What's the best Battery?

Look for a Li-Po, Lithium Polymer, those are the Best Batteries we have.

No Li-Po, then look for a Li-Ion Battery. Note, to charge Li-Ion or Li-Po, you will need a charger that will charge Li-Ion Batteries.

No Lithium, use a NIMH, No NIMH, use NiCD. Note: NiCd chargers will also charge NIMH.

At This Time, ALL of our Chargers charge NiCD, NIMH, Li-Ion, Li-Po unless otherwise noted.

At this time you can purchase on our Amazon Store, any radio battery, Radio Battery Charger & Radio Holsters and Leather. We are adding the links to the listings.

Of Course your Dept. PO is still welcome and we can bid you a qty of any battery or charger. Just E-mail me direct.
