wolfie1 Posted September 10, 2023 Share Posted September 10, 2023 Have been looking at 4s lipo batteries and am seeing they are coming to 2 different voltages 14.8 and 15.2, whats the story with the higher voltages and how are the charged? Whats the pros and cons of the differences? 1 Quote Link to comment Share on other sites More sharing options...
Bajadre Posted September 10, 2023 Share Posted September 10, 2023 could be LIHV lipos wolfie a standard 4s lipo pack should be 16.8v fully charged and 14.8v rested etc if your charger can charge the LIHV worth the extra bit of voltage but a standard lipo charger will still charge to normal levels 👍 so normal lipo per cell is 3.2volts and a LIHV per cell is 3.8volts 1 Quote Link to comment Share on other sites More sharing options...
wolfie1 Posted September 10, 2023 Author Share Posted September 10, 2023 I see, so a specific charger is needed for them, so a standard say 8s model running 2 hv 4s batteries wouldnt damage anything on the model? 1 Quote Link to comment Share on other sites More sharing options...
Bajadre Posted September 10, 2023 Share Posted September 10, 2023 yes wolf its just a mode on most modern chargers like NIMH LIPO LIHV etc my old fusion charger doesnt have it but i can still use LIHV packs for my drone i just charge them to lipo volts its like filling your car tank up to 90% instead of brimming it. 1 Quote Link to comment Share on other sites More sharing options...
ZaraDyer Posted September 23, 2023 Share Posted September 23, 2023 The difference between LIHV and standard LiPo packs is primarily in voltage levels. LIHV has a higher voltage per cell (3.8V) compared to standard LiPo (3.2V). Ensure your charger can handle LIHV if you choose that option for your RC vehicle.

LiPos have a nominal voltage of 3.7v, not 3.2v. LiHV is 3.8v nominal. 3.2v is close to damaging the LiPo. 3 Quote Link to comment Share on other sites More sharing options...
wolfie1 Posted September 24, 2023 Author Share Posted September 24, 2023 My charger does do the lihv batteries, im quite impressed with it, bought from aliexpress and has lots of features, will charge 2 different types of batteries at 10a each and was not a lot of money, in the end i decided on just the normal ones. I am correct in saying a 10000 mah battery will get charged at 10a an 8400 at 8.4a 6700 at 6.7a and so on, obviously on a balance charge setting? 1 Quote Link to comment Share on other sites More sharing options...

If you charge them at 1c, that's correct indeed. Which is of course what you should do to keep deterioration to a minimum. Best case would be to charge at 0.5c (so 5A for a 10Ah pack), but that takes considerably longer and isn't really viable for many. You can charge at 2c (20A for the 10Ah pack), but that's harder on the pack, and some don't support it in the first place.
