I put my bag battery in the triangle

What are the dimensions of the actual battery before you put it in a bag (could get a bag / modify an existing bag to fit )

My bag battery is the smaller 36V 10AH. The OP wanted something bigger, 36V15AH.
Dimensions:
36V10AH 17cm x 7cm x 7.5cm
36V15AH 21cm x 8.5cm x 7.5cm
My bag houses also the 85TS controller. There isn't much excess wires, they are also tucked in the bag. The LCD is built into the stem. I did not bother with the throttle as starting off on the 85TS is instantaneous. The overall result is pretty neat and pleasing.

So after much measuring, sketching, and cardboard engineering, with helpful info and advice from folks here and Andy at Woosh, I have worked out a reasonably practical way to mount the DP 20Ah battery, in spite of the very limited space. It isn't quite ideal, or as simple as just 2 or 3 screws into bottle mount holes, but I'm confident I can do it.

I did consider the bag battery, but felt that a solid mount was preferable, as were the bigger capacity and branded cells.

So this morning I ordered a Tongsheng 85TS kit with the 36V 20Ah downtube mounted battery, a throttle kit, and hydraulic brake sensors, all from Woosh for £569.

I'll take pictures and make notes as I go through the installation, and post here, maybe much to my embarrassment if it doesnt go to plan.
