84v 30ah Lithium Graphene Battery (20s 3p)

Postby erinmarshall.invent@gmail.com » Sat Apr 29, 2017 1:06 pm

For sale i have a recently made Hi power pack made from Turnigy Lipo packs. Each pack has a discharge of 15c-30c(peak).
I derated the batteries to 10c-20c to ensure a low amount of stress on the cells. They have less than 30 cycles on them and are all with in 0.1v of the highest/lowest cell. These batteries have twice the cycle life of normal lipos and even then ive never discharged the pack below 75v or charged past 83.2v

This is a serious pack with very little voltage sag at 200amps continous. Capable up to 600-700amps peak. Something no ebike is capable of with any controller less than 36fets.

I am a Navy Nuclear Electronics Tech getting ready for prototype and need to start saving for an actual car so im parting out my drag bike. As keeping it is a constant money pit (fast enough doesnt exsist). Help me quit my addiction lol.

I used a powerlabs smart charger to keep them in balance every 10-12 full cycles. They dont need a BMS as long as you monitor the cells every now and then. This is my 5th lipo pack and ive never had a problem, just follow proper precautions.
No BMS was used since they dont cope well with high amperage.
You can find a BMS around here for them. But i have not modified the balnce terminals in any way.
They are all individually 5.5mm bullets. The total pack at 84v 30ah is terminated with XT150 connectors.
I can ship to UK.
