Charging a Yamaha battery and a Bosch battery with the same charger.

[Johnthedentist]

Greetings from Somerset, UK. I have a Haibike with a Yamaha motor/ battery (500W/hr). My wife’s bike is a KTM with a Bosch system ( also 500W/hr battery). We like to go on multi day tours, and charge up at hotels overnight. Is there any way that we could make a charger or adapter so that we could tour with just one charger-rather than having to carry one each? Anyone solved this problem?! Thanks.

Of course, they have to be the same voltage, and it's also good to have the same amperage. In my years of traveling with chargers and batteries first with cameras/camcorders and now with ebikes, it's a bother to run two or more packs on the same charger.

Let's say you have a 2A charger and 14 AH batteries. If you finish the day with both flat, you'll need at least 6 hours to put 12AH back into one battery, and then another 6 hours on the second. If both of you are asleep and forget, there goes the next day.

actually they both are the same voltage. but how they charge may be different I now bosch has a temp monitor on the charger. there bosch is 4 amps and I bet the Yamaha is that or close. but the plugs re different. so right now your stuck with two chargers.

Both systems are OEM and it is not possible to share a charger. Think of a battery as a computer with many cells inside.

It's not as simple as an automotive charger with just 2 leads. There is communication between the Bike battery and the charger. Bosch does make a travel charger if you insist on having something smaller.

Sorry, the world of smart battery packs is unknown to me.

Give me a dumb pack but if it is going to have some safeguards, put in GPS for theft and 9-1-1 calling in case of fire. Ha ha.

Not just smart battery packs, they are "intelligent"
"The intelligent Bosch Battery Management System controls the battery‘s recharging and discharging functions and protects the cells from overload."

but it is with Bosch.
Apparently it's on sale til Dec. 31.

Careful! Not exactly what most will want to risk.
"XLR to Bosch Adapter. Initial Pilot / Beta Batch for Early Adapters.
Note: Depending on circumstances, you will likely need to "force start" the satiator by pressing and holding lower button to start charge process."
