Emag battery upping the amps

[shades]

Question: Do AAAs make up the cells of the Emag battery pack? If so can I use 750, 800 or 850mA NimH cells to make a more potent battery pack? and if i do will my charger handle it or will it be fine and just take longer to charge?
Problem: i recently took my emag down to fire test it but when it did manual mode worked fine, but e-mode would not trip the sear. Sooo... I removed the valve and held the sear down with my finger and felt that the selonoid was tripping with some gusto. so i replaced the valve and replaced my battery with the battery from my son's Emag and pow pow pow on e mode. so i have a need for a new pack but don't want spend $80 for a new one.
14- AAA 800mA NiMH battteries ,$28 @ Walmart
pack assemebly @ local hobby shop $15
grand total $43!
Err... about half price. and 150 more milliamps and more shots!

You can get 850mA NiMH but they were $32 for 16and they were a bit longer.

you take into consideration of frying the solenoid?

It should be no problem because would it is an increase in the amp/hr (Storage) of the battery not the voltage.

For Example: A watch battery is usually 1.5 volt, if I connect a AAAA, AAA, AA, C, D (all which are 1.5V) or any other 1.5 volt battery to a watch it will not fry the watch. But, since the watch requires so little current to work the battery would die from shelf life before the watch could ever drain it. plus who wants to wear a large heavy battery cell on their arm all day.

I spent almost 80 bucks for 8 AAA NiMH and a changer (the energizer ones) for a 12V setup for my warp.

Is Walmart selling no name bateries?

For the price I can get em I would go with the AGD bat anyway.

The batteries I got are on sale. Rayovac IC3-15minute 800mAh 4 pack for $7. I bought 4 PACKS for $29 with tax. That 150 mAh more storage than a stock pack from AGD. I just want to Know IF these are the right size, and if they will work with my charger for the Emag.

Put 14 AAA NiMh in series and they will work just fine.

Thanks for the reply, Would you know if AAA cell are the correct size or if the ones in the original pack are an odd size(like AAA 7/8) and if my charger can charge the greater amp/hr safely with out damage?

This is a follow up. I ended up taking my AAA cells I bought at Walmart to a hobby shop. there they built the pack for $10. My Grand total was $38 for a new 750amp/hr 16.8v pack plus two extra cells on in which I used in my old pack to fix it.

Well hows it operate. Give us details. Does it last longer? Is it about the same weight?

It is about the same weight. I dont have a scale. But no noticable difference. The big change is the balls per charge you will get for the same size battery pack. AGD 650mAh(miliamp/hour)-Mine 750mAh!
I could made one that was 800mAh but the 750mAh were on sale 4 for $7 at WalMart.

You could use bigger cells like AA, N, C, and D but you would have to wrap the pack around the tank or some how.(you still would need 14 cells) Plus it would be MUCH HeavIer. And take longer to charge. With C or D cells you might only have to charge them once a season while running your marker, warp and revy/halo.(and a scooter, just kidding )
Found some NiMH D cells that have 10,000 mAh storage! That is well over ten times the storage but probably at ten times the weight and cost.
AA 2500mAh are $10 for 4 this route make more sense. That is $40 for 16 cells (use 14 with two extra) and small size and almost quadruple the storage. and not too much more weight.

Hey there shades,

I was just wondering. How has your home built battery pack been holding up? Have you had any problems? Are you using the original EMag charger unit or something else?

Thanks for any info. My battery died and I wanna see if I can make one myself.

Thanks

Docrocker - i can't speak for him but what he did should work perfectly.


One caveat, i would go with nicer brand name cells for your battery. You get what you pay for with batteries, usually.

Hey Snniper1rfa,

Thanks for the advice. So what are good brand batteries? What is a good price for them?
Can I still use the stock charger?

Thanks

Hey,

How did you pakc the batteries? I mean, 14 AAAs together are a larger volume than the stock battery housing, right? How did you connected it to your marker? Where did you placed it? Could you send me some pics? My e-mail is [email protected].

Thanks!

[sniper1rfa]

nope, the stock battery IS 14 AAA's. Thats why its so huge.

Good brands for rechargeable are sanyo and gold peak. Make sure that is gold peak OEM cells, not the crappy consumables of the same name. They come in yellow shrinkwrap with goldpeak written on them.

i'd stick with duracell/energizer/sanyo for consumable rechargeables (the ones with a nub on the positive side, rather than no nub.)

They look like they sell up to 900 mAh consumer type cells, and up to 800 mAh OEM cells. I know nothing of the seller, my old source of batteries disappeared and i havent needed any since. The little picture looks like gold peak.


Don't buy anything from powerstream. They are ********.
