Bit tetchy there Mark. They work fine on my Eclairs...NPR and ACL.

I recommend glueing velcro all over it so that you can attach it very easily to the camera, to your belt, etc. It may be a good idea to add a extra layer or two of heat shrink plastic on it before applying velcro so that the surface is more sturdy.
You can even buy a cheap basic clip on utility belt from local hardware store and use it as a "battery belt", just attach the battery with velcro and you're ready to go

LiPo also work on mine but they have no strength to go up to 50 or 75fps. That's why we discussed that NiMhs at 13.6V and 5Ah in order for my motor to pull that speed.

Just to let you know that the above battery works perfectly at any speed on my Acl II with heavy duty motor. Not very small but light and beautiful made.

I am also interested in building/ buying a good battery solution for the Eclair ACL II and it is quite urgent since I want to film end of march.
I have never built a battery so it would be great to get some advice. Attached is an image of some parts I would think could work but as I said I have no clue. Ideally I want it to be onboard (with velcro) and easily swappable just in case they do not last very long or charging takes ages.
Will 10x AA 1,2V batteries each 600mAh do? I am just planning to hook that to a spiralcable and a female xlr 4pin microphone plug...
just wondering if that would work at all and how long would it power the camera? and what about recharging?
Or does anyone have a list of good parts that are available on ebay/ online?

hi, which model exactly do you use? Is 3,5Ah enough for higher framerates? I've heard 4-6Ah would be ideal? Can there be too much?

I didn't know anyone actually sold NiCd anymore. They're markedly inferior to NiMh.
Anyway you couldn't expect to draw 4-5A from an AA. The voltage drop would be very high. You need larger cells, Cs or Ds at the very least.

Good to know thx, I though if I have like 10 of them it will ad up to the amount I need.
Regarding the NiCd´s; the cinematographer I bought my camera from told me NiCd would be better. Don´t know why.. but one thing I read was that with NiCd it does not matter when you dont use them for a long time, there is no danger of loosing capacity or anything. There is still lots of them around and they are still used in Hospitals and elsewhere probably due to that reliablity
hm difficult decision, the "tracer" option seems easy but may be a bit expensive. Building it from scratch will be risky though, having no real experience and all that...
if I`d go with the "tracer" can anyone recommend a specific model of battery from them?

so you would just velcro that pvc wrapped pack on your camera and somehow connect an xlr cable?
Posted 20 February 2018 - 04:29 PM
I use a Canon DSLR [NP-E3] 12 volt battery with my ACL, which is attached to the camera with a velcro.
Posted 20 February 2018 - 05:20 PM
I saw that before but thats a pretty expensive battery unless you own them anyways and where did you attach the cable and how do you charge it and do you get framerates above 25 with that?
Posted 21 February 2018 - 04:03 AM
I don't think they are expensive just checked and they are about £25 from Ebay, I bought two and you can also get chargers for them too. You can get 25fps with them, they last a long time, plus they are very light.

sounds good, what kind of cable did you make/use and how/where did you attach it?
Posted 21 February 2018 - 07:36 AM
It's the XLR cable, the ends are just taped to the neg and positive poles of the battery.
Posted 21 February 2018 - 11:03 AM
so there is an opening in the battery on that side? -- do you have a close up of the construction by any chance?
