us and we can help you select the appropriate regulators for your planes.

Available Call Store Direct.

Would you take a $1000.00 stereo, DVD Hi definition TV with surround sound and hook it up to 220 Volts?  Of course not - You'd toast it - Then why would you run your $1000.00 radio, servos and accessories, that are designed to operate up to 6V, and overdrive it with 7-8.4 volts - and then wonder  why the system acts funny, or not at all, or won't range check or etc. etc. etc. 

Some radios and servos won't  work at all with unregulated voltage, some work intermittently and some will tolerate the voltage overdirve but its not recommended by the manufacturer.  JR voids your servo warrantee  if  you operate  non hi-voltage  rated  servos  at more  than 6V. 

6volt nicads actually charge up to about 7-7 1/2 volts and lithiums batteries charge to over 8 volts.  Use a regulator  to regulate the voltage down to 6volts.
