LiMnNi Rechargeable Cell in a C Battery Form Factor


#1


Jim Trezzo just sent us this link to a rechargable LiMnNi battery. This looks VERY promising for future OpenROV development. $10 isn't too bad, either.

It will probably require a custom PCB to manage the battery packs, but that should be doable.

I think those would be better: 8 pcs tenergy D-size 10,000mAh Link Amazon and it is possible to buy 20pcs

I was wondering about this (upgrading the power). For battery management one could obviously simply use a battery holder such as the link below and clip one of these batteryspace/powerizer overcharge protection circuist (I bet the sell a 3.7V charger) to the leads (or properly clip two of them to a 7.4V charging chip or whatever if connecting multiple in series). BUT I realize that I dont even know what the power req's are for the system? There are something like 6 1.5V C-cells in series in the standard openrov? Thats going in to the cape or something and then powering all the motors and servos and arduino/beaglebone? Just realising that there is a lot I dont know right now about this thing coming to my doorstep :-)

edit: I just found this earlier post bringing up the issues of the different weights with lipo and other good stuff. Just catching up to the forum stuff, cheers
