Bunch of these available on AliExpress. For a Heavy Duty version, check Area 13 Ebikes (perviously know as Bolton bikes). I have the one from Area 13 using a Lectric 10ah and a 15ah Unit Pack Power batteries. Works seamlessly. It first uses power from the battery with the most charge/higher stored voltage, until both batteries are at identical voltage. Once both have the same voltage then it sips power out of both at the same time.

I’ve got that system, works as described and took me 20 minutes to install. It’s now on my wife’s bike as well. Double your mileage at half the cost of a long range battery. Nice!
