Custom NiMH Battery Packs Made
***Click on Thumbnail Images***
All packs use new Eneloop 2000mAh AA, Elite 1500mAh 2/3A, Elite 1700mAh AA, which I believe are the highest performing/quality cells I have found. I can use other other cells as requested, and have typical "D Cell" contact ends like shown in the images, except I'm mostly using white shrink now. Each battery pack includes one free pair of my red/black magnet charging leads as shown.
Packs are welded together with 5mil nickel contact strips,adequate for up to 30+ Amp sustained draw. Once assembled, each pack is discharged to 1.0 V per cell, then a slow (0.1C) conditioning charge is applied for 15 hrs. Pack is then rested, discharged and recharged until full at 0.6C. Eneloop packs are simply charged, as they do not need conditioning.
Payment will be requested by PM when pack is ready to ship, since I may need to obtain new cells. Please don't pre-pay. Just so it is no secret, I am generally trying to keep my labor and welder overhead charge to about $18-22 above my costs when I make these, and I am meticulous with details, so this is more of a fun service to the CPF community.
Despite my conditioning, bad cells can develop at any time, as such I will warranty these packs from defects or bad cells for 3 weeks after you receive them, so please test them out. You pay return shipping and receive new pack. This does not include not fitting in the wrong specified length mag, or one that is not adequately bored out.
Prices include $5 Shipping with U.S. Priority Mail in USA with Delivery Confirmation. (Deduct $2 shipping discount for each additional pack in same shipment).
PayPal only (Add 3% of total if PayPal credit card is used --Contact me if unable to use PayPal).
Shipping ouside of USA on case by case basis, the international shipping must be calculated by weight using the USPS.com website (online rates), but the best arrangement is the "$11.50 Priority Mail Flat Rate Envelope." No First Class Airmail shipments, sorry. Also , only Express Mail or Insured has tracking, so unless you choose those more expensive options, I will not be responsible for lost shipments. (I can say that to date, none of my shipments as been lost...although one sent to the Far East took 25 days)
Recommended Charger: There is a whole selection of affordable NiMH chargers listed here. The image above is of 9.8 to 18V (nominal) "Universal" charger which can be used up to a 15 cell pack. Here is another charger source if those are sold out.
Once you go to 15 cells, you then need a so called "Hobby" charger that can handle higher cell/volt/amp. I can recommend the Hyperion 1210i (from www.cheapbatterypacks.com) or Tritons which are listed here...but shop around. If you are going to get a new hobby charger, try to find one that does Lithium Ions & the new A123 Saphion LiFePO4 cells.

Elite 1500mAh 2/3A cells
AA cells for 2D or 3D can be made in tri or quad width stacks. Specify your need for a quote. Here are some prices with Elite 1700mAh & Eneloop AA's based on requests (includes $5 Priority Shipping to USA). Note: 3 wide fit stock Mag; but 4 wide need quad bore configuration (some 4 wide AA packs can fit in deep tri-bore)
Elite 1700 mAh AA cells
Eneloop 2000mAh AA
Charging Magnet Leads - (These use powerful Neodymium Magnets with red/black 16AWG carefully soldered so magnet remains intact.)
