Nicd battery pack thermistor.

This particular battery pack has a nominal voltage of 9 6v 8 cells in series 1 2v each. I have searched everywhere online and it appears that no one else in the universe is experiencing the same issue as me. It was above the nominal 9 6v of the pack. Hopefully someone here can shed some light no pun intended on the subject.

I plan to lay out the cell holder like in the picture below. Organized by voltage we offer packs from toy grade to competition grade and everything in between. Does anyone have a better way of building them other than soder each battery. Where can one find the temp sensor switches that are on the milwauki red lithium and dewalt 18 volt nicad battery packs.

All 6 of my milwaukee 18v nicd battery packs are dead. I refuse to pay 80 for new ones so i rebuilt two of them with new 1 2v sub c nicd cells same ones used in the original pack. Excessive loading of the battery packs can create a dangerous overheating situation. They provide critical temperature data required to keep the li ion battery in the optimum condition during the charging cycle.

This method does not require an end of charge sensor and ensures a full charge. Ntc thermistor temperature sensors are a key component in li ion battery charging and safety. You should always measure your battery pack before plugging in your tool. The thermistor chip on fr4 sensor has been a solution for harsh environments with the possibility for battery fault conditions.

I verified the voltage on the battery pack and it was fine. Whether you re powering your rc car or building a battlebot we have a pack that suits your needs. I found a battery spot welder but it is like 5 000 bucks. One energy centre norton shores mi 49441 ph.

The holders are the keystone model 92. Careful management of temperature during charging prolongs battery life and avoids hazards inherent to li ion batteries. I m laying out a pcb for a nimh single aa cell charger following the avr450 application note battery charger for sla nicd nimh and li ion batteries but i m not sure where to place the ntc thermistor that will read the cell temperature throughout the charging process. So a 100 mah battery would be charged at 10 ma for 16 hours.
