Afternoon all,

very quick (noob) question, i've got a couple of LiPo's which upon looking at the instruction booklet it recommends a charge current of 12A (for reference my LiPos are LRP P5 HV) and the charger I had my eye (SkyRC S65)on is rated at 6A. Does it make any difference if I was to charge at 6A

TIA

ps I would have linked the items in question but i've not made enough posts yet.

12 amp vs 6 amp 2x as long...look at a charger that will charge at a higher rate than the 12 like a toolkit M8 if you have a 12volt power supply

Ah, it's to do the with speed. Cool, thank you

Correct. The default charge rate is "1C". For a 5200 mAh pack, that would be 5.2A. (mAh/1000) A 1C charge rate should take about an hour.

Some companies rate their packs for higher charge rates. If you can charge the same pack at 3C / 15.6A, charge time is 20min.

its not default its recommended by others.. see what maximum charge rate is so new era batteries go up to 10c.

Don't think LRP is recommending 12A charging, they're saying it's safe to charge up to 12A.

Are you racing or something else? If racing there's 2 schools of thought. First is buy an iCharger duo that can do 30A or more charge with a discharger and completely cycle your batteries right before a race to heat them up and get the lowest IR. Not going to get into the debates here on the pros/cons of this practice. There are recent threads on this forum already.

Second approach if racing is that it's unlikely you'll be using more than a fraction of the battery capacity during a race. During 5 min races, even on 2wd SCT trucks, I'm not using more than 2000mah of capacity from a 5000-6000mah battery. Onroad is even less. Meaning is only takes about 15-30 min to recharge my batteries at a 1C charge. Which is plenty of time between races.

If you're doing something other than racing and you're running your packs until low voltage cutoff, then it's how much down time do you need or want. Most of my offroad brushless vehicles can't run much more than 10 minutes without the motor overheating. So while the battery still has capacity, I have to stop anyways and let the motor cool off.

Have you tried parallel charging for speed?

I'm not sure, but not all batteries support fast charging. Check if you have one

!c is what is recommend. Faster charging kills batteries faster.

1c might have been recommended back a few year but now higher c is acceptable for those that want the lowest ir possible that's why makers put a max C charge on packs and info pamphlets

Storing them incorrectly does more damage than faster charging.
