February 10, 201511 yr Hi Chris You need these and DIY skill plastic chopping board copper plate Anderson connector 16awg wire Sugru I will try to take a photo of the connection later
February 11, 201511 yr Ok, I think I'm stupid. Is the clear plastic what you call "chopping board"? How do you find a piece that fits the battery? Does it somehow snap on to the battery or do you have to tie something around it not to fall off?
February 11, 201511 yr Sorry to mislead you. I use a piece of plastic I found from the garage. If you can find a plastic chopping board and cut the shape you want. Once it is in I use a Velcro strap to hold them in place. I put them in the pannier bag and I have no disconnection issue.

For the chopping board adaptor, look at craiggor's pics in this thread (posts 69 and 70) I suspect even then that something may be being tied around it though. I'm going that route and going to try making the mount shape using a router ( might require lamination though).
February 11, 201511 yr The groove is 5 mm.the first chopping board I bought was.8mm,I used 4 layers. And finished the top with some 3 mm. The first layer is the hardest it needs a groove cutting in it.if you get it right no rubber bands needed.if you had a router no problem.but I cut mine with a hacksaw.i have made 2.one i got one side of one slightly wrong and i can lift one side just a bit.
February 25, 201511 yr Would anyone know if it is posable to charge two of these in parallel.with one charger ?
April 30, 201511 yr Would anyone know if it is posable to charge two of these in parallel.with one charger ? I dont see why not. The charger seems to be simply a power supply, the charging circuitry is integrated inside the battery so connecting them in parallel would simply mean slower charging.

May 1, 201511 yr It'll charge them in parallel, but what happens is that one battery will charge the other through the output wires, so you bypass the charging safety controls. If one battery had a duff cell or went out of balance, you could get a fire. I doubt that it would do any harm for the odd charge in parallel like that, but if you want to leave them in parallel all the time you should put blocking diodes on the output leads of each pack.

August 31, 201510 yr If anyone is interested I have four of these battery packs for sale... bought them for an e-bike conversion project that never happened. I'd just like to recoup my investment so £34 a piece? Collect from Cambridge or I can try and find a courier to ship them at cost (suggestions welcome)
August 31, 201510 yr I'll ask the woman at work that I did her Brompton for. I used two of these batteries so I'll ask if she wants any spares.
September 1, 201510 yr I'll ask the woman at work that I did her Brompton for. I used two of these batteries so I'll ask if she wants any spares. Do you have any info on how you did the Brompton conversion with these batteries? Curious.

Please let me know if you can sell them to me Thanks Pat
September 1, 201510 yr I built some battery mounts like previously in this thread and used them on a "nano" brompton kit. both batteries fit in the handlebar bag quite nice.
December 16, 20169 yr Hi hope someone can help I have the mac allister charger that's in this thread I now have a silver fish 36v li-ion battery I have the 3 pin xlr connecter, the silver fish battery only uses 2 of the 3 pins and I want to use the mac charger with this battery but in the charger there are 2 live wires 1 thin 1 thick so can I connect the wires to the3pin xlr and do I only use the thick red wire or do I connect both reds to 1 of the xlr terminals or should I not do this at all and why , thanks if you can help
December 17, 20169 yr The middle pin connects to a NTC thermistor in the battery. I haven't tried it, but it would probably work if you put a 10K resistor between that pin and ground on the charger.
