Just got the tape measure out & my latest cells "might" just squeeze in those boxes,then thought...
External? = so what do they measure internally please?

Old cells are slightly wider than new cells,but much shorter than new cells,old cell = 1000 Mah,new cells = 2200 Mah,Old cell 20C,new cell 40C.
New cells are for an utter mental powered box,capable of upwards of easily 350+ amps.I don't require 1/3rd of that output though,I just want the increased capacity as I'm getting tired of having to recharge boxes to ensure they don't expire mid-evening when out.I've also decided to include a voltmeter in my boxes (especially the 8.4V box) as the 4.2V box tells me via taste that the box needs recharged but the 8.4V I had to take it all apart,split the cells up again & recharge each cell individually as I'd over-discharged the pack so the iMax charger couldn't be used,before reassembling the cell pack & then checking with the balance charger.
I'm also trying to work out if I can insert a zener diode in the 8.4V box(in the switch wiring to the mosfet?)to help protect it from over-discharge.
