Default Most Durable Ni-MH?

Out of the current range of batteries which is the most durable cell, ie the cell you dont have to molly cuddle in order to keep the in good condition.

Looking to replace some old GP3300 packs that i use for club racing with something with a bit more go but i dont want the hassle of a strict maintenance routine like i have with my IB4200's. The GP's get charged, raced, discharged, eq'd then put in the box until next time, no storage charge no eq before charge, lovely hassle free. These are 4 cell packs so lip isnt an option

Ener-G cells have race proven results and also have proven to be a great choice. I have been beating my personal club packs to death and have had 0 failures. Thats even with out having to baby sit packs like we did some 3 months ago. So I would give 2 thumbs up to Ener-G cells.....

I'd go with Orion SHO if looking for a robust cells. I have some that have been seriously abused and still run fine.

Consider some Elite cells from Cheapbatterypacks. I've used them alongside some matched IB and EnerG packs and they are decent in comparison--a little less power, but very tolerant of neglect and less-than-perfect care. Though one pack, I swear, must have a 1 1/2 volt cell because it is a monster. Being unmatched, the opposite will occasionally occur, it must be said. Anyway, $50 for a 4700mah pack built up with 12ga wire and a Deans. Good price. And that's 6 cell for TC. 4 cells obviously less.

But where could still find sho4200 single cells?
Just because it's the best, then now is disappeared!

grepow/tenergy 4500s are good, although a little hard to find. i think there as another site like cheapbatterypacks.com that sold the tenergy ones. look for a pink label (grepow) or a blue one (tenergy).

i don't even use a discharge tray on my packs! (i know, bad idea, but i trickle charge most of the time so balancing isn't a problem).

Give the E-Power 4500 cells a try. They are durable, consistent and perform excellent charge after charge.

Thanks for the replies. I've heard good things about the Orions and i've have a pack of Greepow 4200's and i'm very impressed with them, esp for the price.

Out of the cells mentioned so far can any of them manage without a storage charge in between use, if so how long... days, weeks?

the 4500 grepows (same production run as the 4200 but a higher capacity) self discharge pretty quick. i let mine self discharge and cycle once a week or so.

For the price, you cannot go far wrong with any unmatched cell, whatever the brand if you are only club racing. You just need a good pair of hands and soldering skills

Got mine from rc-mart.

Good question. The battery debate lives on. I have 2 3300 GP Orion stick packs that I have just abused till there was no sign of life and they still hold a punch. Then I have 1 3300 matched AE Motorsports pack that is amazing, and 1 4200 Hurricaine matched pack. Out of all so far, the Hurricaine pack is SOLID. I'm a fan of GP cells. I heard that Energ are some amazing cells also, but its my opinion!

heres a little bit of what i've gone through.

3 different generations of IB4200s i've bought for my 12th, my ones which are only around 4 months old, one set 3 of the cells charge to 300mah the last cell to 4000mah.

I took them to 0.9volts per cell after each race, 3mv delta peak charge at 5amps, stored them with 3000mah charge....

My GP4300s, these were bad when i got them as they had been sitting around in the store for a while. the best these have charged to was 3700, they new peak at 3300.

Today having no good cells to race my 12th with this weekend, decided to bring out my GP3700s out of retirement (2 years since i've used them), they still all have 1volt per cell in them, I discharged them and charged them up, and they instantly had 4100-4300 charge each cell, with 95.5% match quality.

I never discharged my GP3700s / didn't do anything with them after my racing.

I'm thinking of buying some more GP3700s now

You got lucky on those GP's you just found again. If your not going to race for a while, fully charge them up and let them sit. We al know that Nimh loose juice if not used. You say that you charge at 5amp. Well, thats a good thing from what I hear. Thats why they lasted so long. I've got people that charge at 6amps and higher for packs that are rated for 5amps. I'm sold on that setting to charge at. You said also that you charge at 3mv delta peak. I haven't messed with that setting yet! I have mine at 0.1mv. Why at 3mv? I may be charging incorrectly...
