Just got an email back from one of them companies on the alibaba site, for a 12v 20AH samsung battery pack, with overcharge protection, 1000 cycles per battery life, and a few other features. They are

Isn't a milli amp 1000th of an amp; so 18,000 milli amp/hr should be the same as 18 amp/hr, I think !! LOL !!   Cheers.

Unlikely to get a refund from Deben,but your thinking on the right track,it shouldnt be difficult with a little savvy to offer these batteries at a much cheaper rate,the big firms always make cash on

in fact mate...if you dont want it..i will pay you the postage to send it to me...and i will take it around to my mate who loves an electrical challenge..i bet he can make one for a quarter of the price of debens once he sees how it works and gets the part numbers and a board diagram.

Getting back to the original post - First of all that's a HUGE cell for that sort of money!! In fact, I'd be highly inclined to point a few of my motorbike racing pals in it's direction as that would be absolutely ideal for a total loss setup.

 

Beyond that though, that pack has a few obvious pro's and con's:

 

Firstly, the charger must be built into the pack - you can't have a cell stack that size and not use a balance charger, it'll just kill itself in jig time and usually with spectacular results - so there's no way in hell that little wall adapter is the actual charger (and if it is, then AVOID LIKE THE PLAGUE!!). Operating on this assumption then, the pro is that you don't have to buy an Li charger for it.

 

The flip side of that is that you've no idea of the quality of the charger installed - and for Li to work properly, they genuinely do need a very well regulated charge.

 

The other con is that it doesn't list the discharge rating of the pack, so it's impossible to know how suitable it is for the type of draw that you would have off a halogen lamp. Personally, I couldn't see this cell having any hassle providing a sustained 5-6Amps, however, without a stated discharge rating there's no way of knowing for sure.

 

Hope this helps.

The cell on the original link may not be the most suitable for the use we are looking for but there are plenty of alternatives on the alibaba site, with alot more information on discharge rates etc ;)

You would need some sort of foam to pack around the cell to stop it rattleing around inside the box but although its heath robinson it would definately do the job. ;)
