Project: Battery pack

I recently rediscovered my air rifle and as such have been thinking about how to improve it. I have already made one small addition to keep a small amount of ammunition handy whenever I grab the gun.

When I first bought the gun I also went out and bought a cheap gunlight to use for lamping/ratting at night (I bought a second hand version of this). This search should yield something useful. the particular torch I bought came with a normal torch cap and a momentary remote switch. which was great because I could use it as a nnormal torch when i wasnt out hunting. the only proble is is that it only takes two CR123A batteries which are extremely expensive considering that they only last about 6 hours before the light starts to fade and flicker.

So I hit ebay for a quick shopping spree and after some searching and comparing (every little helps 😉 ) I found these battery holders to be the best value for money. Although you could try this search instead: battery holders.

Because rechargeable AA batteries only put out 1.2 v instead of 1.5 I will have to conduct some prelimiary test on the birghtness of the torch runnign at 4.8v (4×1.2). the chances are that it will work just not be as bright(single battery holders are on the way as I write and I will test at a full 6v too).

The plan is to connect a 4 cell holder and a 1 cell in series, and then test the duration, then as necessary add more of these combos in parallel, until a sensible amount of battery life is reached or the pack gets too heavy.

I you’re interested this is where I get my pellets from as my gun is very fussy about which pellets I force down it…:

The ebay store where I get my pellets from although at the time of posting they seam to be all out. (they shipped 2000 RWS superdomes for around £30 which I thought was pretty good value for money)
