One of the smaller packs i make, this one for a headlight. Please be aware of the many flaws in this tutorial which can not just ruin your projcet but also catch fire or kills you.
i repair batteries for a living and like these DIY tutorials. But there are some issues that i dont agree with in this tutorial:*If the replacement battery cost more then it usually has far better capacity the your old one. *If you change the chemistry you must also change the charger which is another €10-20.*There is good chance the voltage is to low or too high if you change to lithium so it can destroy the power tool.* If you need to repair a NiCD/NIMH/Ni-ZN battery be sure to buy NIMH cells (usually 4/5 SUB C sizes with soldering tabs). Lipo is not recommended for DIY packs since they can overheat and burn if mistreated! Lipo packs also need to have BMS which some hobbypacks like these dont always have!Safety first!
Way too advanced for me but i know some people in stockholm that made one at maker space. Was very impressed!

Awesome, will actually try to make this. However will it work on higher voltages then "7-15V"? like 24-48V?

Is there ANY commersial products i can buy instead of messing around with high voltage and current? Trying to run a spot welder but i trip all breakers under 20A.
Ive been checking my broken chargers and most have NTC connect in series with the negative and then a 471kd07 Varistor beetwen pos and neg. Isnt that enougt? The NTC con will work if when temp is high (all currents) and Varistor will work when current is high and NTC is Hot and lower the resitansa is current is high? Only 2 component ans seems to be standard in most chargers.
