Another good battery no one has mention is the life po4 cells..
More then enough amps for ht and no memory effect .Also nimh are not as bad as nicd for memory effect ..an easy way around this is just about any rc charger "better ones" have a discharge feature to easily cycle your packs with .I'll. Cycle mine nimh 3 times before putting them to use .The controlled cycle is ideal for breaking these in.
I have had 4 lipo over the years go bad.
2 blew while in rc "bashing" and took out the rc.
The other two swelled while charging ."a sign to watch out for".
A quick Google search will show how dangerous these batteries can be.
The higher the discharge rate "normally 20c and up" the higher the risk .
As for cell phones and small helicopters the discharge rate is between 1-10 c so it's more stable.
All four packs I had that went bad were 120c + 10000mah packs.
If you do use these install lipo cutoff circuit before use "any rc hobby shop will have these or atleast should "
Nimh batteries of course are not all the same.i find high discharge rate cells have less tendency for memory effect then standard cells .These can be easily found at most online hobby shops or simply batteries is a favorite of mine.
The A size 5000mah 10 amp draw "I'm at the shop I don't have a part number in front of me" works extremely well for ht although since it's a A Size and not aa or aaa some case modification is needed .I use these for my ht and receiver packs on my nitro rc and I'm not the best of letting it fully discharge before topping it off .
When it comes to charging nimh cells a slow charge "I use .1 amp charge "100 milliamps" and gives you a longer run time..a fast charge will give you a slightly higher standing voltage on the cells "old rc racing trick" and also helps flash back a weak cell for a couple more cycles .
