- Here's how I did it. There are probably many other ways. If you dare to follow these instructions and something goes wrong - it's on you. But, please send pictures of the fire truck!
The principles included are probably compatible to most all e-bikes. You should wire these in parallel, not in series.

Brilliant - I've been searching for a blue-sky thinking genius wirh the talents needed to do this rather obvious thing with any ebike(esp.folding) with an in-frame battery.
I've got a similar setup on my engine x. I too used a chopping board and a 10ah china blue. The battery sits on velcro pads attached to a neoprene rubber mat stuck to the board. There's a short clip on my channel showing the setup and later I installed a 100anp isolator switch so I could unplug it without sparking! 23ah in total and about 50-60 miles on pas 2-3. I also installed a power analyser which sits on the handlebar and I wired it in from the balancer kit up to the bar and then back down to the controller. It showed a max draw of 19amps at 960w! Easy job to do and like you I was no expert in soldering but it was fun.
Personally I am happy to increase range by just carrying an extra battery and not go through the complications of wiring it in line. Very interesting to see other options though.
Did you have to turn off regen? I know they state to not use a battery balancer with regen brakes, but I did not know if they worked fine with the much smaller hill regen on these ENGWE's?
Great video! How far can you go now with both batteries? Also, I would like to know your seatle bag and where did you buy it at? Thanks
Thanks for your video! My GForce T42 is a similar folder and I started by upgrading my main battery to 20AH in the bike tube. My second battery will be in the rackbag. Planning on a 52V 20ah and the Sparks Blender that allows for different voltages. Your XT90S connectors looked like a good choice for hooking it all together. Did you use heat-shrink tubing over your splices or just elec tape?
my man you have no idea how many yt videos i had to watch, trying to figure out what connectors my enigine pro has, i came across your video but then saw its for ep 2 pro and didnt watch it, then i was like why not watch this as well and here not expecting anything to gain, I learn the connectors are called dean connectors.
Nice work and a range test would of been nice too..
Can we just disconnect the 2nd battery and run the bike with the frame battery only as normal if needed
Same I am wondering if it would work on an Engine Pro which has regenerative brakes but can be disabled.
With that second battery, is it possible to turn off the main battery and taking off the key without it turning off the bike?
im doing a duel battery mod on my bike too for longer distance ride
I thought the higher the Voltage, the higher the speed?
So I ordered a second battery (48v 13ah) for my ep-2 pro. Battery and balancer using the same plug as ep-2 pro. I hope it's easy plug and play operation :D
Why not get the same battery and just keep the spare in a bag mounted on the rack? That's what I'm going to do. No mods.
Dual Battery Parallel Controller:: THIS DOES NOT WORK FOR BIKES WITH REGENERATIVE BRAKING!
Sorry, man, but that looks like one miserable ride.
what's the name or the link to this A M A Z I N G seat?
