Wiring mechbox in parallel
 

Is it possible to wire 2 batteries in parallel to the mechbox to have more amps at once? I'm planning on doing that to my kraken, having a battery in the stock and one in the upper receiver.

I'm also planning on replacing the original bolt for the ICS bolt and bolt carrier, but I read in some threads that you can't use a stick battery with it. Can someone help me clarify these issues?

with a ics bolt you can not use a stick battery

Yes it's possible to wire in parallel.

It is but I don't recommend it. There's a lot of issues such as charging and uneven discharge. If you want to charge them, it'd be best to disconnect them and charge them each fully individually. There's also more potential for shorts. There's just too many cons for just extra battery life. Swapping batteries isn't that hard.

Why do you need more amps? That won't increase your ROF (as voltage won't change). It would allow you to pull a heavier spring but I'm assuming your Kraken already pulls the spring you have.

The receiver only holds a mini stick. So if you want to run two packs in parallel, it'd mean using a mini in the stock as well, instead of the usual large.

It'd make a lot more sense just to use a large pack in the stock, or move to LiPo all together.

Heck, what sort of performance improvement are you trying to achieve with this?

Yea, I was hoping that more amperage would give increased run time because I used to do the same with small Lipo packs in my RC days.

You're not going to have any run time issues using a good large sized NiMH or NiCd pack. They'll run for many thousands rounds, we're talking several bags worth of BBs. Parallel wiring is completely unnecessary.

I'm not sure if a large type battery would fit in the stock though. I tried fitting my 6 cell RC packs in there and it barely fit, so i don't really wanna commit to buy a $40 battery and have it not fitting.

Well, it is a Kraken. I guess it might not be the same as a proper TM. However, even a mini can run all day, provided you're sensible on the trigger.

rc packs are probably bigger than airsofts battery. i have a large battery on my kraken and it fits w/ no problem

By large batteries, do you mean the 4200 intellects? Or somewhere around 3600, 2400 or something like that?

If you do, you'll want blocking diodes on each + so your batteries dont discharge into the weaker cell.

Any of those are the typical large batteries used in airsoft.

So how large of a battery would it take to last an entire game day firing in short bursts?

I have a Tenergy 8.4v large 2300mAh and charged it full and it last 2 weeks in 2 outdoor games. And I'm not a spray'er.. I take time so I probably shot 1000 rounds in those 2 days in 2 weeks, and the battery still lasted.

A large or mini would do fine. It's better to have 2 mini's and swap them when 1 battery runs out of charge.
