forgotten /lost some of them.. mixed in other threads.. so I figured
I'll start one last thread on this subject for my own resources..
When charging Lipos.. is the recommendation to charge at 1C over 1
hour.. or if 3200mah then 3.2amps max charge.. and for better life..
only 75% of this value.. say 2.8amps?
I've been looking at chargers, trying to decide what is the best/
cheapest option.. I see alot that are Lipo only, and also include the
balancer.. built in.. but usually their max charge is like 2.0 amps or
similar.. to me this may take quite awhile, even though typically I'll
be charging these in a security firesafe box (no vents) in my house
while supervised (does this security box seem like the usual safe
Do I want a charger that is ideally at least the 1C rate of my highest
mah battery pack? Should I be charging at 75% max value?
Ideally I wanted a charger that also had AC adapter ability, i've seen
several that offer this, some that also do Nicad/nimh.
I will still be doing nicads with my older zagi till I convert it.. so
I thought maybe having 2 chargers that still did nicad would be good?
(IE: cig lighter adapters, 2 at same time, charging two nicads, in
the car, is this bad on the battery for several good charges?).. if
this idea is not useful, then I would probably go with a lipo only
Charging Lipos in the field: Safe to plug a single charger into the
cig. lighter adapter, and put the battery in the security fire safe
box outside the car while charging? Or do some people use a different
setup.. a seperate Lead acid battery (like an automotive battery?)..
outside of the car? I'm not clear on how this is done or what exact
battery is used in this type of situation.
Balancers.. I'm assuming if the charger doesnt have a balancer.. I can
just buy a balancer and attach it to the charger (usually around $30
Final area of confusion.. if the charger doesnt have AC adapter
ability or a cig lighter adapter which could go in one of those AC to
DC converters for in the house.. are most people doing the whole PC
power supply idea.. or purchasing a pre-modified psu?
I could attach multiple chargers to one of the PC power supply setups
could I not? And charge multiple Lipos at the same time.. IE:
3200mah at 3.2amps x 3 would be roughly 10 amps, so if the PSU is
rated 10 amps or higher I should be fine?
It would also be nice if they made a charger/cycler that did
Nimh,nicad, and Lipo :)
I already have a 300 watt power inverter for in the car, if the
charger had AC plugs too.
I've come to the conclusion from what i've read, that i can buy any
charger.. i would simply cut the leads and put on the matching
connector for whatever battery (or vice versa) that I would need.
Sorry for the mass questions again, I'm just trying to pool my
thoughts into one single thread on the same subject..
Here are the chargers/balancers I've found so far:
Thunderpower, has ac pack.. $79
have to add balancer.; 2-5 cell; 5amp max
0.2a/cell to 2amp/cell, 2-4 cells $67 (add $13 for ac plugs)
Team Orion to 6amp with balancer, balancer connector is JST $48
Astro 109: $109 (notes say not to use with car battery?) 1-9cell, 7.5 amps max
(must add balancer)
Great Planes Triton JR
$79, nicad or nimh, or 1-4cell lipo.. 0.1 to 5amp .. limitted to 1C
for lipo.. add balancer
ProPeak 1-4 Lipo Auto charger (100-6000mah or .1 to 3 amps)
CellPro 4s $69 3amp/1c max (add balancer again)
*Balancer idea: $29.99
The propeak seems to be cheapest.. but it maxes at 3 amps, so on
3200mah pack, its slightly under its normal speed of charge? But
