6s A123 packs for sale

[suicideneil]

I need to free up some cash so I am reluctantly letting go of my A123 packs I custom made a few years ago for my Emaxx.

These packs were built using genuine A123 26650 2300mah 30c/60c cells pulled from some Dewalt cordless drill battery packs, reconfigured by myself into 6s 'dynamite stick' packs which fit the Traxxas Emaxx 3908 perfectly, along with the GorillaMaxx chassis & the FLM chassis, just requires some velcro straps to secure them in place.

These are the packs recommended for the BL Emaxx by Castle Creations if you dont fancy using lipos; these packs DO NOT need an LVC ( Low Voltage Cutoff or Alarm ), you can literally run them until the power suddenly dies off at the end of the discharge.

These packs can also be recharged in as little as 15 minutes if you have a powerful enough charger ( ~10-15amps & ~200watts ), otherwise 2.3amps for a one hour charge roughly. These packs have balancer leads soldered up as it is still recommended to balance-charge them, connector is a standard JST-XH 6s plug. Voltage is 3.65v per cell fully charged, giving approx 21.9v for a 6s pack, equal to a 5s lipo.

For best results you MUST run 2 packs in parallel in order to feed the motor and esc enough current ( amps )- this does mean a small amount of rewiring but nothing too tricky & it doesn't have to be permanent ( you can buy or make the required parallel harness and jumper connector if you prefer ).

These are also great for e-bike builds.







The only bad point is that some dry grass has found it's way inside the packs as the clear heatshrink isn't sealed at either either fully & around where the balance connector exists the pack; you can easily extend or replace the balancer wires so that they exit the pack at the end and then seal the shrink with some extra tape etc. Some of the solder joints are a little ugly but they are all completely solid I can assure you, bare edges of the cells are insulated with tape where needed to avoid any shorts- care should be taken if you open up the shrink wrap to avoid shorting cells out on eachother ).

Otherwise the packs are in excellent condition, always balanced charged and stored properly- no more than a dozen or so runs on each pack so there is plenty of life left in them for a few hundred more cycles. Runtime of around 15-20 minutes is about average until the power drops off suddenly.

PM me for pricing or to make an offer, I can do a single pack, pairs or whatever- I am willing to sell these for fairly cheap as they aren't exactly brand new cells, but they haven't had much use either so will give you many more cycles before they start to loose capacity or punch.

Postage cost won't be too bad as each pack weighs 1lb / ~450grams, works out at £6/ $9 per pack ( 7-14 days airmail ), a signed for service costs an extra £5 / $7.50 on top of normal postage cost.

Brand new 6s packs sell for about $60 each, or ~$10-15 a cell.

Cheers guys.

PS: as with lipos sometimes, the resting voltage of a 'flat' A123 pack may be too low for the charger to detect the correct number of cells, in which case the best thing to do is charge the packs in nimh mode at ~1amp for 10-15 minutes, then re-start them in A123 mode ( 3.7v per cell maximum option, some chargers call them LiFePo4 or Li-ion, so choose the correct voltage option ) and see if the charger detects the correct number of cells with the balancer plugged back in, keep trying and after a couple attempts the resting voltage should be high enough- ~3.3v per cell seems to be the threshold for my charger.
