Those latest NiMH batteris (over 3300 mAh) could be used 4A - 5A to charge it. (For those unmatched or unzapped batteries, don't charge with a current over 5A, otherwise the battery will become ...

Motorman always encourage good batteries.  Do you go to Tamiya USA official track a lot?  Looks very nice in picture, and it opens to public for free on Sat.

HiHi,

There is a lot of reasons for battery to die. But usually, it will not die as sudden as in your case. If it do so, your battery must have been overheat a lot, say, 70-80 degree. I through your battery die was owning to battery quality itself. You may check the inter-connection of those cell. May be one battery cell die and cause the whole pack disconnected.

For charger, much more fits your budget very much. Pay $200 more and it will not disappoint you.

The best method is to discharge the remained power before you charge it up to play. If you expect will not use the NiMH battery for a long time, you have to fully charge the battery before put it into the box.

多謝 各師兄賜教.....
咁用咩放電好呢??

用番排sanyo電放晒佢,搵弟部機叉5A,再放一次,再5A叉,睇救唔救得番.

For cycling or discharge a full charged battery........ I suggest use 10A discharge to 5.4V first and then continue use 1A to discharge down to (5.4V - 5.0V)... and unplug..... after the battery cool down, you could recharge it again. This is a good cycle method.

Why need 10A and 1A discharge: (6 cells batteries pack for example)

10A discharge ----> same situation as running on the car. (unmatched and unzapped batteries are not good for 20A, 30A discharging and I don't suggest high current discharge since it harm the batteries very much and generate a lot of heat)

After "10A discharged" to 5.4V, the battery still remains a lot of power and it doesn't really 100% discharge during this period.

Then use 1A to discharge to 5.4V or lower voltage..... the battery really reach 100% discharged this time. (This process is called equalized.)

Finally, the battery pack could be recharged again after cool off. (Cyling NiMH batteries not more than 3 times per day was suggested)

Buy a charger with 0 to 10 A discharge function, then you could have the job done.
