DIY Battery pack

Hi,

I'm unable to afford a quality battery pack for my jvc gy hd111e.

I've read online about DIY battery packs. I'd like to ask, if anyone could advise me. As i'm struggling to understand volts etc.

If i use a 12v converter, and attach a 12 v battery to that. Could i use this to power my camcorder if I plug a power cable into the converter from my cam?

Re: DIY Battery pack

Some of those 12 volt to mains converters have a far from clean output, and I am not sure that I would want to plug your cameras PSU into one. It might be better to look at regulating the 12 volts down to the 7.2 volts that the camera uses, and use the DC lead.

Or five rechargeable cells in series would be about right. There might be reasons why that is not a good idea though, so hopefully someone with better information will join in. I would be inclined to forget about a cheap inverter though. Just my two cents worth...

Re: DIY Battery pack

Hi Andrew

Most electronic shops will have a little voltage regulator kit that is adjustable BUT it requires soldering plus you need a digital volt meter to adjust the output exactly!! I really wouldn't go that route unless you have the tools to do it ..I have made many camera packs that use a 12v CCTV battery and supply the camera with 7.2v but unless you have the skills don't go there!!

Surely you can buy generic batteries for the JVC ...generic (non genuine) batteries are cheap as chips on eBay so I think you would be better off getting a cheap generic if you need to save money.

Re: DIY Battery pack

I agree with Chris a generic compatible battery is probably the best way to go: Battery for BN-V428 BN-V408U JVC GR D93 GR DV1800 | eBay

UK sourced too so you will get a 12 month warranty with it and cheap as chips, you can also get car chargers.

Re: DIY Battery pack

It was not based on anything the OP said, but I had it in mind that he wanted long life from the camera without having to change batteries. For time lapse perhaps? Or similar application.

Re: DIY Battery pack

This is a dead simple regulator that is rock solid. I use them all the time and abuse the crap out of them.

Re: DIY Battery pack

Hi,

Yes, I'm needing something that can record for at least 50 mins. My battery's last at most, 20. I really can't afford an idx battery system at the moment.

Re: DIY Battery pack

Andrew...................

Can you just confirm some basics here?

I think your camera requires 7.2 volts DC - correct?

What current or wattage is required (Amps or Watts) to run the camera?

If this power to be originated from a cheap 12 volt DC battery or AC mains (household power)?

Armed with that information I can give you an idea of your best way forward.

Power consumption. 16.5 W
DC 7.2 V =2.3 A (VTR)
DC 7.2 V 1.2 (CHARGE)

12 volt.

Armed with that information I can give you an idea of your best way forward.

I've also looked at the stock li-lon battery. Is there any one that knows how to break these down to convert to battery pack/belt. I've loads of the batteries for the camera....as they only last 15 minutes. I'd happily convert them, if anyone can point me in the right direction.

Re: DIY Battery pack

Your best bet would be something like a 12v dryfit burglar alarm battery ( which can come in larger capacities - so will run longer , look for the amp-hours Ah rating ) . You could even get a leisure battery from the caravan dealer which would run your kit for days on end ( again like the burglar alarm batteries this is a lead-acid type battery but with the acid in a gel form so it does not spill - that would be a danger with car or motorcycle batteries - but bear in mind the likes of a 100Ah leisure battery will be the size and weight of the largest car battery , not exactly portable .

With any of the above you then need to regulate down to your 7.2 V - you will get a regulator from the likes of Maplin Electronics on your high street , CPC in Preston ( who are mail order ) or RS Components who are trade only but you might get access to them through work ?

Another option would be to look on eBay for a secondhand PAG belt which you would likely need to renew the cells in - tagged cells can be bought from the places I listed above and would need soldered in .
