Rayovac Pre-charged Rechargeable NiMH AA Batteries

I have been using these batteries for a while .I can defiantly say that these have saved me lots of money over disposable batteries  especially since these can be bought In a 8 pack for $13.97 at Walmart and come precharged. I try to always keep one fresh pack unopened and ready to go in case I forget to charge a set.

Recently I decided I would try a few other brands to see if there where any better deals out there but first I wanted to see what kind of capacity these batteries had to get a base line I used my GT Power X-Charger C6 to discharge the batties at 1 amp  down to 1 volt each and then recharged them at .5 amp and then a second discharge . The capacity that the charger reported with each group of batteries ranged from 650mah to 1450mah depending on there age . The oldest  group of 8 are about  2 years old and probably have over a hundred cycles through them with the newest having 2 cycles through them .

So far I have not had any complete failures but more than likely age will start to catch up with my oldest cells in the future.

• Recharge up to 500 times
• Reduce waste and save money. Keep disposable batteries out of the landfills and save hundreds of dollars when you use rechargeable batteries versus alkaline.

Protect your lipo's buy a lipo alarm

So you want to play with lipo's I highly recommend buying at least one lipo alarm .

I have found that a lot of cheaper brushless esc's have lower voltage cutoffs than I am uncomfortable with and this could cause damage to your new lipo .

They also allow you to use your lipo's with esc's that do not have a low voltage cutoff such as most brushed models .

They come in many varieties and from many sources .I find my self not recommending many of the high dollar brands due to them being the same as  the low dollar units found on Ebay , hobby king , and others.

So spend a little money and you may save a lot more money .

Cheap Lipo Sacks

Now it might seem silly but dozens if not hundreds of people have bought lipo bags or sacks that's are over priced. yes I know it feels good to spend a little more when it comes to safety but most of these sacks are being bought by companies and being resold under there brand for extreme amounts of profit . For example:

This sack being sold by Tower Hobbies for $15.99 under the Golden Horizon brand .

Versues this sack sold by Value Hobby for $5.99

Or this one Normally available for $5.75

Li-Po GUARD 25x33cm Safety Battery Charging/Storing Bag Protect your family and home from the hazard of lipo charging. This lipo-safe bag is a fireproof bag, designed to stop and contain the fire caused by incorrectly or poorly functioning lipos, especially during charging. We urge all customers to always practice extreme caution when charging and never leave a charging battery unattended. This pack is the jumbo size. It is 25x33cm/10x13 The Lipo-Safe Guard Bag is made from a fiberglass woven fabric. Similar to fireproof suits worn by some firefighters.

Hobby King even has a sack for $2.73

Now do I think all lipo sacks are the same NO the cheapest ones like from Hobby king tend to use cheaper thread to sew the sack up and to attach the Velcro and in some batched the fiberglass material will splinter more and make your hand itchy. Does this mean I don't recommend them NO buying any lipo sack is better than not having one . I have found the one's from ValueHobby and Nitro RCX to be of better quality and generally a better deal .
