Would every one be comfortable with me removing a cell from my LiPo? As the voltage is to high, and I can't afford another one? It should be a simple procedure, and I will try to protect the cells well. And it well be tested thoroughly after? And I will try to rap it in heat shrink? Would every one be ok with this? As I know there more risky than other battery's so people may be uncomfortable standing next to a tampered with lipo, so may not want it done?
The cells are stuck together quite well and you risk spliting the sleaving by pulling them apart, I don't think any eo's would want modded lipos in use.
Check to make it official but I don't think many people would even try.
One wrong move and you haven't got a battery but an incendiary device.
Not to mention you could give yourself some toasted fingers if you accidentally touched 2 contacts. I put 5mm deep holes on my thumb and index finger with a pair of 1.5V NiMHs when I was building my first ant... stung like a (insert appropriate word here) for 2 months.
Sell the current one, and buy the right one.
Ahh right ok thanks, ill try and get another one then
Also there not put together as easy as Nicads etc... The cell tabs are crimped together with a special machine, not soldered... And I think the cables that are soldered onto the tabs are held on with solder that melts at a higher temperature then normal... So hard to remove.
25-30 quid will get you a perfectly suitable new 4s LiPo, and you get to keep the current one for a machine that will take 5s.
Or as Mario said, as long as the battery has had a healthy charge life you should be able to sell it and cover the bulk of the cost of a new one, if not cover it entirely.
ahh right, well ill have to try and find some money soon, as im going away for a bit (sadly mean im missing the champs) and if i order the lipos when i get back they may not arrive in time for an event I plan to go to, and i would bother butchering my Lipo, shame its not like NiCd/NiMhs as that would be an easy fix!
