| Higher capacity Li-Po Batteries for handheld? (SOLVED) |
| (1/4) > >> |
| Bender:
I have 2 Li-Ion Li-Po batteries for a portable system I want to wire together for a longer run time I undertand that this should be done in parallel, but there are 3 contacts, do I simply wire the corresponding contacts together like this? I know this is a pretty basic question but I've heard of Li-Ion battery exploding or catching on fire if not wired correctly so I'm a little paranoid Thanks! |
| MonMotha:
DO NOT WIRE LITHIUM ION BATTERIES IN PARALLEL. THEY CAN EXPLODE IF YOU DO. Simply wiring them up like that also nicely defeats the thermal protection (which is what the 3rd wire is used for). You have to switch between them instead. Essentially, you drain one, and when it's "close to dead", you quickly switch over to the other one using some electronics. I would not classify this as a DIY project. it is technically possible to put Li-Ions in parallel, but you have to be very careful about how you do it. Again, I would not classify it as a DIY project. |
| Turnarcades:
I wouldn't advise it. It may be wise instead to do use a larger-capacity alternative power source. I was recently viewing some battery hack videos on youtube for a similar reason, and as long as you can regulate the voltage and resistance, a higher-capacity power source could be used. Upgrading the Benderama? |
| Necro:
Don't LiIon's have little microprocessors in them to control charging as well so they never go fully dead or overcharge? (either of which kills the battery immediately) |
| Bender:
Thanks everyone I guess I'll abandon that idea :-\ Actually I just found out that they are Li-Po and not Li-Ion, Does that make any difference? so anyone know a good source to get a 3.7v LiPo I could use? --- Quote from: Turnarcades on April 11, 2011, 08:43:57 pm ---Upgrading the Benderama? --- End quote --- no, this is for another little project I'm working on |
