After watching Balance Charging: Can you parallel charge?, I realised that I needed a clamp meter. But which one?
I had already purchased a UNI-T UT71D DMM, see Choosing which Multimeter to buy, and I was very happy with it, so the UNI-T clamp meter seemed a logical choice. Everyone seems to have the UNI-T 210E. However, there are a myriad of other options.

Following on from GhettoVaper – an extended GhettoVape III, I thought that I would add, if possible, the ability to balance charge the LIPos via a micro USB port. However, as the battery configuration is 2P, and not 2S, it may not be possible.
This time we are looking at PCB chargers, and Battery Management Systems (BMS).
Following on from B6 based chargers, I managed to fry my SkyRC B6 Mini LiPo battery charger whilst charging a 3S LiFe battery. Now I just get an error message whenever I initiate a charge cycle.

A friend gave me his girlfriend’s Junxin powerbank to have a look at. It appeared to charge up to 100%, at least the LEDs along the side indicated as much, and the torch at one end lit up, but once it was disconnected from the mains, there was no charge available to charge a phone.

A friend gave me an Eloop E10 powerbank to look at, as the USB (A) and USB Micro connectors had slipped out of place.

LiFePo4 batteries are safer to use than LiPo, but there are some drawbacks. They are often used in RC for transmitters. This blog was initially part of RC Transmitters – Turnigy 9XR Pro, but has become its own separate article. Continue reading LiFePo4 Batteries
A QBrain quad ESC was on eBay, Q Brain Quattro 4 x 20A Brushless ESC 2-4S 3A BEC for multirotor quadcopter for £20. It is more expensive that four cheap Chinese ESCs, but maybe it is more reliable? Continue reading Q-Brain quad ESC
