19.2 V battery question !!

[Tynan]

Hi there

New member here with a very basic question (I am no electrician!). :saddam:

I have a 19.2 V / 9000mAh battery (for an electrically assisted bicycle) and the wiring on the charge end needs a little attention. Basically one end of the battery gets plumbed into the bike and supplies it with power and the other end is the end that gets plugged into the charger when recharging.

At the charge end one of the wires is broken and needs soldering together, I am ok with the soldering / heat-shrinking and general repair duties but have zero knowledge of how electricity works with these batteries - so to my question . . . . .


When the battery is unplugged from the mains and the charger (and disconnected from the bike) is it safe for me to touch the red wire in this diagram ? (diagram below) ? To clarify I am talking about the red wire coming from the battery at the charging end, when the battery is disconnected from everything (from the charger / mains and the bicycle) is it ok to handle the red wire that protrudes from the battery ?


Thanks in advance for any help on this !!

How do the wires terminate on the back of the socket, are they soldered or do they have push on connectors.

The wires coming out of the battery look like they might be long enough to trim the damaged sections and connect back on without an in-line repair.

Quite a nifty looking bike. How long does it run for on a single charge and how much peddling do you have to do?

Unfortunately they are soldered into the back of the socket ! Still, the in-line repair shouldn't be too taxing, even with my limited skills.

Yep, it's great fun for zooming around town, 15.5 mph top speed (20mph in non-E.U mode) . . .

Single Charge =

Around 20 miles range with pedal input.
Around 8 miles range with zero pedal input.

You can buy a newer Lithium-ion battery that ups the range and speed by around 20% (but it's a little pricey).

Full charge takes around 3.5 hours, simply plug it into the mains, you can throw the charger into your backpack/bag as it's very lightweight - and recharge wherever you find yourself.

Aint gonna put any usefull input here but think the OP should get a gold star for the diagrams alone... if everyone did this we would have a easier task with regards to helping them.
