Lipo Battery Chargers

To me Lipo batteries are great especially for racing. They hold their voltage and power even after 1 year of racing. You can also keep using the same lipo battery several times in a day without noticing a power loss.

And great thing is Lipo battery chargers are very cheap. Personally I use the LRP pulsar 3 and an old Imax B5 charger. The LRP is more expensive as it has other features such as motor break in, discharger, etc. However when it comes to charging Lipo batteries, the B5 and LRP gives same result. Basically charge the Lipo to 8.4 volts.

What is important is to ensure the battery connector is very good (i.e. clean, strong contact). Lipo chargers are sensitive to the voltage reading in order to do a proper charge. I’ve experienced seeing my LRP suddenly spike to 8amp charging rate (even though it is set at 3amp). Later I discovered it was due to a dirty deans battery connector.

So be careful, keep your connectors clean and from time to time take a look at the charge rate to see if everything is running as expected.

Lipo’s will also expand and even burst into flames if overcharged. My tip is 1) use a good lipo charger, 2) use a good battery connector and 3) charge in a Lipo sack.

Hope this helps you out.
