Great case buddy. How much and can you do custom logo?

Hey buddy. Thank you for the compliment on the case build it's appreciated. For pricing, drop me an email to: ian@coolice.co.uk Yes, the logo can be customised to the buyer so it can be unique. While I have a vinyl cutter, I don't have a vinyl printer, so I prepare the artwork to the customers' liking and then get it printed for application on the deck panel(s). Chat soon. Ian Contessa

very nice, but 1 critique.... I didn't see any heat shrink on all the xt60 connectors. May not ever be a issue but if it is, and you have a LIPO SHORT OUT its gonna be a VERY BAD DAY!!! Totally worth the 10 cents worth of heat shrink, wouldn't you agree?... Unfortunately it makes me wonder if there's any other issues / over sights.

Hey. Thank you for the compliment on the build it is appreciated, this is another one which has turned out great and the customer is pleased having received it today. I appreciate the concern, but I'd like to go over the points you’ve raised and address them. Correct you do not see any heat shrink over the XT60 solder joints which you can see in the video and with good reason to as the wires are soldered at 90 degrees to the connector due to space limitations, so heat shrink would not work in this scenario. But this is a practice I have used multiple times over a great many builds without issues and it works well, so as you rightly mention there is no issue here. With regards to a LiPo short circuit, should this happen it would effectively start at the charger end of the line, now as there are components inside the charger which would vaporise/get destroyed quickly should a short develop, this would effectively stop the situation getting any worse as the reason for the short circuit is no longer present. Some chargers even have fused outputs to help here. Of course during any failure like this predicting the outcome or path of damage is impossible. Outside of this the only other possibility you could argue is if the soldering joints to each connector are not of good quality, creating a point of high resistance which in turn creates heat and can then lead on to wires becoming unsoldered. However, my soldering skills are very good, meaning my solder joints between wire and connector itself are in turn also very good, eliminating this possible scenario.

However, my soldering skills are very good, meaning my solder joints between wire and connector itself are in turn also very good, eliminating this possible scenario. Dirty connector contact points following repeated connection and disconnection in use is another potential cause for high resistance to develop over time and so I do advise regular cleaning of the frequently used connection points. In his instance these would be the main charge point XT60’s and JST-XH balance ports, which can be subject to carbonization caused by any electrical arcing on contact, also any other dust/dirty from the environment interfering with the electrical mating surfaces. This is a problem for any connectors mating surface, especially those being used a lot. But the ones in the photo are usually plugged in once and left in place until such time as the charger is removed or changed. In either of the scenarios above, a short circuit at the charger end or bad connection point, none of these is going to be fixed or avoided by the addition of heat shrink, as this will quickly melt and let the wire pop free anyway. So is something we want to avoid happening in the first place. If this happen then quick disconnection of the LiPo and power source into the charger itself will be needed, hence the guidance of not leaving LiPo’s charging unattended. The other option would be to use fused charge leads/boards, as some of my customers do using commercially available boards. Also have my own custom parallel charge board with Polyfuse’s and a 30 amp fuse on the positive charge wire input. With regards to your last sentence of other issues / over sights in my products, as a former mechanical and electrical engineer with many years of experience behind me and a general ethos of holding myself and my products to a very high standard of workmanship, this comment I feel is both unnecessary and a purely personal opinion based on no real factual information or knowledge. If you would like to discuss this further, please do not hesitate to contact me directly via ian@coolice.co.uk and I can cover any additional points you might want to raise. Regards.
