Help! Jorvick 24 trike / throttle

[Mee]

Standard Tigershark battery that you can buy anywhere. I gave a link in the other thread.

BTW I've never seen or heard of one of those batteries leaking. In the old days, some cells would leak, but not enough to come out of the battery. I suspect that water has got in and is finding its way back out. In that case, the battery might be fixable if you have the competence to work a screwdriver and voltmeter.

Just to clarify, if I buy a new battery does the mount have the controller in it, and so I just need to make sure that the controller works with my motor and wiring?

When you leave a battery standing for a long time it can go out of balance because in many cases the BMS needs power to check whether the battery is still OK to give power. Sometimes, it takes the power from only one of the ten cell groups, so that one goes down to a level that prevents the battery from giving much power or capacity. The only way to know is to measure. You can get a clue from the outside by operating the charger until the light goes green, then measure the battery voltage on its main terminals. A healthy battery would be around 42v. Anything below say 41.5v should be given some attention to re-balance it. One that's been left for a long time might be as low as 39v.

How does one go about rebalancing it? is it worth me doing this rather than buying a new one? I don't have a charger so will have to buy one and don't want to spend the money on this if the battery is no good/
