Recumbent trike battery mount.
« on: 26 September, 2023, 01:32:01 pm »
I'm just starting the process of converting my TWBents recumbent trike to electric power.

Currently pondering how to mount the battery as low down as possible.

Now I know that T Trikes have a mounting kit, but I'm reluctant to pay almost £150 for something that I can possibly fabricate myself.

I've done all the Google searches, but all I can find are mounting kits for T Trike and Ice Trikes.

What I could really do with is finding others who have made their own mounting brackets and hopefully look at pictures to give me some inspiration.

Any assistance would be much appreciated.

Why as low as possible, I have a rear rack with a 17ah battery and to be honest I don't even know it is there, plus it's handy if you want to strap anything on at a later date

I've seen batteries mounted to the back of a mesh seat, which would seem eminently fabricobble-able, and decent enough weight-distribution wise.  P-clips and a bit of sheet metal, with appropriate drillings for the battery bracket, or something.

Natalya's ~12.5kg battery[1] on the rear rack (I molished it into an off-the-shelf quick-release rigid rack box from Rixen & Kaul or similar) has a significant adverse effect on handling, but it's acceptable as she rarely rides faster than about 20mph.  Better rear-wheel traction is a useful side-effect.  More significantly, it means you can't use the rack for other luggage.


[1] 820Wh of LiFePO4, which made sense at the time.

Thanks for the replies, particularly yours Kim.

Following your suggestion, I've created a battery platform suspended from the underside of the seat. I'm considering adding a further bracing strut from the main frame as the 48v 20ah battery seems VERY heavy.

Just awaiting delivery of the motor now.
