LiPo

[plargen]

can you use normal chargers from NiHm on LiPo battery's or do you need a special charger

[Anttazz]

Some can do both, but are primarily LiPo. What charger do you have?

[plargen]

just the bog standard rc 1s

[Anttazz]

Wouldn't really say there is such a thing, most LiPo chargers I've seen though advertise it with lots of large writing on them so I would assume yours is not one of them. They would also have a balance connection.

[plargen]

probably easier and cheaper to stick with NiMH battery's and chargers then

[typhoon_driver]

for lithium polymer, no you can't however there is a way for the lithium A123 cells using a dapter. A bit of kit that sits in between the charger and cells and cuts off at the right voltage.

Most modern day chargers that can do enough Nimh / Nicad cells can do Li-Po and have a built in balancer.

I got an iMaxB6 for £8 On ebay. Here's one for 99p..... Whether you trust it is at your own discretion.

ok will look into it a bit more thanks

I know this is mostly resolved, but the build rules state chargers must be built for the same chemistry of battery. So you can't use NiCad on LiPo, for example.

I have been reading the rules with regards to LiPo batteries and there is one thing that I have been told a few times but doesn't appear to be in the rulebook; Metal boxes for lipos.

I have been told that Lipos have to be charged in a metal box and/or a Lipo sack, and should also be in a metal box inside the robot, or have at least a 2mm thick metal base underneath to protect the floor if the lipos go up.

Can someone clarify this ?
