Makita BCC02 vs BCC01: Multi-Battery Charger Cases That Charge Overnight So You Don't Have To

Introduction

Makita’s new BCC02 and BCC01 take a familiar Mac Pack style carry case and build a multi-bay battery charger into it. The idea is simple: instead of cycling batteries through a single or dual charger one or two at a time, you drop everything into the case at the end of the day, plug it in overnight, and wake up to a full set. This comparison covers both versions, because they differ in one important way beyond the bay count.

How These Charger Cases Work

Both units are built around the Makita DC4002 charger module, which slides onto the back of the case and clips in with a simple on/off arrangement. Neither is a rapid charger. Each unit effectively runs three banks of four on the BCC02 and two banks on the BCC01, charging one bank at a time. A full set of four flat 4Ah XGT batteries takes 2 hours and 25 minutes per bank, so a completely full case is genuinely an overnight proposition rather than a lunch-break top-up.

There are a few differences from the rapid chargers you may be used to. There are no little charge-complete jingles, and there is no fan built into the case itself, so hot batteries will not be cooled before charging starts. Indicators behave as you would expect from Makita’s 40V chargers: a slow flashing blue while charging, solid green when done, and a fast flashing red if there is a fault with the cells. The charger module itself has a light that only flashes red if it overheats or something goes wrong, and the vents should be kept clear.

Makita BCC02: The 12-Bay Option

The BCC02 holds twelve XGT batteries in a Mac Pack 4 style case with a transparent lid, so you can see at a glance whether everything is blue and charging or green and ready. It takes 4Ah batteries, along with 2Ah and 2.5Ah in any combination, but it will not physically fit 5Ah or 8Ah packs, and 18V LXT batteries cannot be charged in it. Fully loaded with twelve 4Ah packs, that is 48Ah or 1,728Wh of stored capacity.

Charging is where things get interesting. Makita’s literature suggests charging runs row by row, but in practice the charger will pull any four batteries that need charging, no matter where they sit in the case. If you pull a battery out mid-charge, another one further down kicks in. That makes it a genuine set-and-forget solution: chuck batteries in any order and it finds the ones that need topping up. A full case of flat 4Ah batteries needs roughly seven and a quarter hours, which confirms its role as an end-of-day, plug-in-overnight unit rather than an on-site rapid charger. It is also designed to stack and clip onto standard Mac Pack boxes, with folding side handles for carrying, and the lid can be removed entirely if you want to leave it on a shelf with open access.

Makita BCC01: The 8-Bay Option With More Flexibility

The BCC01 drops to eight bays, laid out as four on each side of the case, but gains two significant abilities. First, it fits the large 8Ah XGT batteries, which the BCC02 cannot accommodate at all. Four flat 8Ah batteries take 4 hours and 40 minutes, so a full case of eight completely flat 8Ah packs needs around nine hours and 20 minutes, which really does demand an overnight routine.

Second, using the adapter released when the 40V XGT platform launched, it can charge 14.4V and 18V LXT batteries. The adapter fits the BCC02 physically, but no battery can be seated on it there, so it is only usable in the BCC01. In theory you could dedicate one side of the case to 18V packs and the other to 40V, or pull the adapter out whenever you need the extra 40V bays. A 5Ah 18V battery takes 135 minutes per bank of four, noticeably slower than a rapid charger but still done by morning. Output current sits at 1.6A for 40V batteries and 2.1A for the smaller LXT packs, versus 6A on a standard 40V rapid charger, which is why the multi-bay units trade speed for capacity.

Overall Buying Advice

The choice comes down to your battery mix. If you run 4Ah XGT packs as your daily drivers and want the largest possible capacity to charge overnight, the BCC02’s twelve bays and its ability to stack onto existing Mac Pack boxes make it the natural pick. If you own 8Ah batteries or still run 18V LXT tools alongside your 40V kit, the BCC01 is the only one of the two that can handle those at all. Neither replaces a rapid charger for quick turnaround during the day, so many users will sensibly keep a rapid or dual rapid charger for urgent top-ups and let one of these cases handle the overnight bulk charge.

Practical Details Worth Knowing

Both units are IPX4 rated, so a little rain is fine, though it is worth noting the rating applies to the unit rather than necessarily the charger module. The lid can stay on while charging thanks to a seal, which makes sense in cold or wet environments, but in hot summer conditions leaving the lid open during charging is the safer bet. There is also a padlock hole in the lid and the body for basic security, though a determined thief could simply carry the whole thing off; a fully loaded BCC02 plus a loaded BCC01 stacked together weighed in at just over 40kg, so these are hefty units once full and you really want the Mac Pack trolley for transport.

One quirk worth knowing: indicator lights do not always show on batteries that are simply waiting for a bank to free up, so a dark slot does not necessarily mean a fault. The chargers appear to work through batteries in the order they were inserted rather than strictly by physical row, which explains some of the light patterns you will see through the transparent lid. For anyone with a dedicated battery storage cabinet, these cases double as storage and charging in one, which is arguably their best trick.

Conclusion

Neither the BCC02 nor the BCC01 is trying to be fast, and pricing was not available at the time of writing, so expect a premium positioning when they arrive. What they offer instead is capacity and convenience: all your batteries in one place, charged by morning, stored in a sealed, stackable case. Pick the BCC02 for maximum 4Ah bay count and Mac Pack stacking, or the BCC01 if 8Ah and 18V LXT compatibility matters to your kit.
